What are the root causes of heating in solar cells and modules?
Root causes of heating in solar cells and modules aside from conversion of sunlight to electricity are investigated in an opto-electronically coupled thermal model. All solar cells generate and dissipate heat, thereby increasing the module temperature above the environment temperature.
Is heat generation important in c-Si solar cells and modules?
Heat generation is significant in c-Si solar cells and modules due to its impact on module power output and lifetime. Given this importance, a study of the fundamentals of heat generation within c-Si solar cells and modules is timely, as high temperature and high insolation locations are attractive markets for PV deployment.
How do solar cells generate heat?
As solar cells operate, they invariably generate heat. This heat can originate from multiple sources, including the absorbed sunlight, resistive losses in the cell's electrical contacts, and even environmental factors.
What are thermal effects in solar cells?
Thermal effects in the context of solar cells refer to the changes in their electrical and optical properties due to variations in temperature. As solar cells operate, they invariably generate heat.
