An organometal halide perovskite light absorber is a promising material for solar cell applications. On the other hand, the poor stability of perovskite under normal conditions has limited its wider industrial applications. This paper reports that the solar cell architecture can be simplified by removing the hole transporting material HTM. In addition, device sealing helps reduce the degradation of perovskite over a relatively long period of time under ambient environmental conditions. Therefore, the simplified configuration of solar cells with TiO2 nanofibers/nanoparticles scaffold showed a power conversion efficiency of 6.68% and retained approximately 83% of their initial efficiency in 60 days in an ambient environment at room temperature.
