## 6 Conclusions  
In light of the decline in power generation performance due to overheating of traditional photovoltaic glass curtain walls, this study established an experimental testing platform for planted photovoltaic glass curtain walls, aiming to thoroughly investigate the influence of plant cultivation on their power generation performance. The conclusions are as follows:  
In the photovoltaic glass curtain walls tested in this paper, the average surface temperature of the A\({}_{1}\) photovoltaic glass curtain wall was 45.7 \({}^{\circ}\)C, with an average power generation capacity of 114 W. In contrast, the average surface temperature of the A\({}_{2}\) photovoltaic glass curtain wall was 32.1 \({}^{\circ}\)C, and its average power generation capacity was 190 W. The power generation capacity of the photovoltaic glass curtain wall significantly decreases in high-temperature environments. By reducing the average surface temperature of the photovoltaic glass curtain wall by 13.6 \({}^{\circ}\)C, its average power generation capacity can be increased by 76 W.  
Affected by the planting of _Epipremum aureus_, compared with the A\({}_{1}\) photovoltaic glass curtain wall, the average temperature of the micro-environment on the inner side of the A\({}_{2}\) photovoltaic glass curtain wall decreased by 3.2 \({}^{\circ}\)C within 3 h compared to the A1 photovoltaic glass curtain wall. This temperature was maintained within a fluctuation range of 1 \({}^{\circ}\)C to 2 \({}^{\circ}\)C, while the average humidity of the micro-environment increased by 16.9%. The physiological activities, such as photosynthesis and transpiration, regulate the micro-environment temperature, suppressing the continuous rise in the surface temperature of the photovoltaic glass curtain wall. At any given moment, the surface temperature of the A2 wall was at least 2.4 \({}^{\circ}\)C lower and at most 16.2 \({}^{\circ}\)C lower than that of the A\({}_{1}\) wall, with an average surface temperature reduction of 10.1 \({}^{\circ}\)C during the test period. The temperature regulation effect of the plants is particularly significant during high-temperature stages.  
Affected by the planting of _Epipremum aureus_, the average power generation capacity of the A\({}_{2}\) photovoltaic glass curtain wall increased by 131 W within 3 h compared to the A\({}_{1}\) photovoltaic glass curtain wall, with a smaller fluctuation range of the power generation capacity, indicating relatively good stability. Compared to the A\({}_{1}\) photovoltaic glass curtain wall, the cumulative power generation output of the A\({}_{2}\) photovoltaic glass curtain wall increased by 21.5 kWh over 15 days, resulting in an average daily power generation output increase of 1.4 kWh. On sunny days, the average daily power generation output of the A\({}_{2}\) wall can increase by 1.6 kWh compared to the A\({}_{1}\) wall. On cloudy days, the increase was 0.9 kWh. On rainy days, it was 0.5 kWh. On sunny days with relatively high temperatures, the physiological activities, such as photosynthesis and transpiration, are more intense, leading to a more significant increase in the power generation output of the photovoltaic glass curtain wall.  
In summary, during the growth process of plants, particularly in high-temperature conditions, their physiological activities, including photosynthesis and transpiration, can absorb and convert heat from themselves and the surrounding environment. This effectively mitigates the temperature of the micro-environment and inhibits the continuous rise of the surface temperature of the photovoltaic glass curtain wall, thereby enhancing its power generation performance. Therefore, integrating shade-tolerant plants with photovoltaic glass curtain walls can effectively address the deficiencies of traditional photovoltaic curtain walls in practical applications.
