Abstract

We present the results of a series of numerical study of a-Si:H solar cells on different V- grooved substrates. The light absorption profiles were calculated by taking into account the V-groove inner reflection and the reflection at the glass/air interface. These profiles were used for modeling the performance of solar cells with the 1-D Amorphous Semiconductor Analysis (ASA) computer package, which has been developed in our laboratory. The J-V characteristics under AMI.5 and the external quantum efficiency axe simulated for V- grooves with different tilt-angles (0 degree for flat substrate). Results show that effective light trapping occurs for V-grooves with tilt-angle larger than 21 degrees.
