    The performance of kesterite solar cells is limited by the formation of secondary phases and defects during the growth of their photovoltaic absorbers. New research shows that a tailored partial pressure of selenium leads to less-defective kesterite without the formation of intermediate phases, enabling 13.8%-efficiency solar cells.

    Hydrogen generated by sunlight could play a major role in a low-carbon future, but high-efficiency demonstrations have been limited mostly to very small scales. New research now evaluates a complete system that generates 0.5 kg of hydrogen per day with 20% device (5.5% system) efficiency while showing the benefits of coupled light absorption and water electrolysis.

    Photocatalytic hydrogen peroxide synthesis is a green approach to produce this widely-used chemical and potential energy carrier, yet performance is often poor. A porphyrin-based photocatalyst is now shown to produce hydrogen peroxide by an unusual mechanism involving both photoexcited electrons and holes with promising efficiency.

    Capping a three-dimensional metal halide perovskite with a layered, two-dimensional perovskite prevents ions from diffusing out of the perovskite keeping out oxygen and water as well as contributing to solar cell stability. New research shows that a thin cross-linked polymer layer can ensure that the boundary between the 3D and 2D materials remains sharp, further improving stability.
