AI Customer ServiceLoss 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 losses of a solar cell can be divided into three categories: 1. 2. 3. Ohmic losses. In this chapter, we cover the basics of optical losses and recombination losses. Ohmic losses occur mainly when individual solar cells are assembled into entire modules; they will find application in Chaps. 9 and 10.
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.
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.
Dominant losses and parameters of affecting the solar cell efficiency are discussed. Non-radiative recombination loss is remarkable in high-concentration-ratio solar cells. Series resistance plays a key role in limiting non-radiative recombination loss.
Besides the intrinsic losses, extrinsic losses, such as non-radiative recombination (NRR) loss, series resistance (Rse) loss, shunt resistance (Rsh) loss and parasitic absorption loss [12, 15], also play a very important role in loss processes in single bandgap solar cells. Different from intrinsic losses, they are avoidable .
