Coatings, Journal Year: 2022, Volume and Issue: 13(1), P. 4 - 4

Published: Dec. 20, 2022

The electron transfer layer (ETL) plays a vital role in achieving high-performance perovskite solar cells (PSCs). Titanium dioxide (TiO2) is primarily utilised as the ETL since it low-cost, chemically stable, and has simplest thin-film preparation methods. However, TiO2 not an ideal because leads to low conductivity, conduction band mismatch, unfavourable mobility. In addition, exposure of ultraviolet light induces formation oxygen vacancies at surface. To overcome these issues, doping with various metal ions favourable improve surface structure properties electronic properties. This review focuses on bulk modification via concentrations electrical optical properties, charge carrier density, interfacial electron–hole recombination, thus contributing enhancing power conversion efficiency (PCE) PSCs.

The optimization of nonradiative recombination losses through interface engineering is key to the development efficient, stable, and hysteresis-free perovskite solar cells (PSCs). In this study, for first time in cell technology, we present a novel approach modification by employing one-dimensional lepidocrocite (henceforth referred as 1DL) TiO2-based nanofilaments, NFs, between mesoporous TiO2 (mp TiO2) halide film PSCs improve both efficiency stability devices. 1DLs can be easily produced on kilogram scale starting with cheap earth-abundant precursor powders, such TiC, TiN, TiB2, etc., common organic base like tetramethylammonium hydroxide. Notably, 1DL deposition influenced grain development, resulting larger size more compact layer. Additionally, it minimized trap centers material reduced charge processes, confirmed photoluminescence analysis. overall promotion led an improved power conversion (PCE) from 13 ± 3.2 16 1.8% after modification. champion PCE 1DL-containing devices 17.82%, which higher than that 16.17% control passivation effect further demonstrated evaluating under ambient conditions, wherein maintain ∼87% their initial 120 days.

Abstract Perovskite-based solar cells have drawn a lot of attention recently because they possess many desirable qualities, including strong photon absorption, large carrier lifetime, ambipolar transmission, and low exciton binding energy. With continual optimization each functional layer, particularly the active layer hole transporting power conversion efficiency (PCE) perovskite materials has reached over 25%. Spiro-OMeTAD is widely utilized transport material (HTM) for efficient cell operation. To improve conductivity, this often doped with additives such as 4-tert-butylpyridine (TBP) or bis(trifluoromethane)sulfonimide lithium salt (Li-TFSI). Unfortunately, these can weaken reduce device stability.

When integrated into metal halide perovskite cells, FTO patterned low fluence conditions lead notable increase power conversion efficiencies (PCEs) compared those made untreated FTO. Importantly, preliminary stability tests devices based substrates show significantly improved fabricated reference unpatterned substrates. findings demonstrate that DLIP treatment technique can substantially efficiency photovoltaic devices.
