Cigs Solar Panels

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

Cigs solar panels.

Copper indium gallium selenide cigs. 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. Cigs cells also use the toxic chemical cadmium.

Cigs will start earlier in the morning and stay on for longer in the evening. 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. 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. 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.

The measurement means that. Adding a small amount of gallium g forming cigs boosts the light absorbing band gap which makes it more closely match the solar spectrum thereby improving the voltage and efficiency of the pv cells. The objective is to collect that electron before it runs into something and is re absorbed called recombination. Due to these properties cigs solar chargers are significantly thinner and lighter than solar chargers built from traditional materials.

Company name region no. Here you can see some of the differences on cigs and crystalline solar cells. Of known sellers power range wp avancis. The manufacturing of these solar panels began in germany during 2011 but they are now also made in the united states and china.

German chines joint venture nice solar energy gmbh has achieved a new world record efficiency for cigs thin film solar modules with 17 6 percent. The absorber the cigs layer in a solar cell is where the action is. Thin film solar panels made with a copper indium gallium selenide substrate contain less toxic cadmium than cdte cells. Although cigs solar cells are considered to be in the early stages of large scale commercialization they can be produced by.

Here the light is absorbed and through the photovoltaic effect an electron hole pair is created. Companies involved in cis solar panel production a key thin film panel technology. 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.
