Glittering solar-paneled roofs atop residential, commercial, and industrial buildings may soon get a new look with the carbon-based organic solar cell or OSC. Thinness and flexibility partly explain why OSCs may be a better alternative to traditional silicon-based cells. But not all OSCs are created equal. Those based on nonfullerene-acceptors, or NFAs, […]
Zinc-air batteries, which produce electricity through a chemical reaction between oxygen in the atmosphere and zinc, are considered to be next-generation candidates to meet the explosive demand for electric vehicles instead of lithium-ion batteries. They theoretically meet all required characteristics for next-generation secondary batteries, such as; high energy density, low risk of explosion, eco-friendliness […]
When popular Indian singer Chinmayi Sripaada shared photos of recently cleaned roof solar panels on his in -laws in Chennai on social media, he highlighted how his family tapped into clean power when energy demand rose amid more extreme heat. In response, several million of her Twitter followers wrote back, asking about the cost of […]
A new study by Chinese researchers demonstrates a novel approach to enhancing the storage performance of batteries and capacitors. The researchers developed a simple yet efficient way to produce a material with excellent performance for use in devices that rely on lithium-ion storage. Energy storage technologies are increasingly important as the world […]
Scientists have created a battery designed for the electric grid that locks in energy for months without losing much storage capacity. The development of the “freeze-thaw battery,” which freezes its energy for use later, is a step toward batteries that can be used for seasonal storage: saving energy in one season, such […]
For a greener and more sustainable economy, building better and more powerful solar cells is a key research goal within the clean energy sector. But, in a typical single-junction solar cell, performance is capped at what is called the Shockley-Queisser limit (a theoretical limit for the maximum efficiency that a solar cell can reach). […]
