A scientific group from two U.S.-based universities has discovered how to transfer the energy between the molecules of silicon and organic material. So far, this phenomenon was only theoretical. The discovery has vast prospects for medical, solar power, and quantum computing applications.

Researchers from the Ulsan Institute of Science and Technology have demonstrated a new method of fabricating perovskite-on-silicon tandem devices, using a transparent conductive adhesive to combine the two cells. The scientists have developed devices with demonstrated efficiencies of 19.4%, and propose strategies to bring that above 24% using existing technology.

The solar industry must work together to agree on standardised larger wafer sizes, according to monocrystalline solar manufacturer LONGi Group.

Chinese thin film producer Hanergy has set a new record of 24.85% module efficiency for silicon heterojunction technology. The record was achieved at the company’s research & development center in Chengdu, China, and has been confirmed by the Institute for Solar Energy Research in Hamelin, Germany.
