Simultaneous enhanced efficiency and thermal stability in organic solar cells from a polymer acceptor additive | Nature …
Thermal instability is a critical bottleneck for bulk heterojunction organic solar cells. Here Yang et al. use barely 1 wt% of a polymer acceptor as an additive to simultaneously improve the ...
Optical Losses
Anti-reflection coatings can be used on the top surface of the cell. Reflection can be reduced by surface texturing. The solar cell can be made thicker to increase absorption (although light that is absorbed more than a diffusion length from the junction has a low collection probability and will not contribute to the short circuit current).
Neutral-colored transparent solar cells with radiative ...
Lee et al. show that applying a microscale inverted-pyramidal-structured polydimethylsiloxane (MIPS-PDMS) film to selected areas of transparent crystalline silicon solar cells enhances light absorption, mitigates angle-dependent efficiency reduction, and reduces the temperature increase of the device. These improvements are attributed to …
Optical Losses
Optical losses consist of light which could have generated an electron-hole pair, but does not, because the light is reflected from the front surface, or because it is not absorbed in the solar cell. For the most common semiconductor solar cells, the entire visible spectrum (350 - 780 nm) has enough energy to create electron-hole pairs and therefore all visible light …

Reducing Operating Temperature in Photovoltaic Modules
As many common photovoltaic cells, including c-Si, CdTe, and CIGS, decrease in efficiency with increasing temperature, a more effective coating would increase reflection of sub-bandgap light while still acting as an antireflection coating for higher energy photons.
