Flexible CIGS solar cell is claiming to be world record holder for high efficiency solar cells that obtain 18.7 percent efficiency utilizing flexible copper indium gallium (di)selenide on plastics.

These flexible CIGS solar cells have the capability to decrease the price of solar electricity as green means of power to more affordable level as well as bringing solar technology to the optimum levels by its crystalline silicon and rigid CIGS cells.


“The new record value for flexible CIGS solar cells of 18.7% nearly closes the “efficiency gap” to solar cells based on polycrystalline silicon (Si) wafers or CIGS thin film cells on glass”, says Ayodhya N. Tiwari, who heads-up the research team at the Swiss Federal Laboratories for Materials Science and Technology (Empa) Thin Film and Photovoltaics lab.

This also remarks polymer films to be superior than metal foils that were used on conventional solar cells composition to offer above 16 percent efficiency. Also mentioned, FLISOM is going to be the start up company that will bring Flexible CIGS solar cell to the market.
