000905137 520__ $$aWe study the effects of simulated outdoor illumination conditions on the performance of photovoltaic-biased electrosynthetic (PV?EC) systems used for the generation of hydrogen by means of solar water splitting. An integrated PV-EC cell consists of a photovoltaic cell (PV) directly combined with an electrolysis cell (EC), where the chemical reactions take place. In the present work, multijunction silicon based solar cells [1] were implemented for the PV part of the device together with an EC cell using a Pt/IrOx catalyst system. Annual variations in the solar illumination spectra influence the device performance together with long-term energy conversion. Both PV device and PV-EC device performance under varied spectral conditions differ from the performance obtained under standard AM1.5G illumination. Our model accounts for annual spectral changes in illumination and predicts the long-term (1 year) performance of PV?EC systems in terms of the hydrogen amount produced for a given geographical location for various types of multijunction photovoltaic systems (tandem, triple, and quadruple junctions).
