Cigs Technology Solar Panels

Although cigs solar cells are considered to be in the early stages of large scale commercialization they can be produced by.

Cigs technology solar panels.

It is best known as the material for cigs solar cells a thin film technology used in the photovoltaic industry. Cigs will start earlier in the morning and stay on for longer in the evening. 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. The hallmark of cis technology is its wafer thin 2µm semiconductor layer.

Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon 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. 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. 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.

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. 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. Cis or cigs refers to the components copper cu indium in gallium ga and selenium se. 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.

Cigs cells also use the toxic chemical cadmium. 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. The benefits of cigs solar cells include. 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 measurement means that. Improvements in efficiency have made cigs an established technology among alternative cell materials. In this role cigs has the advantage of being able to be deposited on flexible substrate materials producing highly flexible lightweight solar panels. 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.

A tunable bandgap allows the possibility of tandem cigs devices.
