Abstract
The insertion of tidy organic cations in metal halide perovskites with reduced‐dimensional (RD) crystal buildings increases crystal formation vitality and regulates the expansion orientation of the inorganic domains. Alternatively, the energy conversion performance is curtailed by the insulating nature of the tubby cations. Now a sequence of RD perovskites with 2‐thiophenmethylammonium (TMA) because the intercalating cation are investigated. Compared with current ligands, TMA demonstrates improved electron transfer within the inorganic framework. TMA modifies the shut to‐band‐edge integrity of the RD perovskite, making improvements to gap transport. A energy conversion effectivity of 19 % is carried out, the absolute best up to now for TMA‐primarily based entirely RD perovskite photovoltaics; these TMA units present a 12 % relative extend in PCE when put next with manipulate RD perovskite units that expend PEA because the intercalating ligand, a results of the improved charge transfer from the inorganic layer to the organic ligands.
