Efficient Near-Infrared Harvesting in Perovskite–Organic Tandem Solar Cells

Scientists break out infrared tech to solve issue holding back next-gen solar panels: 'This makes the technology promising not just in the lab'

In a major leap for clean energy, scientists have figured out how to make solar panels that are lighter, more efficient, and — for the first time — durable enough for everyday use. A research team led by the Swiss Federal Institute of Technology in Lausanne, Switzerland, has developed a new method for making perovskite solar cells more stable in real-world conditions. The results, published in Joule, are exciting for solar fans everywhere. Perov…

Efficient near-infrared harvesting in perovskite–organic tandem solar cells

The broad bandgap tunability of both perovskites and organic semiconductors enables the development of perovskite–organic tandem solar cells with promising theoretical efficiency. However, the certified efficiencies of reported perovskite–organic tandem solar cells remain lower than those of single-junction perovskite solar cells, primarily because of insufficient near-infrared photocurrent in narrow-bandgap organic subcells1–3. Here we design a…

Charging indoor devices with light from lamps and LEDs

Los Angeles CA (SPX) Jun 26, 2025 Perovskite solar cells (PeSCs) may soon power household electronics not from sunlight, but from fluorescent bulbs and ambient indoor lighting. Researchers from National Yang Ming Chiao Tung University in Taiwan have developed PeSCs tailored specifically for indoor conditions, as detailed in APL Energy, published by AIP Publishing. Unlike rigid, heavy silicon-based solar panels commonly use

Breakthrough Solar Technology: NUS Scientists Achieve World-Record Efficiency in Perovskite-Organic Tandem Solar Cells

Scientists at the National University of Singapore (NUS) have demonstrated a perovskite–organic tandem solar cell with a certified world-record power conversion efficiency of 26.4 per cent over a 1 cm2 active area — making it the highest-performing device of its kind to date. This milestone is driven by a newly designed narrow-bandgap organic absorber that significantly enhances near-infrared (NIR) photon harvesting, a long-standing bottleneck i…

Scientists solve key weakness in perovskite solar cells

A team of researchers in China has made a major breakthrough that could lead to more efficient and longer-lasting solar panels. The team, led by Professor Ge Ziyi at the Ningbo Institute of Materials Technology and Engineering, has developed a new way to protect a key part of solar panels known as all-perovskite tandem solar […] The post Scientists solve key weakness in perovskite solar cells appeared first on Knowridge Science Report.
