Cigs Solar Panels

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.

Cigs solar panels.

Of known sellers power range wp avancis. Cigs cells also use the toxic chemical cadmium. Here the light is absorbed and through the photovoltaic effect an electron hole pair is created. The measurement means that.

This efficiency record confirmed by tüv rheinland on a module surface area of 120 x 60 centimeters was achieved on production equipment of manz at the r d site of nice solar energy in schwäbisch hall. It will also be better in grey weather when you need the power the most. 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 absorber the cigs layer in a solar cell is where the action is.

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 objective is to collect that electron before it runs into something and is re absorbed called recombination. Copper indium gallium selenide cigs. 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.

Due to these properties cigs solar chargers are significantly thinner and lighter than solar chargers built from traditional materials. Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels. Here you can see some of the differences on cigs and crystalline solar cells. Company name region no.

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. Companies involved in cis solar panel production a key thin film panel technology. 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.

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. The manufacturing of these solar panels began in germany during 2011 but they are now also made in the united states and china. 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.
