Cigs Solar Panel Efficiency

However commercial cigs cells have lower efficiencies with most modules attaining about 14 percent conversion.

Cigs solar panel efficiency.

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. Record efficiency of up to 15 5 on 30 30 cm2 and 13 9 on 1 m2 sized fully integrated thin film solar modules have been achieved at avancis using rapid thermal annealing of stacked elemental layers of cu ga in and se. While it trails in efficiency cigs is not far away has shown a cigs solar cell that converts 19 5 percent of sunlight into electricity. Thin panel solar panels made with gallium arsenide are considered the most efficient of all thin panels with a high of 28 8 percent.

Cigs is a versatile material that can be fabricated by multiple processes and implemented in different form factors. In a manufacturing environment that means 15 percent to 16. Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels. Cigs offers the highest efficiency of thin film pv technologies cigs offers the highest energy yield at different light conditions cigs offers low environmental impact and sustainability flexible module materials offer low weight per area roof kg m2 and low weight per power generated kg w.

Cigs cells also use the toxic chemical cadmium. That makes it the most efficient. Cigs panels have shown potential in laboratory testing for high efficiency put in real world use they have shown an efficiency of 10 12 percent. In september 2012 the german manz ag presented a cigs solar module with an efficiency of 14 6 on total module surface and 15 9 on aperture which was produced on a mass production facility.

The efficiency of the solar cells used in a photovoltaic system in combination with latitude and climate determines the annual energy output of the system for example a solar panel with 20 efficiency and an area of 1 m 2 will produce 200. Miasolé obtained a certified 15 7 aperture area efficiency on a 1m 2 production module and solar frontier claimed a 17 8 efficiency on a 900 cm 2 module. In 2014 laboratory experiments produced a record efficiency of 23 2 percent by a cigs cell with a modified surface structure. Solar cell efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell.

Cigs based thin film solar modules represent a high efficiency alternative for large scale commercial solar modules.
