报告摘要：

Comparedto the traditional-architecture perovskite photovoltaics (n-i-p type), whichuse metal oxide as electron transport layers(ETLs) and organic semiconductingmaterials as hole transport layers, the fabrication of metal-oxide-free,solution-processed inverted perovskite solar cells (PSCs, Figure 1) is moredesired because of low-temperatures and all-solution-based applications in futurecommercial PSC modules. In a typical configuration of inverted PSCs, the widelyused ETL compound is the fullerene-based phenyl-C61-butyric acid methyl ester(PCBM), which currently is the best organic ETL material. The cost of thiscompound is very high, and the morphology and electrical properties are verysensitive to experimental conditions. In this talk, I will talk the recentprogress of new organic ETL materials in my group for the replacement of PCBMin inverted PSCs. We believe that easily-accessible simple n-type smallmolecules are promising ETL candidates to further propel inverted PSCs topractical applications.
