Second generation thin film solar cells

Introduction
2
Solar cells are designed to convert solar energy into electrical energy.

Second generation thin film solar cells
3
Thin film solar cells are introduced and developed as the second generation of solar cells to provide high production capacity at lower energy and material consumption

4
This type of solar cell is made on cheap, large area such as glass, metal foil or plastic.

The absorber materials
amorphous silicon
cadmium telluride
copper-indium-gallium-diselenide
(a-Si)
(CdTe)
(CIGS)
In 1976, three separate research groups had formed the thin-film cell. Each group had used different absorber materials.

CIGS cell structure
Copper-indium-gallium-diselenide (CIGS) thin-film solar cells are multilayer thin film devices with nanocrystalline bulk semiconductor as the absorber material.
