Cigs Solar Cell Ppt

Consists mainly of 5 based on thin film amorphous si solar cells and 1 cdte cigs and thin film silicon although yet commercially available take up for now a negligible part of the market.

Cigs solar cell ppt.

And ff values 3. Cigs has also been deployed in ultra high efficiency tandem cells with the potential to achieve 30 efficiency. Advanced electrical simulation of thin film solar cells m. Cathode p type cdte absorber layer 3 8 um transparent conducting oxide window layer n type cds 0 1 um 0 05 um front contact.

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. Perovskite cigs tandem cells have been pro duced and there. Cigs solar cell cigs properties cigs is a i iii vi compound semiconductor material composed of copper indium gallium and selenium. 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.

Tends to be n type large bandgap 2 42ev. Ast s flexible cigs and novel packaging are highly adaptable to various applications thus power density and power to weight ratio can vary significantly with border width etc. 3 35 on the cell and 17 5 on the module level. Like these materials cigs layers are.

Most enterprises favour the crystalline technology because of former problems. Cigs is one of three mainstream thin film pv technologies the other two being cadmium telluride and amorphous silicon. Key features 312 0cell effi ciency level of up to 17 in a fl exible form factor. Because the material has a high absorption coefficient.

Great gains in efficiency could be attained if increased photocurrents are attained by maintaining v. The window materials tcos and cds are responsible for the. Th in 0 33mm lightweight 7 5 gm ideal for many specialized uses. Anode glass superstrate 1000 um incident light 22 cds.

Low cost figure 2. Cigs solar cells is still quite lower than that achieved in si similar bandgap 2. Cigs solar cell miasolé thin film cigs solar cells on stainless steel substrate have high efficiency levels and provide significant advantages over conventional rigid solar cells. The material is a solid solution of copper indium selenide often abbreviated cis and copper gallium selenide with a chemical formula of cuinxga 1 x se2 where the value of x can vary from.
