Abstract

A photoelectrochemical solar cell based on an n-GaAs/polymer-redox-electrolyte junction is reported. Di(ethylene glycol)ethyl ether acrylate containing ferrocene as a redox species and benzoin methyl ether as a photoinitiator is polymerized in situ. Propylene carbonate is used as a plasticizer to improve the conductivity of the polymer redox electrolyte. For thin (1 μm) polymer electrolytes, the series resistance of the cell is neglible. However, the short-circuit photocurrent density of the cell at light intensities above 10 mW/cm² is limited by mass transport of redox species within the polymer matrix. At a light intensity of 70 mW/cm², a moderate light-to-electrical energy conversion efficiency (3.1%) is obtained. The interfacial charge-transfer properties of the cell in the dark and under illumination are studied.
