Switzerland-based scientists have designed “ultra-stable” printable solar cells that delivered a constant 11.2% efficiency for over 10,000 hours. Scientists engineered 2D/3D hybrid solar cells which combine the stability of 2D perovskites (usually made of lead) with the 3D form’s efficiency of absorbing light. The breakthrough could lead to cheaper alternatives to the silica-based solar cells.
New solar cells work for 10,000 hours with same efficiency
