概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
To enhance the interaction with the host perovskite matrix and solar cell performance, we modify the surface and shape of both the perovskites and silicon quantum dots. Our approach involves utilizing femtosecond laser (fs laser) at wavelengths of 800 and 400 nm, varying the intensity as a key parameter.
実験 / Experimental
One representative experiment outcome is depicted in FIG. 1a below, obtained by focusing the fs laser beam at a wavelength of 400 nm on the solution containing SiQDs. The quantum dots (QDs) are dispersed in various solutions such as water, octane, and hexene.
結果と考察 / Results and Discussion
The laser-treated SiQDs are subsequently introduced to perovskites to fabricate solar cells. Figure 1b illustrates typical J-V curves of solar cells based on perovskite, with and without laser-treated SiQDs. It's evident that there's an enhancement in the IV characteristics upon the introduction of laser-treated SiQDs.
