Consequently, this has led to improved coverage of the perovskite layer and enhanced overall photovoltaic performance of the solar cells. Experimental results indicate that the m-TiO 2 film subjected to 60 min of concentrated sunlight sintering (CSS) demonstrates optimal photovoltaic performance, with the fabricated compact-layer-free PSCs achieving an
The results demonstrate an improvement (1.28%-2.83%) in the photovoltaic conversion efficiency of the optimized mixed glass sample compared to pre-mixing and using a single glass frit. This improvement is attributed to altering the characteristic temperature, wettability, and etching properties of the glass during melting, thereby
