Perovskite solar modules set a certified efficiency mark by fixing laser-scribe damage

What happened

Researchers adjusted crystallization around the laser-scribed lines that electrically connect perovskite solar modules, where heat and structural defects can reduce performance during scale-up. They reported efficiencies of 24.70 percent for a 25-square-centimetre module and 23.89 percent for a 100-square-centimetre module, including a certified 23.55 percent result for the larger device.

Why it matters

The work addresses a specific scale-up loss rather than only improving a tiny research cell. It remains a laboratory module, however: the reported low-humidity storage test does not establish commercial-panel manufacturing yield, outdoor lifetime, damp-heat tolerance, lead containment, or cost.

What to watch

• Independent certification of full-size modules plus encapsulated outdoor, damp-heat, thermal-cycling, and mechanical-load testing.
• Factory yield, material and process costs, lead containment, recycling, and whether the laser-scribe treatment works on commercial production lines.

Sources & evidence

• Regulating perovskite crystallization kinetics at laser scribe lines for efficient and stable perovskite modulesPeer-reviewed Article in Nature Communications 17, published February 20, 2026. The team fabricated 25- and 100-square-centimetre laboratory modules and reported a certified 23.55 percent efficiency for the larger device. This is DEMONSTRATED / PILOT evidence, not commercial deployment; the unencapsulated stability result was 93 percent retention after 3,120 hours of storage at about 15 percent relative humidity rather than years of outdoor operation.
