Abstract
Flexible solar cells with competitive power-per-weight can be utilized in portable electric chargers, building-integrated photovoltaics, power sources for unmanned aerial vehicles, space-deployable solar arrays, and so on. Multiple-junction flexible solar cells present a promising pathway to surpass the theoretical Shockley-Queisser single-junction limit (33%). Perovskites are ideal photosensitive materials for multiple-junction flexible solar cells. Lead-based halide perovskites can be employed as ideal absorbers in middle- or wide-band-gap subcells, and flexible narrow-band-gap absorbers like lead-tin mixed perovskites, Cu(In, Ga)(S, Se)2, organic semiconductors, and Si are compelling candidates for bottom subcells in perovskite-based multiple-junction flexible solar cells. In this review, we summarize the progress made so far; provide an outlook on potential device configurations; discuss strategies to overcome related challenges; and offer a perspective on configuration design, material choice, encapsulation, and scalable fabrication of perovskite-based multiple-junction flexible solar cells.
