REC to collaborate with Fraunhofer ISE on the development of high-efficiency solar cells

REC is teaming up with the Fraunhofer Institute for Solar Energy Systems ISE to develop high-efficiency solar cells based on n-type monocrystalline wafers.

n-Type solar cells have a higher efficiency potential than traditional p-type solar cells. Moreover, they do not display the light induced degradation that conventional p-type solar cells suffer from. However, n-type cells are more complex to manufacture and traditionally require expensive silver contacts on both sides of the cell.

Fraunhofer ISE has now developed a high-efficiency cell structure that avoids the use of an expensive silver contact grid on the back of the cell. Instead, this cell structure makes use of a combination of dielectric layers and localized contacts. REC, which has a vast experience in the development and optimization state-of-the-art manufacturing processes, will work together with Fraunhofer ISE to translate this technology from lab scale to a full production-ready concept. The new production process is expected to yield high-efficiency cells at competitive costs on proven production equipment. The latter will make it possible to implement this technology quickly in production once it is fully developed.
