“…To explore whether spray coating could be successfully used to coat PSCs onto nonplanar surfaces, devices were fabricated on flat substrates held at a series of different inclinations (15,30,45, and 60°) away from the horizontal (see Figure 1b). In these experiments, devices were fabricated onto commercially available prepatterned 8-pixel glass/ITO substrates.…”

“…14 Of these techniques, spray coating is unique in the fact that the solution delivery nozzle does not need to be positioned close to the surface on which the film is to be deposited. This, in principle, allows spraybased techniques to be used to rapidly coat nonplanar, nonhorizontal substrates 15 as is�for example�used to apply surface coatings in the automotive industry. Indeed, ultrasonic spray coating has previously been used to fabricate colloidal quantum dot solar cells on rigid hemispherical surfaces, indicating that this is not an unreasonable target.…”

Spray coating is an industrially mature technique used to deposit thin films that combines high throughput with the ability to coat nonplanar surfaces. Here, we explore the use of ultrasonic spray coating to fabricate perovskite solar cells (PSCs) over rigid, nonplanar surfaces without problems caused by solution dewetting and subsequent "run-off". Encouragingly, we find that PSCs can be spray-coated using our processes onto glass substrates held at angles of inclination up to 45°away from the horizontal, with such devices having comparable power conversion efficiencies (up to 18.3%) to those spray-cast onto horizontal substrates. Having established that our process can be used to create PSCs on surfaces that are not horizontal, we fabricate devices over a convex glass substrate, with devices having a maximum power conversion efficiency of 12.5%. To our best knowledge, this study represents the first demonstration of a rigid, curved perovskite solar cell. The integration of perovskite photovoltaics onto curved surfaces will likely find direct applications in the aerospace and automotive sectors.
