Clean energy is the leading solution for climate change. But solar and wind power are inconsistent at producing enough energy for a reliable power grid. Alternatively, lithium-ion batteries can store energy but are a limited resource.
Perovskite solar cells (PSCs) are extremely efficient, can outperform conventional silicon solar cells, and have the ability to transform renewable energy. One of the existing constraints prohibiting its widespread acceptance is a lack of operational dependability.
The capability of batteries to power microdevices, microrobots, and implanted medical devices has been constrained by the long-standing technological challenge of translating the electrochemical performance of large format batteries to microscale power sources.
New breakthroughs have been made by a research group headed by Tao Sun associate professor of materials science and engineering at the University of Virginia.
In daily human life, batteries tend to play a major role everywhere, right from cell phones and smart watches to the growing number of electric vehicles.
While people may be only beginning to benefit from the advantages of 5G wireless technology, scientists all over the world are already focusing their efforts on the next generation: 6G.
Carbon dioxide (CO2) is a greenhouse gas produced when fossil fuels are used to produce energy. Using sunlight, researchers are striving to convert CO2 into valuable compounds or fuels.
The chemical engineers from EPFL (École polytechnique fédérale de Lausanne) have devised a solar-powered artificial leaf, that has been constructed on the basis of a novel electrode that seems to be porous and transparent, thereby exhibiting the potential of harvesting water from the air for transforming into hydrogen fuel.
Recent research published on December 21st, 2022, in the Energy Material Advances journal outlines the degradation mechanisms and examines the interfacial engineering focusing on their impacts on flexible perovskite solar cells.
When exposed to sunlight, perovskite solar cells degrade, resulting in decreased performance over time.
