Despite historical failure, cylindrical solar tubes may still find a place in BIPV market, say Japanese scientists

Solyndra’s cylindrical CIGS solar technology highlighted both the promise and challenges of unconventional PV designs, but a new study from Japan suggests that cylindrical modules may still offer advantages in building-integrated applications. Researchers in Japan found that their curved geometry improves cooling, reduces temperature-related losses, and enables more stable energy harvesting under optimized urban installation conditions.
