Abstract

Read online

Unassisted water splitting by tandem photoelectrochemical and photovoltaic devices requires optimization of the absorbance and transmittance properties of the front photoelectrode. Here, Shi et al. use a conductive distributed Brag reflector to harvest photons of different wavelengths in the two subcells.
