Losses in solar cells can result from a variety of physical and electrical processes, which have an impact on the system's overall functionality and power conversion efficiency. These losses may happen during the solar cell's light absorption, charge creation, charge collecting, and electrical output processes, among others.
Over the last four decades, the costs of solar energy products — in particular, solar photovoltaic modules — have dropped by 99%. That is quite a dramatic drop, and it’s even more dramatic to know that the costs we have right now will continue to fall in the years to come.
Loss processes in solar cells consist of two parts: intrinsic losses (fundamental losses) and extrinsic losses. Intrinsic losses are unavoidable in single bandgap solar cells, even if in the idealized solar cells .
The external radiative efficiency, solid angle of absorption (e.g., the concentrator photovoltaic system), series resistance and operating temperature are demonstrated to greatly affect the loss processes. Furthermore, based on the calculated thermal equilibrium states, the temperature coefficients of solar cells versus the bandgap Eg are plotted.
