Does moisture-assisted spraying improve the reproducibility of spray-prepared perovskite solar cells (PSCs)?

The moisture-assisted spraying strategy improves the reproducibility of spray-prepared perovskite solar cells (PSCs). The PSCs with an active area of 0.15 cm 2 achieve a PCE of 19.74%, while enlarged devices (64.8 cm 2) yield a PCE of 16.75%.

Can spray coating be used to manufacture perovskite solar cells?

Over the past six years, researchers have investigated the use of spray coating to fabricate perovskite solar cells (PSCs), with the aim of demonstrating its viability as an industrial manufacturing process.

When was spray coating first used in solar cells?

(39) Spray coating was used as early as 2004 to fabricate hybrid organic–inorganic perovskite-like materials; (40) however, the first use of spray-coated perovskites in solar cells was reported by our group (Barrows et al.) in 2014.

Can hydrogel coating be used on solar panels?

For instance, the coating can be directly sprayed onto solar back panels without requiring any additional disassembly/assembly process (Figure 5 A). During water spray cooling, the porous hydrogel coating can immediately capture the small water droplets to minimize water waste yet at the same time realize longer-lasting cooling.

Is spray coating effective for scalable wet processing of perovskite/silicon tandem solar cells?

The method was deemed as effective for scalable wet processing of perovskites on rough substrates particularly for production of perovskite/silicon tandem solar cell; although there is no evidence for outstanding PSCs performance . The spray coating process is classified based on the droplet generation process.

Who are the authors of gas assisted spray coating of perovskite solar cells?
