Abstract: Lead halide perovskite quantum dots, also known as perovskite nanocrystals, are considered one of the most promising photovoltaic materials for solar cells due to their outstanding optoelectronic properties and simple preparation techniques. The key factors restricting the photoelectric conversion efficiency of solar cell systems are the separation and transmission performances of charge carriers. Here, femtosecond time-resolved ultrafast spectroscopy was used to measure the interfacial charge t[...]

Our summary: Lead halide perovskite quantum dots show promising photovoltaic properties due to their optoelectronic features. The study analyzes the impact of CsPbBr3 size on charge transfer dynamics with TiO2 using ultrafast spectroscopy. Results indicate slower electron transfer and recombination as CsPbBr3 nanocrystals increase in size, suggesting potential for improved solar cell materials.
