Mimicking photosynthesis and producing solar fuels is an appealing way to store the huge amount of renewable energy from the sun in a durable and sustainable way. Various technologies exist with different readiness levels [1]. A variety of solar fuels can also be produced, including hydrogen but also syngas or methane. In that context, we will exploit data from our recent contributions regarding the preparation of photoelectrode materials and the design of tandem photoelectrochemical cells [2], but also artificial leaves [3] and integrated PV-EC cells to benchmark these approaches and propose a path forward for solar fuels technologies.
