Power Generation Performance of Distributed Photovoltaic Systems Based on Perovskite Solar Cells

Distributed photovoltaic systems are one of the key technologies for achieving China's carbon peaking and carbon neutrality goals, with their continuous development and technological progress being crucial. This study focuses on six representative cities in China, comparing and analyzing the power generation performance of rooftop distributed photovoltaic systems based on perovskite solar cells against those using traditional silicon solar cells. The research found that in all the cities examined, photovoltaic systems employing perovskite solar cells demonstrated higher efficiency compared to systems based on silicon solar cells, with efficiency improvement ranging between 7.0% and 9.9%, especially notable in Haikou and Chongqing with higher annual average temperature or lower light irradiance. This performance advantage mainly stems from the low temperature coefficient and superior performance under low-intensity light irradiance of perovskite solar cells. Additionally, the power generation performance of perovskite cells exhibits lower sensitivity to weather changes, contributing to the overall stability of photovoltaic systems. The widespread application of perovskite photovoltaic technology is expected to further enhance the efficiency and stability of China's distributed photovoltaic systems, providing valuable technical support for China's energy transition.
