Investigation of Degradation in 20-Year-Field-Exposed PV Modules From India by Cross-Characterization Using Electroluminescence Imaging and Thermography
Authors: Pareek Arti , Meena Roopmati , Gupta Rajesh
Published: February 2024

The reliability of photovoltaic (PV) modules is essential for ensuring a smooth operation over the anticipated timespan while operating outside. Examining the degradation in field-exposed photovoltaic (FEPV) modules will help to identify the possible degradation modes that can affect PV module performance and functioning. In this paper, to identify the major modes of degradation in Indian subtropical climate conditions, 20-year-old FEPV modules have been investigated by cross-characterization using dark lock-in thermography (DLIT) and electroluminescence (EL) imaging. Cross-characterization using EL and DLIT images has been helpful in investigation of various modes of degradations in FEPV modules in the presence of multiple degradations. Encapsulant and busbar ribbon interface degradations have been identified as the two main modes of degradation observed in Indian sub-tropical climate conditions. Minor degradations include finger interruptions and cell cracks. A major effect of degradation has been observed on the fill factor and short circuit current, which have decreased by up to 30% and 40%, respectively. The results presented in this paper can be used to understand degradation occurring in a sub-tropical climate and for the non-destructive analysis of degradations in the FEPV modules.
Analysis of the Performance of mc-Si and CdTe Modules Under Soiling Conditions
Authors: Ferrada Pablo , Llaguno Martha Isabel , Marzo Aitor , Lopez Gabriel
Published: February 2024

In this work, we study the soiling impact on the performance of two PV technologies installed in the south of Spain. For this purpose, we include electrical measurements as well as spectral aspects such as dust transmittance, quantum efficiency and the local solar spectrum to analyse their response. The studied technologies were multicrystalline silicon (mc-Si) and cadmium telluride (CdTe) PV modules. The solar spectra representative for clear sky, clean glass cover and soiled glass as well as the spectral response of the PV modules were used for the calculation of the photogenerated current density and spectral mismatch factor. Two cloudless days were chosen for analysis. In terms of the solar resource, these days did not exhibit large differences. Nevertheless, soiling was present to a different extent. When comparing the corresponding power output of the technologies on day 1 and day 2, the power losses at 12 UTC were 3 times larger for mc-Si and nearly the same for CdTe. This result shows that the soiling impacts differently on PV modules having different spectral responses.
Key Aspects of p-Type TOPCon on Textured Surface for Silicon Bottom Cells in Tandem Devices
Authors: Polzin Jana-Isabelle , Krieg Katrin , Richter Armin , Kluska Sven , Benick Jan , Hermle Martin
Published: February 2024

Both-sides TOPCon solar cells are an interesting candidate for a highly efficient and thermally robust Silicon (Si) bottom cell for tandem devices, such as Perovskite-Si solar cells. However, preparation of p-type TOPCon on a textured surface is necessary which is particularly challenging. This work aims to gain a deeper understanding of the limiting factors and thereby optimize the SiOx/poly-Si(p) contact to close the gap to its n-type counterpart. Using symmetrical lifetime samples, we first show that a high level of surface passivation can be achieved using thermally grown interfacial oxides of different thicknesses. The samples strongly benefit from an effective thermal activation of hydrogenation by means of fast-firing. Thus, a recombination current density J0s as low as 23.4 fA/cm² was achieved for p-type TOPCon on textured surface featuring an in situ Boron-doped poly-Si layer prepared by plasma enhanced chemical vapor deposition (PECVD). Moreover, we show that the passivation quality strongly depends on surface morphology. Smoothening the random pyramids’ valleys and – what is more – the tips has a positive impact on the surface passivation.
A Simple Approach for Module Temperature and Power Prediction
Authors: Schneider Andreas , Chochollek Julia , Nierhoff Thomas
Published: February 2024

