The use of organic hole transport material (HTM) is usually quite expensive owing to its synthesis procedure and high purity requirement. Therefore, we have synthesized an inexpensive, inorganic HTM, nickel oxide NiO in the laboratory. The perovskite precursor i.e., CH3NH3I was also synthesized in the laboratory and characterized for surface morphology and elemental analysis. Perovskite Solar Cell (PSC) was successfully prepared using NiO as the HTM with a supporting layer of polymer electrolyte. The fabricated sandwich structured PSC exhibited an open circuit voltage (Voc) of 0.77 V, short circuit density (Jsc) of 18 mA/cm2, and an effective photon conversion efficiency (PCE) of 5.13%.
