Our partners in the Baldo group at MIT have published their recent work in silicon solar cells that demonstrate the possibility of singlet exciton fission. “Key to their achievement was an interface that transfers the electrons and holes sequentially into silicon instead of both at once.”
By sequentially transferring electrons and holes into silicon, their novel, fabricated interface achieves a device that has increased efficiency via this quantum mechanical process.
“Up to now, we have only had indirect evidence that is possible to couple singlet exciton fission to silicon,” the research’s corresponding author, Marc A. Baldo, told pv magazine. “The breakthrough for us was to design an interface that transfers the electrons and holes sequentially into silicon instead of both at once.”
