Cigs Solar Cell Ppt

Abass thin solid films 535 2013 296 301 the result of measurements performed on cigs based solar cells depends on history of the sample the model includes band gap grading multivalent defects and metastable transitions between defects.

Cigs solar cell ppt.

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. Because the material has a high absorption coefficient. 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. 3 35 on the cell and 17 5 on the module level.

Most enterprises favour the crystalline technology because of former problems. Cdte solar cell withsolar cell with cds window layerwindow layer metal back contact. Advanced electrical simulation of thin film solar cells m. 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.

And ff values 3. Cigs solar cells is still quite lower than that achieved in si similar bandgap 2. Perovskite cigs tandem cells have been pro duced and there. Th in 0 33mm lightweight 7 5 gm ideal for many specialized uses.

The window materials tcos and cds are responsible for the. Low cost figure 2. Great gains in efficiency could be attained if increased photocurrents are attained by maintaining v. As of 2018 cigs cell efficiencies have surpassed all other thin film pv technologies achieving 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. 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. Cigs has also been deployed in ultra high efficiency tandem cells with the potential to achieve 30 efficiency.

Cigs solar cell cigs properties cigs is a i iii vi compound semiconductor material composed of copper indium gallium and selenium. Cigs is one of three mainstream thin film pv technologies the other two being cadmium telluride and amorphous silicon. Anode glass superstrate 1000 um incident light 22 cds. Range noted 2is specific to fully laminated modules presently available with areal density ranging from 310 400 g m.
