Less toxic tin incorporated perovskite solar cell using polymer electrolyte processed in the air

Perovskite sensitizer materials based solar cell (PSSC) is freshly seemed as warm topic because very soon they achieve higher efficiency (∼20%) at incident light intensity 100 mw/cm² (1 sun condition). This paper deals the fabrication, characterization as well as application of perovskite material. Perovskite material i.e. MASnCl₃(CH₃NH₃SnCl3) was composed by coordinate statement of equimolar convergence of CH₃NH₃Cl and tin SnCl₂ in DMF arrangement. It was extra portrayed utilizing different characterization methods like X-Ray diffraction (XRD), UV–vis ingestion spectroscopy and Scanning electron microscope (SEM). PSSC has been fabricated utilizing methyl ammonium tri-tin chloride (CH₃NH₃SnCl₃) perovskite and polyethylene oxide (PEO) solid polymer electrolyte(SPE)sandwiched between perovskite working electrode (WE) and platinum counter electrode (CE) and its implementation at room condition has been accounted for in this paper. The fabricated PSSC demonstrates a short out current density (Jsc) of 1.8 mA/cm², Voc of 0.48 V, fill factor of 0.68 and efficiency (ɳ) of 0.60% at one sun condition.
