摘要

本文评估了未取代的聚对二甲苯（苝- n）薄膜作为MAPbI3钙钛矿太阳能电池（PSCs）的封装材料。与更常用的聚苯乙烯- c不同，聚苯乙烯- n更便宜，不含氯，这使它成为钙钛矿材料的有前途的封装剂。通过在真空中室温化学气相沉积，2mm厚的聚对二甲苯薄膜稳定了基于mapbi3的太阳能电池，即使在应力测试条件下（空气中85°C）也能抑制降解。此外，用聚苯乙烯- n薄膜和覆盖玻璃封装的太阳能电池在黑暗环境中表现出超过3800小时的稳定特性，保持了92%的初始功率转换效率。这些结果证明了未取代的聚对二甲苯在PSC稳定方面的潜力，为新型和高度稳定的PSC铺平了道路。

Improved Operational Lifetime of MAPbI3 Solar Cells Encapsulated with Parylene-N

Herein, unsubstituted poly-para-xylylene (parylene-N) film as an encapsulation material for MAPbI₃ perovskite solar cells (PSCs) is assessed. Unlike more commonly used parylene-C, parylene-N is cheaper and does not contain Cl which makes it a promising encapsulant for perovskite materials. Being deposited by room temperature chemical vapor deposition in a vacuum, 2 mm-thick parylene film stabilizes MAPbI₃-based solar cells and inhibits the degradation even under stress test conditions (85 °C in the air). Moreover, the solar cells, encapsulated with the parylene-N film and cover glass, show stable characteristics for over 3800 h in a dark ambient atmosphere, retaining 92% of their initial power conversion efficiency. Such results demonstrate the potential of unsubstituted parylene for PSC stabilization, paving the way for novel and highly stable PSCs.

期刊介绍： Solar RRL, formerly known as Rapid Research Letters, has evolved to embrace a broader and more encompassing format. We publish Research Articles and Reviews covering all facets of solar energy conversion. This includes, but is not limited to, photovoltaics and solar cells (both established and emerging systems), as well as the development, characterization, and optimization of materials and devices. Additionally, we cover topics such as photovoltaic modules and systems, their installation and deployment, photocatalysis, solar fuels, photothermal and photoelectrochemical solar energy conversion, energy distribution, grid issues, and other relevant aspects. Join us in exploring the latest advancements in solar energy conversion research.
