Description
Summary:A new model of the photocarrier generation rate of regularly textured silicon solar cells with microgrooves and pyramids on the front surface for application to numerical simulation has been described. The photocarrier generation rate has been formulated based on an analytical approach by considering carefully all the optical paths of the incident light into the cells. This model can be simply incorporated into the device simulation program. The two-dimensionally simulated performance parameters of the sample textured solar cells are in considerable agreement with the previously measured results.
