Organic solar cells are thought to suffer from poor thermal stability of the active layer nanostructure, a common belief that is based on the extensive work that has been carried out on fullerene-based systems.
Much of the current understanding of processes that limit the thermal stability originates from the extensive work that has been carried out on blends based on fullerene acceptors, which have dominated the field of organic solar cells for a long time.
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.
Illustrated in Fig. 4 is the correlation between solar cell efficiency and temperature. As temperature rises, efficiency experiences a decline attributed to heightened electron–hole recombination rates and alterations in the bandgap properties of materials.
Temperature plays a crucial role in shaping the electrical characteristics of solar cells, impacting both voltage and current output. Regarding voltage, the open-circuit voltage (Voc) diminishes with rising temperatures, influencing the maximum power point voltage (Vmpp).
