Thin Film Solar Cell (CIGS)
CIGS is a compound semiconductor, Cu(In,Ga)Se₂. The thickness of each individual layer can be measured with an XRF analyzer.
What is CIGS?
Unlike a crystalline solar cell, which uses solid crystalline silicon as its substrate, a thin-film solar cell is a second-generation technology that uses inexpensive glass as the substrate and deposits the silicon material onto its surface as a thin film.
Application of a Thin Film Solar Cell
The structure is a standard glass substrate carrying the thin film, the light-absorbing layer, the buffer layer, the front transparent electrode, and the electrode with its anti-reflective coating.
