Agrivoltaics can help lettuce survive extreme heat
Scientists have grown organic romaine lettuce under 13 different types of PV modules, in an unusual hot Canadian summer. Their analysis showed lettuce yields increased by over 400% compared to unshaded control plants.
Chinese PV Industry Brief: Polysilicon output set to fall by 15% in January
Polysilicon trading in China remained largely inactive, with production cuts accelerating and wafer prices falling week on week, while downstream cell prices continued to rise and module prices held steady, according to a trade group representing China’s nonferrous metals sector.
Study finds much lower-than-expected degradation in 1980s and 1990s solar modules
Researchers at SUPSI found that six Swiss PV systems installed in the late 1980s and early 1990s show exceptionally low degradation rates of just 0.16% to 0.24% per year after more than 30 years of operation. The study shows that thermal stress, ventilation, and material design play a greater role in long-term module reliability than altitude or irradiance alone.

Korean scientists boost performance of tin monosulfide cells with new post-treatment
Researchers in South Korea improved the performance of tin monosulfide (SnS) solar cells with a potassium fluoride-assisted post-treatment and a vapor transport deposition process. The treated solar cells had a power conversion efficiency of 4.10% and reduced recombination sites, compared to 3.42% for untreated devices.
A closer look at Tesla’s new residential solar panels
The new Tesla Solar Panel and mounting system pairs with the company’s inverter, Powerwall battery, EV charging and vehicles, creating an all-Tesla residential solar offering for the first time.
