Harnessing Functionalized Thioalkylated-Cyclopentadithiophene Monolayers on NiOx for Two-Step Fabricated Tin Perovskite Solar Cells.

ABSTRACT: A new series of dithioalkylated-methylidenyl-cyclopentadithiophene (CDTS)-based self-assembled monolayers (SAMs), including CDTS-MN (1), CDTS^b-MN (1b), CDTS-CA (2), and CDTS-PA (3), are developed for tin perovskite solar cells (TPSCs). Each SAM incorporates sulphur rich center CDTS and is complemented with various anchoring groups, such as methylenemalononitrile, cyanoacrylic acid, and cyano-vinyl-phosphonic acid in driving the formation of well-crystallized and homogeneous perovskite layers using a two-step fabrication process. Nickel Oxide (NiOx) combined with the newly designed CDTS-based SAMs is utilized as the hole transport material (HTM). This configuration yielded an excellent power conversion efficiency (PCE) of 8.41% for CDTS-MN (1) TPSC device as compared to CDTS
