In this paper,[1] we report two novel D-pi-D hole-transporting materials(HTM),abbreviated as BDT-PTZ and BDT-POZ,which consists of 4,8-di(hexylthio)-benzo[1,2-b:4,5-b]dithiophene(BDT)as conjugated lin
Additive engineering is one of the commonly used method to improve the performance of PMPSCs.So,we have used melamine hydroiodide(MLAI)as an additive for preparing PMPSCs[1].
近年来,基于有机无机杂化钙钛矿材料的太阳能电池由于成本低廉、制备工艺简单等特点,一直以来都是全球范围内研究人员的关注热点,其光电转换效率目前已经逼近了单结硅基太阳能电池的转换效率。

具有良好表面形貌和较大尺寸晶粒的有机-无机杂化金属卤化物钙钛矿薄膜是实现高性能光伏器件的理想材料。然而,混合前驱体溶液结晶过程中卤化铅与阳离子之间的快速反应导致了小尺寸晶粒的产生;同时,缺陷位点也不可避免地存在于在晶界和钙钛矿薄膜表面。
Herein,a novel molecule: p-phenyl dimethylammonium iodide(PDMAI)with ammonium group on both terminals is introduced.
一步反溶剂法已经被认为是制备高效钙钛矿太阳能电池的最可行的方法之一[1]。然而,大多被报道的高效钙钛矿太阳能电池是基于有毒反溶剂制备的,这严重影响了钙钛矿太阳能电池的商业化[2]。
有机无机杂化钙钛矿材料在光伏领域受到了广泛关注,然而铅基钙钛矿的毒性为其应用带来了一定的限制,开发无毒或低毒的非铅钙钛矿太阳能电池具有重要意义。其中,锡基钙钛矿材料具有理想的带隙和高的载流子迁移率,是一种低毒的光伏材料。