In this work a mathematical approach to calculate solar panel temperature based on measured irradiance, temperature and wind speed is applied. With the calculated module temperature, the electrical solar module characteristics is determined. A program developed in MatLab App Designer allows to import measurement data from a weather station and calculates the module temperature based on the mathematical NOCT and stationary approach with a time step between the measurements of 5 minutes. Three commercially available solar panels with different cell and interconnection technologies are used for the verification of the established models. The results show a strong correlation between the measured and by the stationary model predicted module temperature with a coefficient of determination R2 close to 1 and a root mean square deviation (RMSE) of ≤ 2.5 K for a time period of three months. Based on the predicted temperature, measured irradiance in module plane and specific module information the program models the electrical data as time series in 5-minute steps. Predicted to measured power for a time period of three months shows a linear correlation with an R2 of 0.99 and a mean absolute error (MAE) of 3.5, 2.7 and 4.8 for module ID 1, 2 and 3. The calculated energy (exemplarily for module ID 2) based on the measured, calculated by the NOCT and stationary model for this time period is 118.4 kWh, resp. 116.7 kWh and 117.8 kWh. This is equivalent to an uncertainty of 1.4% for the NOCT and 0.5% for the stationary model.
Frutosaminas: uma revisão dos últimos dez anos

A manutenção da taxa de glicose sangüínea tão próxima quanto possível dos níveis normais tem sido amplamente aceita como um bom índice de acompanhamento, podendo reduzir significativamente as seqüelas do diabetes. Medidas diárias múltiplas da glicemia não são freqüentemente um caminho prático no controle do diabético, embora pudessem ser consideradas como o melhor método de controle. Durante a década de 70, diversas técnicas para a mensuração das hemoglobinas glicadas tomaram-se acessíveis à grande maioria dos laboratórios, fornecendo uma indicação retrospectiva dos níveis de glicose sanguínea das últimas quatro semanas e têm sido largamente adotadas como uma maneira usual deste mesmo controle diabético. A maioria das técnicas tentam medir a HbAlc, originalmente descrita como a mais abundante das frações glicadas da hemogobina que se encontram aumentadas nos diabéticos. Durante a última década vários métodos foram desenvolvidos para mensurar outras proteínas glicadas além da HbAlc, A descoberta de que outras proteínas séricas são glicadas em caminhos análogos ao da hemoglobina despertou muito interesse quanto à sua aplicação clínica. A albumina glicada tem sido indicada como um índice para o controle glicêmico num tempo de duas, três semanas, um período menor do que o da hemoglobina glicada, mas suficiente para ser adotada como controle.

Published: February 2024

Em nosso meio, o planejamento de dietas e o cálculo dos diferentes nutrientes é, em geral, feito com o uso de tabelas internacionais de composição de alimentos. Além deste fato, as tabelas disponíveis no Brasil são comumente compiladas e/ou traduzidas de tabelas oriundas do exterior. Desta maneira, os resultados obtidos ou a composição da dieta nem sempre correspondem à realidade local. Considerando a necessidade de se conhecer a composição em macronutrientes dos alimentos normalmente consumida pela população brasileira, o presente trabalho teve por objetivo determinar: o teor cal6rico (calorimetria direta), de nitrogênio, o extrato etéreo, cinzas, umidade e de hidratos de carbono (por diferença) dos seguintes alimentos: açúcar refinado, alface, arroz polido, banana, batata-inglesa, café em pó, café infusão, carne bovina, cenoura, chuchu, farinha de mandioca, farinha de trigo, feijão, feijão preto, fubá, laranja, mandioca, mandioquinha, salsa, leite em pó, leite pasteurizado, ó1eo de soja, ovo de galinha, pão e tomate. Os resultados foram discutidos e comparados com os de tabelas internacionais. Recomenda-se o uso dos valores obtidos no presente trabalho quando for necessário determinar a composição de alimentos de uso no Brasil.

