Nanophotonic design of perovskite/silicon tandem solar cells

Author affiliations

Abstract

The perovskite material system allows for the realization of perovskite/silicon tandem solar cells with high energy conversion efficiencies at low cost. To realize such solar cells, the device geometry, the device processing, and the contact materials have to be modified in comparison to single junction perovskite solar cells. In this study, perovskite/silicon tandem solar cells are designed allowing for the generation of short-circuit current densities and energy conversion efficiencies exceeding 20 mA cm−2 and 30%, while using realistic device structures. High short-circuit current densities can be achieved by minimizing reflection losses and optical losses of the contact layers. A hybrid approach is used to investigate the optics by combining finite-difference time-domain simulations with experimental measurements. Details on the nanophotonic design will be provided and discussed.
