Scientists at Oxford PV have developed a tandem solar cell with a power conversion efficiency of 25.2%, with the possibility of achieving more than 30%. According to a study in the journal Nature Materials, the team covered the silicon "pyramids" of a solar cell with an inorganic base layer, which was then covered with an organic perovskite compound, eliminating the need for costly smoothing of the surface. The team said more work needed to be done to improve the cell's stability ahead of commercialisation.
