Solar thin film power generation ppt

What is a thin film solar cell?

44 Thin Film Solar Cells Typical thin-film amorphous silicon construction. Thin-film solar cells are manufactured by applying thin layers of semiconductor materials to a solid backing material. Sunlight entering the intrinsic layer generates free electrons. The p- and n-type layers create an electric field across the intrinsic layer.

Are thin film solar cells made from amorphous silicon?

Different cell types like single crystal, polycrystalline, and amorphous thin films are fabricated through various processes to optimize these factors and harness solar energy on a large scale. The document discusses thin film solar cells made from amorphous silicon and other materials.

Can thin-film solar cells produce cheaper devices on a large scale?

Thin-film solar cell technologies have the potential for producing cheaper devices on a large scale. I-V characteristics of the analyzed solar cells with h= 3:5%, 6.0%, 6.7% & 9.7%. The illumination was performed using an AM1.5 solar simulator.

What materials are used for thin film PV cells?

The materials that have been used for thin film PV cells: a-Si:H, GaAs, CuInSe2, CdTe and TiO2. Tin oxide is a conductive material that is transparent when in a thin layer. Tin oxide is used in place of a metallic grid for the top layer of thin film PV sheets.

How did solar power technology change in the 1960s?

In the 1960s, the space program continued to demand improved PV power generation technology. A typical PV cell consists of semiconductor material having a p-n junction. Sunlight striking the cell raises the energy level of electrons and frees them from their atomic shells.
