Influence of wavelength on the performance of a Vertical-Junction Photocell

This article presents an in-depth analysis of the influence of the wavelength of monochromatic illumination on the electrical behavior of a vertical-junction series-connected photocell. Based on the modelling and simulation of characteristic quantities such as the photocurrent density, the photovoltage and the maximum power, we highlight the effects of spectral absorption and the carrier generation depth. The results show that the variation of the wavelength has a strong impact on charge collection and on the overall performance of the cell.
