6 FAQs about [Normal loss of photovoltaic cell components]

What is loss process in solar cells?

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 .

What factors affect loss processes in photovoltaic devices?

This paper studies the loss processes in photovoltaic devices depending on different kinds of parameters, such as external radiative efficiency (ERE), solid angle of absorption, resistances and operating temperature.

What are extrinsic losses in single bandgap solar cells?

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 .

How do cell parameters affect photovoltaic loss processes?

Considering that the parameters of the cells greatly affect the loss processes in photovoltaic devices, the sensitivities of loss processes to structure parameters (e.g., external radiative efficiency, solid angle of absorption, resistances, etc.) and operating parameters (e.g., operating temperature) are studied.

What are solar cell losses?

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).

Why do solar cells lose energy?

For solar cells with bandgap Eg varying from 1 eV to 3 eV, we can see the main energy losses consist of the below Eg loss, the thermalization loss and the angle mismatch loss. And all these three kinds of losses contribute to heat generation, causing a significant temperature rise, which greatly limits the efficiency of solar cells.
