Abstract

In this study, we tried to enhance the efficiency of solar hydrogen cells by using fluorescein, rhodamine B, and a combination of fluorescein with rhodamine B to coat an anode made by ZrO₂ absorbed sodium copper chlorophyll molecules. Fluorescein and rhodamine B are utilized to convert blue light and green light into red light, which is in turn absorbed by sodium copper chlorophyll, causing photoelectrons to be generated onto ZrO₂. This photon down-conversion mechanism increases the spectrum of solar light absorbance. According to the photon down-conversion mechanism, the efficiency of solar hydrogen production can be enhanced by absorbing more photons with different wavelengths in the visible light regime. The highest efficiency of hydrogen generation under air mass 1.5 global (AM 1.5 G) illumination (solar simulator) was 0.058 ml/cm²-h when a ZrO₂ nanoparticles layer was coated with sodium copper chlorophyll and rhodamine B.
