Researchers in Spain and Turkey aim at 22%-efficient UMG solar cell

The Cheer-Up project aims to enhance the performance of “Upgraded Metallurgical-Grade (UMG)” silicon for multi-crystalline solar cells and demonstrate it is a competitive alternative to polysilicon by achieving similar efficiencies at lower cost and with less environmental impact. Researchers also want to demonstrate UMG can be used to manufacture the most advanced cell structures.

Part of the European Solar-Era.Net energy technology R&D network, the project is a collaboration between the Madrid-based Instituto de Energía Solar (IES-UPM), Spanish solar company Aurinka PV, the Nanophotonics Technology Center in Valencia and Turkey’s Center for Solar Energy Research and Applications (GÜNAM), in Ankara.
