Overview
- The study, which was published on October 2, 2026, reported that broccoli grown under semi‑transparent magenta CdTe thin‑film panels reached similar final yields but needed about 25 extra days to mature.
- Plants beneath the magenta panels used sunlight far more efficiently, with a reported 4.5‑fold increase in light‑use efficiency under the denser panel configuration.
- The panels are glass modules with embedded opaque cadmium‑telluride strips that transmit red and blue light to crops while converting other wavelengths to electricity.
- In the trial the magenta system produced roughly 224.7 MWh per hectare over the growing period, about 100 MWh/ha less than comparable conventional panels, creating an economic trade‑off that analysts say would require about 1.2–3.2 tonnes of extra broccoli per hectare to offset the lost electricity.
- Authors warn the results come from 20 m × 20 m plots in a single 2024 season and say follow‑up work, including lab tests of red and blue filters and multi‑season, multi‑crop trials, is needed before wider farm use; they suggest early uses could include community gardens or greenhouse roofs and that on‑farm electricity could power irrigation or storage if systems scale.
