What is the conversion efficiency of a single crystal silicon (Si) solar cell?
Currently single crystal silicon (Si) solar cell exhibits a conversion efficiency of about 25% and has dominated the solar cell market. However, due to low light absorption and indirect bandgap features, single crystal Si layers of around 200–250 µm in thickness are usually needed to efficiently harvest the sunlight.
Are thin film solar cells a viable alternative to silicon photovoltaics?
As an alternative to single crystal silicon photovoltaics, thin film solar cells have been extensively explored for miniaturized cost-effective photovoltaic systems. Though the fight to gain efficiency has been severely engaged over the years, the battle is not yet over.

Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or TFs) of photovoltaic 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 wafers used in conventional crystalline silicon (c-Si) based solar cells, which can be up to 200 μm thick.
