Cigs Technology Solar Panels

Improvements in efficiency have made cigs an established technology among alternative cell materials.

Cigs technology solar panels.

Cigs solar cell thin film photovoltaic device that uses semiconductor layers of copper indium gallium selenide cigs to absorb sunlight and convert it into electricity. Cigs will start earlier in the morning and stay on for longer in the evening. The hallmark of cis technology is its wafer thin 2µm semiconductor layer. One big difference is that the cigs is more light sensitive and therefore will a 100 watt peak cigs panel produce around 10 15 more power in a year than a 100 watt peak crystaline panel.

Cis is the most efficient thin film technology in terms of energy yield kwh kwp our modules have some of the highest yields of any photovoltaic system. Cigs cells also use the toxic chemical cadmium. Building integrated photovoltaics as the name suggests seamlessly blend into building architecture in the form of roofs canopies curtain walls facades and skylight systems unlike traditional solar pv panels bipv can be aesthetically appealing rather than a compromise to a building s design. With efficiencies exceeding 20 measured in the laboratory there may be a continuing place for high efficiency cigs panels in the general solar panel market.

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. Global solar energy s factory is located in tucson arizona and produces flexible solar cells based on our proprietary cigs thin film processes innovative interconnect technology and module structures. The benefits of cigs solar cells include. 2 bipv solar technology.

Tucson arizona usa. A tunable bandgap allows the possibility of tandem cigs devices. It is best known as the material for cigs solar cells a thin film technology used in the photovoltaic industry. David pearce ceo of cigs manufacturer miasole says that his company can erect a factory that can put out 100 megawatts worth of solar panels a year for 25 million.

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. In this role cigs has the advantage of being able to be deposited on flexible substrate materials producing highly flexible lightweight solar panels. Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels. Cis or cigs refers to the components copper cu indium in gallium ga and selenium se.

This direct bandgap material can absorb a significant portion of the solar spectrum enabling it to achieve the highest efficiency of any thin film technology.
