Nonaqueous Electrochemical Photovoltaic Cells Based on n-GaAs and n-Si

摘要

The photoelectrochemical properties of n-GaAs and n-Si are compared in nonaqueous electrolytes. Si is the more sensitive material to surface treatment, and is more prone to anodic passivation. Surface adsorption of Ru or basic heterocyclic polymers greatly improves photocurrent yields for both materials, possibly due to a complexation of surface states. (Author)
