Thin film Solar Cell
- Thin film solar cells are made from a variety of materials.
- As the name indicates thin film solar cell are often slimmer than other solar cell types.
- The most prevalent type of thin film solar cell is made from Cadmium telluride(CdTe).
- Manufactures place a layer of CdTe between transparent conducting layers that help capture sunlight.
- Copper indium Gallium Selenide(CIGS) panels are popular type of thin-film technology.
Solar Cell
A Solar Cell is a device that converts light energy into electrical energy using the photovoltaic effect. A solar cell is also known as a photovoltaic cell(PV cell). A solar cell is made up of two types of semiconductors, one is called the p-type silicon layer and the n-type silicon layer. So Solar cell is a p-n junction diode.
The solar energy from the sun in the form of photons creates loose electrons on the n-type semiconductor and holes on the p-type semiconductor. These loose electrons are collected on the aluminum layer and start flowing thus resulting in an electric current.
