This review focuses on applications of ALD in DSPECs for the preparation of solar fuels based on modified semiconductor surfaces. In this area, ALD has been used to prepare core/shell structures that modify surface-interfacial electron transfer, to prepare structures that stabilize surface-bound chromophores and catalysts, and for the preparation of overlayer structures that stabilize electrodes for water oxidation and photocathodes for H-2 or CO2 reduction.
This study highlights a single-donor polymer which, when paired with an archetypal fullerene, polymer, and FREA, results in systems that are largely insensitive to donor Mn. Our results may have implications in polymer batch-to-batch reproducibility, in particular, relaxing the need for tight Mn control during synthesis.
