PG - 11424 LID - 10.1038/srep11424 [doi] LID - 11424 AB - Development of ternary metal oxide (TMO) based electron transporting layer (ETL) for perovskite solar cell open a new approaches toward efficient a unique strategy for solid state dye-sensitized solar cells (ssDSSCs). In the present investigation, highly porous zinc tin oxide (Zn2SnO4) scaffold nanofibers has been synthesized by electrospinning technique and successfully used for methyl ammonium lead halide (CH3NH3PbI3) perovskite sensitized solid state solar cells. The fabricated optimized perovskite solar cell devices exhibited 7.38% power conversion efficiency (PCE) with open circuit voltage (VOC) 0.986 V, current density (JSC) = 12.68 mAcm(-2) and fill factor (FF) 0.59 under AM 1.5 G sunlight (100 mWcm(-2)) which is higher than Zn2SnO4 nanoparticle (eta = 2.52%) based perovskite solar cells. This improvement is achieved due to high porosity of Zn2SnO4 nanofibers and high crystallinity of the nanofibers synthesized at 700 degrees C. These results are remarkably higher than reported perovskite solar cells based on such type of ternary metal oxide ETLs.
