Abstract

In the past several years, organic-inorganic halide based perovskites has become an exciting topic in the field of photovoltaic community. Conventional perovskite solar cells (PSC) use 2,2′,7,7′-Tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene (spiro-OMeTAD) as a hole transporting layer (HTL), but the cost and stability of the polymeric HTL affects the scaling-up of PSC. This work, reports a hole- conductor free-ambient processed mixed halide PSCs with promising efficiency by tuning the morphology of the perovskite films by employing different deposition techniques (one step, two-step and dip coating method). In the dip coating method, unique cuboid structured films with good absorption and pin hole free films were obtained. The photovoltaic performances of the devices made by various deposition methods were measured at 1 sun illumination under standard conditions and achieved upto 6.5%.
