Working principle of solar cell.
Cigs solar cell in full copper indium gallium selenide solar cell thin film photovoltaic device that uses semiconductor layers of copper indium gallium selenide cigs to absorb sunlight and convert it into electricity although cigs solar cells are considered to be in the early stages of large scale commercialization they can be produced by using a process that has the potential to reduce.
The energy obtained from the sun directly into the electrical energy.
A copper indium gallium selenide solar cell or cigs cell sometimes ci g s or cis cell is a thin film solar cell used to convert sunlight into electric power.
Solar cell is a device or a structure that converts the solar energy i e.
Cigs cells have up to 10 efficiency with similar durability as silicon solar cells.
Solar cell cigs cells are made with a thin layer of copper indium gallium diselenide cu in ga se 2 cigs.
Thin film solar cells 15m.
When light reaches the p n junction the light photons can easily enter in the junction through very thin p type layer the light energy in the form of photons supplies sufficient energy to the junction to create a number of electron hole pairs.
Since they are a thin film technology they can be less costly than si cells.
