CEA-Ines achieves 19.2% efficiency for flexible perovskite solar cell
The cell was fabricated with a flexible substrate made of indium tin oxide (ITO) and polyethylene terephthalate (PET). The device was tested through a damp heat test and showed it can retain around 90% of its initial efficiency after 800 hours.Researchers at France's National Solar Energy Institute (INES) - an arm of the French Alternative Energies and Atomic Energy Commission (CEA) -have developed a perovskite solar cell on a flexible substrate with an efficiency of 19.2%. The scientists explained that the same cell had achieved an efficiency of 20.2% for a cell with a size of 11cm2 based on ...
