Product introduction

在钙钛矿太阳能电池中用途 Br-4PACz在钙钛矿太阳能电池中用作具有特定溴原子取代基的SAM形成剂。通过引入溴原子，它能够赋予SAM薄膜更特殊的界面化学性质和空穴传输特性，从而优化太阳能电池的性能。特别适用于反式钙钛矿太阳能电池，以及其他需要高效空穴传输和界面稳定性的太阳能电池器件。性能优点 1、溴原子效应: 溴原子的引入使得Br-4PACz具有独特的界面化学性质，能够更有效地钝化界面缺陷并促进空穴传输。 2、定制化性能: Br-4PACz的溴原子取代基可以根据具体应用场景和工艺需求进行调整，以满足定制化性能要求。 3、提高稳定性: 溴原子的存在还能够提高SAM薄膜的稳定性，延长太阳能电池的使用寿命。使用方法通常溶解在乙醇或异丙醇中，形成一定浓度的SAM形成剂溶液。可通过浸渍涂布或旋涂等方法应用于氧化物基底上，形成均匀的SAM薄膜。
