A bifacial solar cell (BSC) is a photovoltaic that can produce electrical energy from both front and rear side. In contrast, monofacial solar cells produce electrical energy only when photons are incident on their front side. Bifacial solar cells and (devices that consist of multiple solar cells) can improve the electric energy output and modify the temporal power production profile co.

Thin-film solar cells are a type of made by depositing one or more thin layers ( or TFs) of material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers () to a few microns () thick–much thinner than the used in conventional (c-Si) based solar cells, which can be up to 200 μm thick.
