Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Low‐Temperature Gold Deposition Improves CdTe Back Contacts

Advanced Materials Interfaces, EarlyView.
Cd(Se,Te) samples are cooled during the evaporation of Au back contacts to thermally quench CdTe degradation. Reduced temperature during Au evaporation boosts PV efficiency, open‐circuit voltage, and fill factor. XPS associates these improvements with less chemical perturbation of the CdTe surface during metallization.
