Back-contacted, ultrathin (<10 µm), and submillimeter-sized solar cells made with microsystem tools are a new type of cell that has not been optimized for performance. In this paper, we present the design conditions and fabrication parameters necessary to optimize these devices via simulations. Through completing the simulations, an optimized concept solar cell design was introduced for two scenarios: high and low quality materials/passivation. Simulated efficiencies up to 23.4% (1 sun) and 26.7% (100 suns) were attained for 20-µm-thick devices.
