Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells
Advanced Functional Materials, EarlyView.ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Advanced Functional Materials, EarlyView.ABSTRACT Perovskite solar cells (PSCs) are promising next‐generation photovoltaics. The high performance of PSCs is attributed to the long carrier lifetimes of perovskite photoabsorbers. However, the carrier lifetimes of polycrystalline perovskite layers, which serve as the photoabsorbers in practical PSCs, have remained limited to several tens of ...

Advanced Functional Materials, EarlyView.Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

Nanostructures in photovoltaics
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2006 The world has recently been waking up to the urgent need to move away from fossil fuels and towards a low-carbon economy. To achieve this, we need a way of producing electricity that is efficient, widely applicable and cheap. At the same time, there has recently been an appreciation of the tremendous scope for making entirely new types of devices, and ...
