Title: The dependence of the open-circuit voltage of silicon solar cells on emitter surface parameters
Abstract: Three types of solar cells were fabricated: n+−p cells and high efficiency n+−p−p+ and p+−n−n+ back-surface field cells. The only variable parameter was the surface condition on the emitter side: either the surface treatment after metallization or the front (emitter surface) metal coverage factor α. The influence of these surface conditions on the saturation current I0 and hence on Voc was determined. It was concluded that in the back-surfce field cells the saturation current density J0 due to the injection of minority carriers into the emitter was of the same order of magnitude as the bulk injection component. It was also concluded that the emitter is transparent to minority carriers.
