Abstract: Early studies suggest that absorption coefficient of GaN exceeds 100 cm ⁻¹ at wavelengths below 380 nm, indicating GaN might not be suitable as a waveguide (WG) material for laser diodes ...
Results from PV testing laboratories in 2024 have raised concern over ultraviolet-induced degradation (UVID) in some n-type TOPCon and HJT panels. The “PV Module Index Report” from the Renewable ...
