Three-dimensional/two-dimensional (3D/2D) heterojunctions in perovskite solar cells exhibit excellent optoelectronic properties and enhanced stability under mild ageing conditions. However, their performance degrades drastically harsh This study reveals...
Formamidinium (FA)-based perovskites exhibit significant potential for highly efficient photovoltaics due to their promising optoelectronic properties and optimal bandgap. However, the undesired inactive phase arises from multiple crystal nucleation pathways formed by various intermediate phases during film formation process, persistently accompanying it. FA-based frequently struggle form uniform, crystalline films. This challenge complicates development of reliable reproducible...
Abstract The ability of a series bridged triarylamines, so‐called N ‐heterotriangulenes, to form multilayer‐type 2D‐extended films via solution‐based processing method was examined using complementary microscopic techniques. We found that the long‐range order, crystallinity, and layer thickness decisively depend on nature substituents attached polycyclic backbone. Owing their flat core unit, compounds exhibiting carbonyl unit at bridge position provide superior building block as compared...
Two-dimensionally (2D) extended thin films of p-type organic semiconductor C13-BTBT (BTBT = [1]benzothieno[3,2-b]-[1]benzothiophene) were fabricated via self-controlled growth at the liquid–liquid interface. Depicting a compound class originally developed for further functionalization and subsequent realization self-assembled monolayers (SAMs), potent BTBT core unit commonly excels in high-quality structure formation as well charge-transport characteristics. Utilizing manifold...
