Researchers from TNO, Imec and Eindhoven University of Technology, partners in the Netherlands-based Solliance research consortium, have developed a transparent perovskite solar cell with near-infrared efficiency of 18.6 percent. Combined with a crystalline silicon (c-Si) cell from Panasonic or a flexible CIGS (copper indium gallium diselenide) cell from Miasolé, record efficiencies of 28.7 percent and 27.0 percent were achieved.
According to Solliance, the perovskite solar cell was combined with different solar cells and different cell technologies, with results reportedly yielding improvements of more than 1.5 percent over previous efficiencies achieved at Solliance. They »form the basis for the next phase of development along with upscaling,« said Mehrdad Najafi of the Dutch research organization TNO. Solliance Solar Research is a partnership of research institutes and universities from the Netherlands, Belgium and Germany working in the field of thin-film photovoltaics.
