New Solar Panel Technology Generates Power from Indoor Artificial Light

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.

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 efficiency under artificial lighting conditions, a feat not possible with conventional silicon panels. The breakthrough allows perovskite solar cells to be used reliably for daily indoor applications.

According to the research team, this advancement could lead to practical energy solutions for wearable devices, remote controls, and IoT gadgets, all of which require small but continuous power supplies.

As the demand for sustainable energy sources rises, this development marks a promising step toward green technology adoption in everyday life.
