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.
Cigs solar panels.
These advantages include high conversion efficiency low costs of manufacturing the ability to fully utilize a wide range of wavelengths of sun light and therefore retain efficacy in overcast conditions and.
Cigs is a versatile material that can be fabricated by multiple processes and implemented in different form factors.
Cigs will start earlier in the morning and stay on for longer in the evening.
Because the material has a high absorption coefficient.
Cigs based thin film solar modules represent a high efficiency alternative for large scale commercial solar modules.
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.
Advantages and disadvantages of cigs solar panels.
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.
For example cigs can be deposited on substrates such as glass metal foils and polymers.
The measurement means that.
The manufacturing of these solar panels began in germany during 2011 but they are now also made in the united states and china.
Thin film solar panels made with a copper indium gallium selenide substrate contain less toxic cadmium than cdte cells.
Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels.
Cigs is the only technology that offers this promise.
Copper indium gallium selenide cigs.
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.
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.
The differences between cigs and crystalline solar cells.
Just recently polycrystalline cigs achieved higher efficiencies than polycrystalline silicon with a world record of 20 8 compared to 20 4 for silicon.
