The Fraunhofer Institute for Solar Energy (ISE) has claimed a new record conversion efficiency for a both-sides contacted silicon solar cell of 26%.
Furthermore, Fraunhofer ISE has said the technology used to achieve the record – wherein both sides, front and rear, have metal contacts – holds the potential to push efficiencies up to 27%.
A team of researchers led by Fraunhofer ISE’s Dr. Armin Richter used Tunnel Oxide Passivating Contact (TOPCon) technology as a basis for the cell’s structure, which the research institute said possessed advantages of low surface recombination losses and efficient charge carrier transport over interdigitated back contact (IBC) cells.
