Enhancing the performance and stability of MAPbI3 perovskite solar cells by inserting the ITO layer before the Ag electrode

چکیده
Diffusion of silver(Ag) from the electrode in perovskite solar cell layers presence moisture is a serious issue fabrication stable halide perovskite-based cells (PSC). We witnessed fast degradation fabricated planar p-i-n PSC having device structure as glass/ITO/PEDOT:PSS/MAPbI3/PCBM/Ag. This due to ambient and reaction Ag with form silver iodide(AgI). The diffusion into was easily noticeable after few hours fabrication. Therefore, suppress absorber layer, thin layer ITO indium tin oxide(ITO) incorporated PSC, between electron transport layer(ETL) which modified configuration glass/ITO/PEDOT:PSS/ MAPbI3/PCBM/ITO/Ag. It observed that performance stability this improved significantly compared without ITO. Using intermediate power conversion efficiency (PCE, η) 1% 8%, open-circuit voltage(Voc) = 0.86V, short-circuit current density(Jsc) 19.11mAcm-2, fill factor(FF)=0.49.

This investigation reports on the characteristics of MAPbI3 perovskite films on obliquely sputtered ITO/glass substrates that are fabricated with various sputtering times and sputtering angles. The grain size of a MAPbI3 perovskite film increases with the oblique sputtering angle of ITO thin films from 0° to 80°, indicating that the surface properties of the ITO affect the wettability of the PE...