Published: February 2024

Para detecção de sujidades leves em sopas desidratadas foi proposta a metodologia descrita pela AOAC 980.27 para cevada, aveia e mistura de cereais desidratados. As amostras foram contaminadas artificialmente com fragmentos de insetos: cabeças, tórax-abdomen e élitros, ácaros e pêlos de ratos brancos. Na etapa de desengorduramento e f1utuação o método foi modificado quando comparou-se os efeitos de dois solventes, isopropanol 40% indicado na metodologia AOAC 980.27, etanol 60% e misturas deles nas proporções 1:I e 3: 1, respectivamente. A média de recuperação de sujidades leves, utilizando isopropanol 40% e etanol 60% (3: 1) foi de: 92,6% para fragmentos de insetos, 43% para ácaros e 53% para pêlos de roedores, não diferindo significativamente (p>0,05), quando utilizouse somente o isopropanol 40%; encontrando-se 93,3% para fragmentos de insetos, 39% para ácaros e 61 % para pêlos de roedores. O método 980.27 modificado, utilizando isopropanol 40% e etanol 60% (3: 1) foi mais eficiente para a recuperação de fragmentos de insetos. A avaliação das sujidades leves, em sopas desidratadas, no método proposto modificado empregando-se a solução de isopropanol40% e etanol 60% (3: 1), foi realizada em 62 amostras comerciais de duas marcas diferentes (A e B), produzidas no Estado de São Paulo e adquiridas em supermercados do município de Araraquara-SP. O total de amostras foi dividido em dois lotes com 31 unidades cada, constituídos por amostras do mesmo tipo, mesma marca e datas de fabricação diferentes. As amostras foram analisadas em duplicata. A maior incidência de sujidades leves (nº 50g), foi para fragmentos de insetos com porcentagens de 81,8% ( 1 a 36 fragmentos de insetos) para a marca A e 82,5% ( 1 a 49 fragmentos de insetos) para a marca B. As duas marcas mostraram pequena incidência de ácaros e pêlos de roedores. Estes resultados sugerem que é necessário a revisão da legislação brasileira, quanto aos limites microscópicos, em sopas desidratadas.

ABSTRAKPenipuan dan penggelapan merupakan salah satu contoh tindak pidana yang merugikan bagi orang lain. Tidak terpenuhinya kebutuhan pokok atau kebutuhan dasar sehingga standart hidup layak tidak tercapai menjadi salah satu faktor adanya tindak pidana tersebut. Kebutuhan dasar yang dimaksud seperti makanan, pakaian, rumah atau tempat berlidung, pendidikan dan kesehatan. Akibat dari kurangnya dalam memenuhi kebutuhan pokok tersebutlah yang kemudian kejahatan terjadi dimana-mana. Salah satu cara untuk menyelesaikan instrumen persoalan yaitu dengan menyerahkan kepada pihak Kepolisan.Penelitian ini termasuk jenis penelitian hukum empiris (yuridis – sosiologis). Sumber data primer pemelitian ini adalah penyidik di satreskrim Polres Pamekasan. Teknik pengumpulan datanya menggunakan metode wawancara dan dokumentasi. Kemudian data dianalisis melalui analisis deskriptif. Berdasarkan hasil penelitian diperoleh kesimpulan bahwa penyelesaian tindak pidana penipuan dan penggelapan di Satreskrim Polres Pamekasan diselesaikan dengan asas restorative justice dengan menerapkan mekanisme Peraturan Kapolri Nomor 8 tahun 2021 tentang Penanganan Tindak Pidana Berdasarkan Keadilan Restoratif dimana dalam pelaksanaannya melibatkan korban/ pelapor, pelaku/terlapor serta pihak – pihak yang terlibat dalam perkara tersebut. Hambatan yang dialami oleh penyidik satreskrim Polres Pamekasan dalam menerapkan asas restorative justice dalam perkara tersebut yaitu tersangka ingin melarikan diri dan seakan – akan tidak mau mengganti atau ingin menguasai sepenuhnya uang yang sebenarnya menjadi milik atau hak korban. Akan tetapi setelah berbagai upaya penyilidikan dan penyidikan dilakukan akhirnya tersangka berhasil diamankan oleh penyidik Satrsekrim Polres Pamekasan dan akhirnya tersangka mengganti seluruh kerugian uang yang dialami oleh korban. Oleh karena itu dihimbau kepada masyarakat untuk tidak mudah tergiur dengan adanya tawaran arisan online dengan keuntungan yang singkat dan besar akan tetapi tidak jelas sistem pengelolaannya yang nantinya akan merugikan korban.

