Interface Engineering in Perovskite Solar Cells by Low Concentration of Phenylethyl Ammonium Iodide Solution in the Antisolvent Step

Abstract: MA0.5FA0.5PbI3, increasing the average photoconversion efficiency (PCE) respect the reference cell by 18, 32 and 4 % respectively, observed for regular, n-i-p, and inverted, p-i-n, solar cell configurations. This analysis highlights the generality of this approach for halide perovskite materials in order to reduce non-radiative recombination as observed by impedance spectroscopy.

“…To distinguish between these factors, we performed experiments on samples of two-dimensional Ruddlesden–Popper layered perovskites containing phenylethylammonium (PEA + ) spacers, , which allow the dynamic FA + cation to be removed and systematically reintroduced in the different homologues. These low-dimensional perovskites are characterized by the number of inorganic layers per organic layer ( n ), as shown in Figure a.…”

“…Ripolles et al., used ORIS to analyze the interface treatment in single‐cation and double‐cation PSCs. [ 90 ] A very low concentration of phenylethyl ammonium iodide (PEAI) salt (0.0002–0.012 m ) was added during the antisolvent step in device fabrication to passivate interfacial vacancies and improve moisture stability. IS measurements were performed at V OC under 1 Sun illumination for PSCs with and without PEAI.…”

“…38 In 2016, Han et al utilized PCBM for the rst time to create a graded heterojunction between a perovskite and PCBM, using a one-step antisolvent fabrication method to achieve a controlled fullerene distribution. 39 Subsequently, other approaches were presented, including mainly organic molecules [40][41][42] and perovskite quantum dots, [43][44][45] but also polymers. 46 In the present study, we employ OABr for the rst time in inverted PSCs, by inserting OABr in an antisolvent mixture.…”
