Learn MoreLoss 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 .
These losses may happen during the solar cell's light absorption, charge creation, charge collecting, and electrical output processes, among others. Two types of solar cell losses can be distinguished: intrinsic and extrinsic losses (Hirst and Ekins-Daukes, 2011).
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 .

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.
The typical loss of incident light from reflection from a silicon solar cell's front surface is 30%, which lowers the efficiency of the device's total power conversion (Wang et al., 2017). The reflection loss can be expressed as Equation 13. 5.2.2. Parasitic absorption
