研究目的
Investigating the effects of spacer parameters on the properties and performance of fully printable mesoscopic perovskite solar cells.
研究成果
The study concludes that the size of spacer building blocks and the thickness of the spacer layer significantly affect the optoelectronic properties of perovskite, insulating property, and performance of fully printable mesoscopic perovskite solar cells. Advanced spacer film features, such as pore size larger than 100 nm and high porosity with ideal insulating ability, are proposed for future improvements.
研究不足
The study is limited by the inherent moisture and UV sensitivity of perovskite materials, which affects illumination stability. Additionally, the use of expensive and rare metals as back contacts may limit large-scale production.
