BARRIER TYPE PHOTOVOLTAIC CELLS WITH ENHANCED OPEN-CIRCUIT VOLTAGE, AND PROCESS OF MANUFACTURE

摘要

BARRIER TYPE PHOTOVOLTAIC CELLS WITH ENHANCED OPEN-CIRCUIT VOLTAGE, AND PROCESS AND MANUFACTURE A cadmium telluride photovoltaic cell is produced with increased conversion efficiency arising from enhanced open-circuit voltage. Such voltage is achieved by altering the surface of the crystalline cadmium telluride that contacts the barrier metal by heating the cadmium telluride in the presence of oxygen prior to depositing the barrier metal.
