Key features 312 0cell effi ciency level of up to 17 in a fl exible form factor. 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.

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. Cigs solar cell cigs properties cigs is a i iii vi compound semiconductor material composed of copper indium gallium and selenium. And ff values 3. Cigs is one of three mainstream thin film pv technologies the other two being cadmium telluride and amorphous silicon.

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. Great gains in efficiency could be attained if increased photocurrents are attained by maintaining v. Cigs has also been deployed in ultra high efficiency tandem cells with the potential to achieve 30 efficiency. Tends to be n type large bandgap 2 42ev.

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. As of 2018 cigs cell efficiencies have surpassed all other thin film pv technologies achieving 2. Most enterprises favour the crystalline technology because of former problems. 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.
