摘要：
The photoelectrolysis of HBr and HI using a p-GaInP2(Pt)/GaAs photoelectrochemical/photovoltaic device is demonstrated. The device is a photoelectrochemical cell, voltage-biased with an integrated photovoltaic device. This device splits these acids directly on illumination, using light as the only energy input. Additionally, for these compounds, the device can simultaneously produce electrical energy. The HBr and HI decomposition efficiency for this system, based on the short-circuit current and the chemical potential of each compound, is 8.1 and 2.6%, respectively. The total conversion efficiency, including the cogenerated electrical energy, is 11.2 and 9.65%, respectively. (C) 1999 The Electrochemical Society. S1099-0062(99)02-011-8. All rights reserved.
