Abstract The utilization of wide bandgap (WBG) tin halide perovskites (Sn‐HPs) offers an environmentally friendly alternative for multi‐junction Sn‐HP photovoltaics. Nonetheless, rapid crystallization leads to suboptimal film morphology and substantial creation defect states, which undermine device efficiency. This study introduces 4‐Phenylthiosemicarbazide (4PTSC) as additive achieve a densely packed with fewer imperfections. strong chemical coordination between SnI 2 the functional groups...
Tin-based halide perovskites (Sn-HPs) are emerging as promising alternatives to lead-based in solar cells due their reduced toxicity and advantageous optoelectronic properties. However, Sn-HPs face significant challenges such...
Abstract An ordered self‐assembly of CsPbBr 3 quantum dots (QDs) was generated on the surface few‐layer black phosphorus (FLBP). Strong quenching QD fluorescence observed, and analyzed by time‐resolved photoluminescence (TR‐PL) studies, DFT calculations, photoconductivity measurements. Charge transfer type I band alignment is suggested to be cause observed effects.
In the present work, we have endeavored utilization of wet-chemically synthesized copper oxide nanoparticles (CuO-NPs) as active layer in hybrid bulk heterojunction (BHJ) solar cells. The BHJs with CuO-NPs display significantly different physics from customary BHJs, and prove a noteworthy improvement their performance. It is noted that addition CuO-NPs, morphology photoactive endures significant changes. Incorporating an additional paradigm for cells which enhances photocurrent density 9.43...
A van der Waals heterostructure between all-inorganic CsPbBr3 halide perovskite quantum dots (CPB QDs) and Ti3C2Tx MXene (MXN) QDs is realized, the photophysics of composite examined. strong quenching steady-state photoluminescence observed, which further examined by a time-resolved study.
