    Organic solar cells can be thin, bendable and strechable. Now, Jinno et al. develop flexible organic photovoltaic devices that can also be washed in water and detergent, opening future integration routes into everyday objects such as fabric.

    Hydropower represents the largest source of renewable energy currently available, yet its potential provision remains poorly characterized. Gernaat et al. present a high-resolution global assessment of technical and economic hydropower potential based on an analysis of over 3.8 million individual locations.

    Radiative sky cooling passively rejects heat from a surface out into space via an atmospheric transparency window, enabling sub-ambient cooling. Goldstein et al. exploit this to show daytime cooling of water by up to 5 C below ambient temperature, equivalent to a heat rejection flux of 70 Wm−2.

    Despite being currently under-represented in IPCC reports, PV generation represents a growing share of power generation. This Perspective argues that underestimating PV potential led to suboptimal integration measures and that specific deployment strategies for emerging economies should be developed.

    To improve the efficiency of photovoltaic devices while keeping the same spatial footprint, solar cells can be stacked on top of each other. Here, Essig et al. fabricate very efficient dual-junction and triple-junction solar cells by placing one or two III–V solar cells on top of a silicon solar cell.
