Cigs Solar Cell Review

In this review article working mechanism of cigs solar cell with back surface field and importance of developing cigs solar cells its limitation in commercialization are discussed.

Cigs solar cell review.

Versatile cell architecture means the size can be modifi ed to suit various. Copper indium gallium selenide cigs based solar cells are receiving worldwide attention for solar power generation. It is manufactured by depositing a thin layer of copper indium gallium and selenium on glass or plastic backing along with electrodes on the front and back to collect current. Abstract copper indium gallium selenide cigs based solar cells are receiving worldwide attention for solar power generation.

In this paper the evolution of each technology is discussed in both laboratory and commercial settings and market share and reliability are equally explored. 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. Because the material has a high absorption coefficient. Moreover cigs thin film solar cell has very high potential to overcome the cost level of conventional pv crystalline silicon c si technology the c si modules with efficiencies of 19 23 will have a production cost of 0 6 0 7 wp whereas for cigs modules manufacturing cost of 0 75 wp can be achieved at 50 mw yr production capacity with an average efficiency of 12.

Cigs solar cells are made from a compound called copper gallium indium diselenide sandwiched between conductive layers. The three major thin film solar cell technologies include amorphous silicon α si copper indium gallium selenide cigs and cadmium telluride cdte. This material can be deposited on substrates such as glass plastic steel and aluminum and when deposited on a flexible backing the layers are thin enough to be allow full panel flexibility. They are efficient thin film solar cells that have achieved 22 8 efficiency comparable to crystalline silicon c si wafer based solar cells.

Chalcopyrite cu in ga se 2 cigs based solar cells are promising and widely used solar cells because of their remarkable efficiency low cost and easy integration noufi and zweibel 2006 ramanujam and singh 2017 this is related to their tunable bandgap of approximately 1 0 1 12 ev and high absorption coefficient up to 10 5 cm 1 guillemoles 2002 noufi and. It is an efficient thin film solar cell achieved the 22 8 efficiency. Th in 0 33mm lightweight 7 5 gm ideal for many specialized uses. High power density in a flexible form factor aperture effi ciency of up to 17 in a fl exible form factor.
