Fraunhofer Develops New, Easy to Make High Efficiency Solar Cells

Yet another efficiency record has been established for mass-producible solar cells: 23.4%. The Fraunhofer Institute for Solar Energy Systems (ISE) from Germany succeeded to manufacture a single-crystal silicon solar cell of a thin p-type semiconductor layer residing on an n-type semiconductor substrate. The solar cell’s area is 2x2cm.
