Slot-die coating fabrication of perovskite solar cells toward commercialization

Slot-die coating of electron transport layers for perovskite solar cells using water and butanol-based tin oxide dispersions

“…Therefore, it is important to develop suitable printing methods for each layer of the perovskite solar cell. 6,7 The perovskite solar cell device n-i-p stack consists of a glass substrate with a transparent conductive oxide (TCO), electron transport layer (ETL), perovskite layer, p-type hole transport layer (HTL) and metal back contact electrode. 8 Carrier-selective ETL and HTL are crucial for extracting and transporting charges, while minimizing the interfacial charge recombination.…”

Recent studies on small molecular and polymeric hole‐transporting materials for high‐performance perovskite solar cells

“…With regard to renewable energy resources, solar, wind, and biomass energy are all considered as viable alternatives to fossil fuels [2]. To this end, intense research is now being conducted on solar cell technologies with the aim of reducing the cost and increasing the power conversion efficiency (PCE) in order to improve large‐scale commercial production of this technology [3–25].…”

Fabrication of low-cost and flexible perovskite solar cells by slot-die coating for indoor applications

“…7 However, one-step slot-die coating is currently the most promising one, given its straightforward integration into a roll-to-roll (R2R) system (which enables a high-throughput production capability), and the high photovoltaic performances already attained using this technique. 8 In 2023, Jinzhao et al reported an astonishing 22.3% efficiency in a 0.2 cm 2 cell under 1 sun using a metal electrode and rigid substrate. Furthermore, encapsulated devices could withstand more than 1 year under continuous maximum power point tracking (MPPT) in outdoor real conditions, with virtually no decrease in efficiency.…”
