It is clear that optical losses are responsible for both solar radiation reduction by shadowing light and reflection and inadequate absorption of long wavelength radiation [7]. Therefore electrical losses have a negative effect on both the voltage and current of the solar cell. The final types of losses depend on semiconductor physics and ...

The efficiency that a solar cell can reach is ultimately limited by the number of photons absorbed in its active layer. Bulk heterojunction polymer solar cells are fabricated from a stack of thin film layers, each of which is thinner than a single wavelength from an incident photon within its absorption band. One consequence of this thin film …
Optical loss of solar cells can be reduced by adjusting the design parameters of patterns, including the size, shape, and materials.
