Semitransparent perovskite-based solar cells (ST-PSCs) are highly desired to be integrated into buildings as electricity-generating solar windows in the context of Building-Integrated Photovoltaics (BIPVs), as well as in tandem solar cells combined with other low-bandgap solar cells (e.g. silicon or CIGS) to give enhanced light-harvesting. To fabricate high-performance ST-PSCs, one key challenge is that of replacing the conventional opaque metal top electrodes with suitable transparent alternatives. Recently, dielectric/metal/dielectric (DMD) multilayer architectures have been shown to be suitable candidates as transparent top electrodes, exhibiting ideal characteristics such as mechanical and thermal stability, low deposition temperatures, and tunable opto-electrical properties.3 Here, semitransparent mixed-halide perovskite planar solar cells with thermally evaporated DMD top electrodes (MoOx/Au (or Au/Cu)/MoOx) have been successfully fabricated. The top Au-based ST solar cell exhibited a PCE of 13% (opaque reference gave 14.2%) with average transmittances of 6% in the range 400-800 nm and 38% in the range 800-1000 nm. Cu-based ST-PSCs showed also impressive performances with a maximum PCE of 12.5% and average transmittances comparable to those of the Au-based devices. References  M. L. Petrus et al. Adv.
