Herein, we studied the use of two different Self Assembled Monolayers (SAMs) made of semiconductor hole transport organic molecules to replace the most common p-type contact, PEDOT:PSS, in PiN methyl ammonium lead iodide perovskite solar cells (PSCs). The SAM molecule (MC-43) leads to a solar to energy conversion efficiency of 17.3, which is among the highest efficiencies reported to date for PiN perovskite solar cells. The present finding highlights the potential of semiconductor based SAMs to fabricate stable and high performing planar PSCs.

半导体自组装单层作为高效PiN钙钛矿太阳能电池的选择性触点†

在本文中，我们研究了使用两种不同的由半导体空穴传输有机分子制成的自组装单分子层（SAM）来代替PiN甲基铵碘化铅钙钛矿型太阳能电池（PSC）中最常见的p型触点PEDOT：PSS。SAM分子（MC-43）的太阳能转化为能量的效率为17.3，这是迄今为止报道的PiN钙钛矿型太阳能电池的最高效率。本发现突出了基于半导体的SAM制造稳定且高性能的平面PSC的潜力。
