鈣鈦礦太陽(yáng)能電池的聚芳族分子接觸 ▲ 作者:Ke Zhao, Qingqing Liu et al. ▲鏈接: https://www.nature.com/articles/s41586-024-07712-6 ▲摘要: 在此,我們報(bào)告了一種沒有雜原子取代的環(huán)繞稠合多環(huán)芳烴核心結(jié)構(gòu),它比傳統(tǒng)的雜原子取代核心結(jié)構(gòu)具有更好的載流子傳輸和選擇性。 這種核心結(jié)構(gòu)產(chǎn)生了相對(duì)化學(xué)惰性和結(jié)構(gòu)剛性的分子接觸,可以大大提高鈣鈦礦太陽(yáng)能電池在效率和耐用性方面的性能。在不同的加速老化測(cè)試中,裝置的效率高達(dá)26.1%,大大提高了使用壽命。 ▲ Abstract: Here we report a peri-fused polyaromatic core structure without heteroatom substitution that yields superior carrier transport and selectivity over conventional heteroatom-substituted core structures. This core structure produced a relatively chemically inert and structurally rigid molecular contact, which considerably improved the performance of perovskite solar cells in terms of both efficiency and durability. The champion device showed an efficiency up to 26.1% with greatly improved longevity under different accelerated-ageing tests. |
