Toshiba Raises the Power Conversion Efficiency of Transparent Cu2O Solar Cell to 8.4%

Toshiba Corporation today announced that it has successfully raised the power conversion efficiency (PCE) of its transparent Cu2O solar cell to 8.4%, the world's highest level for a reported Cu2O solar cell. With the cell positioned as the top cell over a 25% PCE silicon cell (Cu2O-Si tandem cell), Toshiba estimates that an overall PCE of 27.4% can be achieved, notably above the 26.7% highest PCE reported for any standard silicon cell.
