Thin film solar panel: Most suitable for applications with large rooftops or wide open spaces
What are Thin-Film Solar Panels?
A thin-film solar panel is made up of an assembly of thin-film solar cells. These solar panels convert solar energy to electrical energy by using the principle of the photovoltaic effect. Each thin-film solar cell is made up of several layers of photon-absorbing materials. These layers can be up to 300 – 350 times smaller than the layers of standard silicon panels.
These solar panels are categorized on the basis of the material that is used as a substrate in them. Materials such as Amorphous Silicon (a-Si), Copper Indium Gallium Selenide (CIGS), Cadmium Telluride (CdTe), and Gallium Arsenide (GaAs) are used as substrates. Out of these, thin-film solar panels with a GaAs substrate are the most efficient, about 28.8% more than others.
