Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
A review of primary technologies of thin-film solar cells
The thickness of the film can vary from several nanometers to tens of micrometers, which is noticeably thinner than its opponent, the traditional 1st generation c-Si solar cell (∼200 μm thick wafers). This is why thin-film solar cells are amenable, lower in mass, and have limited resistance or abrasion [8–10]. 2.1. Amorphous silicon solar cell
High efficiency thin-film amorphous silicon solar cells
Enhancing light absorption within thin film amorphous silicon (a-Si) solar cells should lead to higher efficiency. This improvement is typically done using various …
