The most efficient perovskite solar cell devices use Pb(II); however, the toxicity of lead and its decomposition products represent possible obstacles to their widespread commercial and carbon impact.(1,2) Pb from hybrid perovskites may enter plants—and consequently the food cycle—10× more efficiently than do other Pb sources.(3) Although consumer solar modules are encapsulated, there remain concerns

The intensifying energy crisis and detrimental environmental impacts have stimulated enormous interest in developing clean and renewable energy sources to decrease the dependence on traditional fossil energy.(1−4) Electrochemical water splitting is considered to be an important supplement of hydrogen energy, which contains two half reactions, namely, hydrogen evolution reaction (HER) at the cathode(5)

Ammonia is an industrial large-volume chemical. It is used in fertilizers and many chemical products and materials, and it pops up as a candidate green energy vector. Today, the industrial production of ammonia is dominated by the Haber–Bosch process departing from natural gas or other fossil fuel. This process is responsible for about 1.6% of the global CO2 emissions. Electrochemical ammonia production

Designing a scalable system to capture CO2 from the air and convert it into valuable chemicals, fuels, and materials could be transformational for mitigating climate change.(1−3) Climate models predict that negative greenhouse gas emissions will be required by the year 2050 in order to stay below a 2 °C change in global temperature.(4) The processes of CO2 capture, CO2 conversion, and finally product

Owing to highly conductive solid ionic conductors, all-solid-state batteries attract significant attention as promising next-generation energy storage devices. A lot of research is invested in the search for and optimization of solid electrolytes with higher ionic conductivity. However, a systematic study of interlaboratory reproducibility of measured ionic conductivities and activation energies is

Stationary electric energy storage is anticipated to play an increasingly important role in the efficient, reliable, and sustainable delivery of electricity, especially with increasing deployment of low cost intermittent renewable energy sources. Redox flow batteries (RFBs) are a promising electrochemical technology whose decoupling of power and energy scaling, long operational lifetimes, and safety
