    Organic photovoltaics are promising for indoor applications, yet their voltage losses are large and limit device performance. Here, Cui et al. present a wide-gap non-fullerene acceptor that retains a voltage of 1.1 V at low light intensities enabling an efficiency of 26.1%.

    CdTe solar cells have relied for decades on copper, which creates limited hole density, stability issues and a ceiling for voltage and efficiency. Now, Metzger et al. demonstrate As-doped Cu-free polycrystalline CdTe cells with enhanced hole density and dopant stability, achieving 20.8% efficiency.

    Although solar photovoltaic use grows rapidly in China, comparison with grid prices is difficult as photovoltaic electricity prices depend on local factors. Using prefecture-level data, Yan et al. find that 100% of user-side systems can achieve grid parity, while 22% can produce electricity cheaper than coal-based power plants.

    Ultrathin solar cells having thicknesses below 1 µm can still reach efficiencies comparable to their thicker counterparts, but require less material to manufacture. By exploiting light-trapping nanostructures, Chen and colleagues achieve GaAs solar cells with 20% efficiency at just 205 nm thicknesses.

    Many different molecules can form during photocatalytic reduction of CO2, so identifying catalyst structure–product selectivity relationships is vital. Here, the authors find that sulfur-deficient CuIn5S8 is highly selective to CH4 and suggest that the presence of Cu–In binding sites is key to this behaviour.

    China is the biggest manufacturer of solar photovoltaics, and with declining local costs coupled with potential pollution reduction and health co-benefits, domestic use of solar photovoltaics might surge even more dramatically in the very near future.

    A conventional lithium-ion battery makes use of both an anode and a cathode. Now, a new design of batteries with no anodes in their initial state is shown to be promising for practical applications.
