Thin-film photovoltaics play an important role in the quest for clean renewable energy. Recently, methylammonium lead halide perovskites were identified as promising absorbers for solar cells.1 In the three years since, the performance of perovskite-based solar cells has improved rapidly to reach efficiencies as high as 15%.2-5 We developed metal oxide free methylammonium lead iodide perovskite cells with high power-conversion efficiencies.6 The effect of the organic charge transporting layers on the performance of these solar cells will be presented as well as the effect of different layer thicknesses. The power conversion efficiency increases from 4.7 % for a device with only an organic hole transporting/electron blocking layer to 12 % when the perovskite layer is sandwiched in between suitable organic electron and hole blocking layers. We will present recent developments in these metal oxide free perovskite solar cells.
