### Influence of Plants on the Power Generation Output of PV Glass Curtain Walls  
To further verify the influence of plant cultivation on the power generation performance of photovoltaic glass curtain walls, this experiment recorded the power generation output of the two groups of A\({}_{1}\) and A\({}_{2}\) photovoltaic glass curtain walls over 15 days from 1 November to 15 November 2024 (Figure 14). A\({}_{1}\) represents a traditional photovoltaic glass curtain wall, while A\({}_{2}\) represents a photovoltaic glass curtain wall with the introduction of _Epipremum aureus_ planting, with controlled indoor and outdoor environments.  
Based on the power generation output data of the two groups of A\({}_{1}\) and A\({}_{2}\) photovoltaic glass curtain walls over 15 days, the cumulative photovoltaic power generation output of the A\({}_{1}\) photovoltaic glass curtain wall was 21.2 kWh, with an average daily power generation output of 1.4 kWh. For the A\({}_{2}\) photovoltaic glass curtain wall, the cumulative photovoltaic power generation output over 15 days was 42.7 kWh, with an average daily power generation output of 2.8 kWh. Compared to the A\({}_{1}\) photovoltaic glass curtain wall, the cumulative photovoltaic power generation output of the A\({}_{2}\) wall increased by 21.5 kWh, and the average daily power generation output increased by 1.4 kWh.  
On 1 November and 2 November, from 6 November to 9 November, and from 12 November to 15 November, the weather was sunny, with temperatures ranging from

19 \({}^{\circ}\)C to 29 \({}^{\circ}\)C. The daily power generation output differences between the two groups of photovoltaic glass curtain walls were 1.9 kWh, 1.6 kWh, 1.5 kWh, 1.2 kWh, 2.0 kWh, 2.1 kWh, 2.0 kWh, 2.1 kWh, 2.0 kWh, 1.6 kWh, 2.1 kWh, and 1.8 kWh, respectively. On 3 November, 10 November, and 11 November, it was cloudy, with temperatures ranging from 22 \({}^{\circ}\)C to 28 \({}^{\circ}\)C. The daily power generation output differences between the two groups of photovoltaic glass curtain walls were 1.1 kWh, 0.8 kWh, and 0.9 kWh, respectively. On 4 November and 5 November, it was rainy, with temperatures ranging from 22 \({}^{\circ}\)C to 26 \({}^{\circ}\)C. The daily power generation output differences between the two groups of photovoltaic glass curtain walls were 0.3 kWh and 0.6 kWh, respectively. Combining the weather conditions during the testing period, it is evident that on sunny days with relatively high temperatures, the average daily power generation output of the A\({}_{2}\) photovoltaic glass curtain wall can increase by 1.6 kWh. On cloudy days, the average daily power generation output can increase by 0.9 kWh; on rainy days, the average daily power generation output can increase by 0.5 kWh. On sunny days with relatively high temperatures, the impact of plant cultivation on increasing the power generation output of photovoltaic glass curtain walls is particularly significant.  
In conclusion, by introducing the planting of _Epipremum aureus_ on the inner side of the photovoltaic glass curtain wall, the physiological activities of the plants, such as photosynthesis and transpiration, effectively alleviate the temperature of the micro-environment and the inner side of the photovoltaic glass curtain wall, significantly improving its power generation performance. Additionally, on sunny days with relatively high temperatures, the temperature regulation of the photovoltaic glass curtain wall by plants and the enhancement of its power generation performance are even more pronounced.
