The effects of epitaxial materials and solar cell design on the performance of solar cells grown by the multilayer approach are investigated. The novel solar cell structure with a p-on-n type configuration suggested exhibits improved uniformity in the photovoltaic performance because of the suppression of Zn diffusion. This approach provides routes to achieve further improvements and acts as a guideline for the commercialization of the multilayer technique.
