Cigs Solar Panel Efficiency

For example cigs can be deposited on substrates such as glass metal foils and polymers.

Cigs solar panel efficiency. That makes it the most efficient. Cigs cells also use the toxic chemical cadmium. However because of their cost they are typically used in building spacecrafts and other types of specialized applications where pv energy is required. However commercial cigs cells have lower efficiencies with most modules attaining about 14 percent conversion.

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. In a manufacturing environment that means 15 percent to 16. 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 top honor was claimed by researchers at the national renewable energy laboratory nrel who have developed a new solar cell with an efficiency of 47 1 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. 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. 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.

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 2014 laboratory experiments produced a record efficiency of 23 2 percent by a cigs cell with a modified surface structure. 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.

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