{{Main|Thin-film solar cell}}
Flexible, thin-film [[solar cell]]s have been developed for powering [[satellite]]s. These cells are lightweight, can be rolled up for launch, and are easily deployable, making them a good match for the application. They can also be sewn into backpacks or outerwear,<ref>See for instance the [[Scottevest]] solar jacket and the Voltaic [http://www.voltaicsystems.com/offgrid.shtml] {{Webarchive|url=https://web.archive.org/web/20140115021756/http://www.voltaicsystems.com/offgrid.shtml|date=2014-01-15}} and similar solar backpacks.</ref> among many other types of consumer-oriented applications. 

The growing markets related with flexible and/or portable electronics, such as for self-powered [[Internet of things|IoT systems]], have driven the development of bendable [[Thin-film solar cell|thin-film photovoltaics]] (PV) in view of enhancing the energetic autonomy of such off-grid devices.<ref>{{Cite journal |last1=Vicente |first1=António T. |last2=Araújo |first2=Andreia |last3=Mendes |first3=Manuel J. |last4=Nunes |first4=Daniela |last5=Oliveira |first5=Maria J. |last6=Sanchez-Sobrado |first6=Olalla |last7=Ferreira |first7=Marta P. |last8=Águas |first8=Hugo |last9=Fortunato |first9=Elvira |last10=Martins |first10=Rodrigo |date=2018-03-29 |title=Multifunctional cellulose-paper for light harvesting and smart sensing applications |url=https://pubs.rsc.org/en/content/articlelanding/2018/tc/c7tc05271e |journal=Journal of Materials Chemistry C |language=en |volume=6 |issue=13 |pages=3143–3181 |doi=10.1039/C7TC05271E |issn=2050-7534|url-access=subscription }}</ref> It has been shown that this class of PV technologies is already capable of reaching high solar-to-electricity efficiencies, at the level of rigid wafer-based solar cells, particularly when integrated with effective light-trapping structures. Such photonic schemes allow high broadband absorption in the thin PV absorber materials, despite their reduced thickness required for mechanical bendability.<ref>{{Cite journal |last=Haque |first=Sirazul |date=2022 |title=Photonic-Structured Perovskite Solar Cells: Detailed Optoelectronic Analysis |url=https://pubs.acs.org/doi/10.1021/acsphotonics.2c00446 |journal=ACS Photonics |volume=9 |issue=7 |pages=2408–2421 |doi=10.1021/acsphotonics.2c00446 |s2cid=250013073 |via=ACS|url-access=subscription |hdl=10773/35989 |hdl-access=free }}</ref><ref>{{Cite journal |last1=Boane |first1=Jenny L.
