The conversion efficiency of PV systems is a significant factor when considering the overall efficacy of solar hydrogen production. As technology advances, efforts to enhance solar panel performance continue, with researchers exploring tandem solar cells and alternative materials such as perovskite to improve energy capture rates. The objective remains to maximize the solar-to-electric conversion efficiency, thus theoretically increasing the hydrogen yield in associated electrolysis systems.

4. THERMOCHEMICAL WATER SPLITTING

While electrolysis remains a prominent method, thermochemical water splitting offers another innovative approach to hydrogen extraction from solar energy. Unlike electrolysis, which operates through electrical input, thermochemical processes utilize high temperatures to dissociate water molecules. These processes often involve multiple steps and chemical reactions that can harness concentrated solar power.

One of the notable methods within thermochemical water splitting is the use of metal oxide cycles, involving materials that can withstand high temperatures. These reactants undergo thermochemical reactions to produce hydrogen as a byproduct. This method showcases a promising avenue for hydrogen production, especially in regions receiving ample sunlight to facilitate necessary high temperatures, ensuring efficiency throughout the energy conversion process.
