Solution-based semiconductors are a promising new material class in thin-film electronics. So far, the quality of the device made of such material has been rather poor. Here, solar cells made of solution-based silicon with an efficiency of 3.5%, exceeding previous results by a factor of seven, are reported. This may pave the way for development of industrial applications.
