Abstract
We present a novel way to utilize high-concentration
photovoltaic (HCPV) radiative losses and diffuse light, otherwise
unused in conventional HCPV systems, to power an Imperial
College designed photoelectrochemical reactor (PECR) producing
H2 fuel through water splitting. A high efficiency photovoltaic
(HEPV) is embedded inside a Luminescent Solar Concentrator
(LSC). Edge emission from the radiative recombination loss
mechanism in the HEPV is guided within the LSC to the PECR
photocathode, whilst the LSC emitted light is guided to the
photoanode. The photon streams can be independently optimised
in intensity and wavelength. We demonstrate how photon streams
with balanced intensity can be achieved.
