Self-assembly in Fabrication of Semitransparent and Meso–Planar Hybrid Perovskite Photovoltaic Devices

This chapter details our extensive work on fabrication of perovskite-based semitransparent solar cells through mesh-assisted self-assembly technique. The one-step deposition of perovskite layer has been realized and optimized toward achieving better transparency coupled with significant efficiency for these cells. Realization of novel meso–planar perovskite solar cells (PSCs), with both the mesoporous and planar cells on the same device using a self-assembly technique is also under the scope of the chapter. Good alignment and easy controllability for achieving the grids of different components of the cell through solution processes are major advantages of this technique, which is directed toward achieving the goal of fully printable PSCs.
