基于真实环境下染料敏化太阳电池组件的理论研究与性能模拟

In the more than two decades, the researches of dye sensitized solar cells (DSC) have obtained exciting achievement on lab-small areas by many groups. Photoelectrical conversion efficiency 13% has been obtained, which indicates that DSC has good prospects for commercial application. Therefore, industrialized research will be an important aspect for DSC researches in the future. The urgent key question is how to clarify the impact of various environmental factors on the performance of DSC modules and further improve the output power in a real environment by designing a reasonable module structure. Based on persent study and combined with the theoretical simulation and experiment research, this project starts from the light receiving, heat transport and charge collection of DSC modules to investigate the influence mechanism of environmental change on photovoltaic performance of DSC modules. The change law of photovoltaic performance is explored with the different structure of DSC modules. The combined optical, thermal and electrical model of DSC modules is also established. This project analyzes the relationship of light loss, heat loss and electrical loss, and discloses the energy loss mechanism of DSC modules. We are eager to get the optimal structure of DSC modules and improve the photovoltaic performance of DSC modules in real environment through the study of the project.
