Organic–inorganic halide perovskite has excellent properties to function as light harvesters in solar cells
due to the possibility to tune its optical properties and to use it as thin film absorber, at a few hundrednanometer
thicknesses. Herein, we demonstrate the fabrication of perovskite solar cells with controlled
transparency, by the mesh assisted deposition process. Sequential fabrication of perovskite was
performed in air, wherein a PbI2 grid was formed in the first step, and in the second step, the grid
reacted selectively with methylammoniumiodide, resulting in a perovskite grid pattern. The best cells
were obtained with a photoanode composed of mesoporous TiO2 with Al2O3 nanoparticles. The
resulting semi-transparent perovskite solar cells, including a semi-transparent contact composed of
MoO3/Au/MoO3 yielded a power conversion efficiency of 5.5% with an average transparency of 26% and
efficiency of 8% for cells fabricated with a gold contact.
