## 1 Introduction  
Given the current challenges of building energy consumption and the state's promotion of renewable energy construction, building-integrated photovoltaics (BIPV), a building energy-saving program that integrates building and photovoltaic systems. Photovoltaic power generation offers advantages such as safety, reliability [1], and stable energy supply, and is non-polluting [2]. When combined with buildings, it can yield significant economic and environmental benefits [3], contributing to energy conservation and emission reduction goals [4]. The photovoltaic glass curtain wall in the BIPV scheme optimizes the overall energy structure of the building [5] while meeting indoor lighting needs [6], effectively reducing comprehensive energy consumption. However, practical applications of photovoltaic glass curtain walls reveal that ordinary PV glass curtain walls struggle with heat dissipation, particularly in summer [7]. High temperatures in photovoltaic modules reduce photovoltaic conversion efficiency [8] and lifespan [9], leading to increased indoor temperatures and air-conditioning loads, making actual energy savings challenging. Recent advancements in glass technology, such as double glazing, have emerged to address the heat dissipation issues of photovoltaic glass curtain walls. Some researchers have proposed double-layer photovoltaic glass curtain walls that achieve heat insulation and ventilation through natural ventilation [10] and increased inter-air layer width [11]. This research alleviates the high summer temperature problem of photovoltaic glass curtain walls, effectively improving their power generation performance.  
Research has also shown that combining plant cultivation with photovoltaic power generation [12] can enhance the photovoltaic conversion efficiency of modules through plant transpiration while reducing the impact of energy dissipation on ambient temperature [13]. Some scholars have explored agriculture and light complementation [14], investigating the effects of translucent photovoltaic modules on plant growth [15] and coordinating the design of photovoltaic agricultural systems to improve average efficiency. This research emphasizes the mutual influence and symbiotic relationship between photovoltaic power generation and plant growth, facilitating efficient agricultural production alongside photovoltaic power generation.  
In summary, the existing research primarily focuses on reducing the temperature of the photovoltaic glass curtain walls to improve power generation performance, often through structural optimization methods. Common approaches include enhancing ventilation to achieve heat preservation, insulation, and dissipation. Research on integrating photovoltaic power generation and plant cultivation typically centers on photovoltaic agriculture [16], where crop production is the main focus and photovoltaic power generation is a supplement [17]. Moreover, studies on combining light-transmitting thin-film photovoltaic modules with plant cultivation are rarely mentioned [18]. Research on integrating plant cultivation with building-integrated photovoltaics to achieve simultaneous photovoltaic power generation and plant cultivation remains scarce.  
Based on the conclusions and gaps identified in existing studies, this study integrated plant cultivation with building photovoltaics to construct a test platform for planted photovoltaic glass curtain walls. The purpose was to investigate the influence of plant cultivation on the temperature and power generation performance of photovoltaic glass curtain walls, with the research results intended to provide a reference for the field of photovoltaic building and planting integration.