Authors: Kang Hexiao , Ma Yirui , Xie Qiyan
Published: February 2024

In the context of a patriarchal society, men occupy a relatively dominant position in both social life and the workplace. In contrast, women are usually just wives, daughters-in-law, and mothers in the family rather than "women" per se. Based on the awareness of this, the purpose of this paper is to study the process of awakening women's consciousness in the workplace in China and Korea in recent years and the reasons affecting them. The analysis of this article examines the images of women in the film and television works "KIM JI-YOUNG, BORN 1982" and "Fighting Youth" to analyze the changing status of women in the workplace and the main factors affecting the awakening of women's consciousness. The present study acknowledges that the emergence of female consciousness is propelled by intrinsic factors within women themselves. The awakening of female consciousness is driven by women's questioning and thinking, which leads to change.

In terms of popularity, policy, and investor attitudes, the US and China’s current situation is compared. The emergence of cryptocurrency has changed the role of traditional Central Bank monetary policy, making it faces new challenges in controlling economic fluctuations and stabilizing financial markets. In addition, the volatility and uncertainty of cryptocurrencies also affect investors' attitudes and behaviors. In the United States, investment risks in cryptocurrencies are widely discussed, while in China, investors are cautious about cryptocurrencies due to the government’s relatively conservative attitude towards cryptocurrencies. In summary, cryptocurrencies have different impacts on the economies of China and the United States. Due to government restrictions and regulations, China's development of cryptocurrencies in the country has been hindered to some extent, while the United States has become one of the leaders in the global cryptocurrency market. However, the potential impact and risks of cryptocurrencies cannot be ignored, and active guidance and supervision from governments and regulatory agencies are needed to ensure their positive role in the economy. On this basis, investors need to invest rationally based on their own risk tolerance and market trends to achieve long-term economic benefits.

The digital economy is rapidly advancing, penetrating enterprises and influencing their behavior. To investigate how digital finance affects the financial investment decisions of enterprises, based on the panel data of Chinese A-share listed companies between 2011 and 2020, this paper uses a robust two-way fixed-effects econometric model to explore the impact of digital finance on corporate financialization and the heterogeneity of the impact within corporates of different natures and sizes. The findings reveal that digital finance significantly inhibits corporate financialization, with a more pronounced effect observed in nationalized and large-scale enterprises. Therefore, it is imperative for the government to enhance supervision and management of enterprises, as well as encourage and guide them to strengthen their digital finance capabilities to fully harness its potential.

Double tax avoidance agreements (DTAs) play a pivotal role in facilitating international trade, exemplified by China's proactive engagement in 1983 when it signed its first bilateral tax agreement with Japan. Germany and numerous other countries have followed suit, recognizing the importance of these agreements in mitigating tax-related impediments to cross-border commerce. China's commitment to DTAs is clearly manifested in its extensive network of agreements, as corroborated by the OECD's comprehensive list. Remarkably, China has established DTAs with 102 countries and regions, underscoring their global significance not only for China but for nations worldwide. This article comprehensively explores the subject matter. It commences by elucidating the fundamental concepts and principles underpinning DTAs, followed by an examination of their legal regulations and distinctive attributes. Furthermore, it delves into the potential risks inherent in these agreements and their consequential impacts on international trade and fiscal policies. A more concrete understanding is provided through an in-depth analysis of specific DTAs, with a primary focus on the China-US and China-India agreements. By dissecting these pivotal agreements, the article aims to illuminate the legal frameworks that govern international taxation, thus enhancing comprehension of their implications for global economic cooperation and trade.
How Social Resistance is Generated when Social Mobility is Obstructed: A Process-Tracing Study of the 2012-2023 Strike Movement in the UK
Authors: Lu Haoran , He Muxin , Wang Jinghan
Published: February 2024

The UK strike was one of Europe's most extensive and topical social protests in the last decade. Only a little attention has been paid to it in sociology, as perspectives on contemporary society are not popular in academia. To fill this gap, we will use historical, sociological methods to theoretically reconstruct the social structure of the British strike movement and restore its historical-social processes. The relationship between strikes and social mobility in Britain is the subject of this thesis, and it is found that the relationship between social mobility and social resistance is not linear. Instead, it is structured as a 'double helix.' Social resistance does not necessarily begin with a decrease in social mobility, but it does impact the current state of social mobility. Indicators of mobility will be one of the resistance issues, and the official method of counting them is subject to further academic debate and research.
