In a major breakthrough for clean energy, scientists have developed a new type of solar panel that can generate electricity using indoor artificial light —a solution that could revolutionize how we power everyday electronic devices. This innovative technology is based on perovskite solar cells , a next-generation material increasingly used to improve the efficiency of solar energy systems. Unlike traditional silicon-based solar panels , which primarily rely on direct sunlight, perovskite materials can harness energy from indoor sources such as LED and fluorescent bulbs. Learn more about how perovskite solar cells work . Despite their potential, early versions of perovskite solar cells had limitations—they were unstable and less efficient due to minor chemical flaws. However, a team of researchers at National Yang Ming Chiao Tung University in Taiwan has solved this issue using a chemical technique called "band gap adjustment" . This method enhances the material’s efficienc...

In today’s always-connected world, keeping your phone battery fully charged feels like a necessity. However, battery experts warn that charging your mobile phone to 100% every day may actually reduce its overall lifespan. According to Zhou Yang Wang , Director of the Electrochemical Engine Center at Penn State University , fully charging your battery to 100% on a daily basis causes accelerated wear and tear on the battery. “Charging the battery to full capacity puts it under stress, especially when done regularly,” he explained. Wang estimates that consistently charging a phone to 100% instead of 90% can reduce the battery’s lifespan by 10 to 15% .
