The Performance of CH3NH3PbI3 - Nanoparticles based – Perovskite Solar Cells Fabricated by Facile Powder press Technique
  Here, we have introduced a facile solid-state route assisted method to prepare CH3NH3PbI3 perovskite nanoparticles (PNs) and together with a facile - powder press technique, for the deposition of prepared PNs - a solution cum vacuum-free route. The perovskite layer was prepared using different lead iodide (PbI2) precursor molar concentrations (0.5, 1, 1.5, 2 mmol) and the PbI2 concentration was found to have a significant impact on the structural, optical, morphological and electrical properties. The sample prepared using molar ratio PbI2: MAI at 1:3 shows the optimal bandgap value (∼1.51 eV), broader band edge peak at 755 nm and found have good optical property for photovoltaic (PV) applications. The J–V performance of the fabricated perovskite device with FTO/c-TiO2/mp-TiO2/Perovskite/CuI/ Cr/Pt-coated FTO counter electrode has been studied. The device fabricated using the concentration at PbI2:MAI 1:3 achieved a PCE of 3.9% and resulted in better long-term stability with deterioration in η and VOC by 27.87% and 29.23% after 15 days.
