The performance of most high-efficiency silicon solar cells is dominated by recombination in oxide-passivated emitters on the cell surface. To quantify the properties of passivated emitters, measurements of the emitter saturation current density, ;From ;Finally, the implications of this new information for the design of high-efficiency, silicon solar cells will be discussed. Several types of backside-contact, one-sun cells were fabricated and optimized with the help of this data, and have demonstrated efficiencies up to 22.7% on cells with 37.5 cm... |
