Tandem solar cells that pair silicon with a metal halide perovskite are promising option for surpassing the single-cell efficiency limit. We report monolithic perovskite/silicon tandem certified power conversion of 29.15%. The absorber, bandgap 1.68 electron volts, remained phase-stable under illumination through combination fast hole extraction and minimized nonradiative recombination at hole-selective interface. These features were made possible by self-assembled, methyl-substituted carbazole monolayer as layer in cell. accelerated was linked to low ideality factor 1.26 single-junction fill factors up 84%, while enabling open-circuit voltage high 1.92 volts. In air, without encapsulation, retained 95% its initial after 300 hours operation.

Abstract The last decade has seen remarkable advancements in the field of perovskite materials and photovoltaic technologies. One their most extraordinary characteristics is high quality layers that can be obtained by “dirty processing” from solution at low temperatures. Alternatively, perovskites also deposited thermal evaporation, a clean, solvent‐free process, which well established for many industrial applications. Although vast majority research reports focus on solution‐processing as deposition method solar cells, thermally evaporated cells are closing performance gap with several efficiencies above 20%. In this Progress Report, two methods briefly introduced, key developments devices based each technique outlined, challenges future possibilities discussed.
