High-throughput calculations for the identification of novel materials for tandem cells — •Hossein Mirhosseini, Ramya Kormath Raghupathy, Hendrik Wiebeler, and Thomas D. Kühne — Department of Chemistry, University of Paderborn, Paderborn, Germany

One straightforward way to considerably enhance the efficiency of the solar cells is the realization of multi-junction solar cells such as tandem cells: the efficiency of a two sub-cells tandem can be raised up to 42% [1]. In this work, high-throughput ab-initio calculations were employed to identify the most promising absorber and p-type transparent conducting materials (TCMs) for future tandem cells [2]. Non-toxic semiconductors with hole effective masses smaller than 1 and band gaps larger than 1 eV (for absorber) and 1.7 eV (for TCMs) were considered here. The dopability and extrinsic dopants were investigated to determine the performance of the selected compounds.
