Jason-125RoseStreet Labs Energy (RSLE) has created what they assert to be the world’s first tandem nitride/silicon solar cell. RSLE combined a silicon solar cell with a Nitride Thin Film to create their hybrid photovoltaic cell. According to RSLE, this hybrid will achieve “practical efficiencies” of 25-30% (typical efficiencies range from 12-20%).

Bob Forcier, CEO, of RSLE, stated, “We are quite excited about this new Hybrid solar cell that marries low cost Nitride thin film with the massive infrastructure of silicon solar cells. Our target market for this Hybrid device is the high performance sector for photovoltaics which we estimate to be over 1% of the $34B solar cell global market.”

Certain questions remain—will RSLE’s discovery be cost-prohibitive to consumers? Or will it help push photovoltaics into the mainstream? RSLE will start production on their tandem solar cells in Q4 2010.
