Abstract

The need to develop sustainable energy solutions is an urgent requirement for society, with the additional requirement to limit dependence on critical raw materials, within a virtuous circular economy model. In this frame-work, it is essential to identify new avenues for light-conversion into clean energy and fuels exploiting largely available materials and green production methods. Metal oxide semiconductors (MOSs) emerge among other spe-cies for their remarkable environmental stability, chemical tunability, and optoelectronic properties. MOSs are often key constituents in next genera-tion energy devices, mainly in the role of charge selective layers. Their use as light harvesters is hitherto rather limited, but progressively emerging. One of the key strategies to boost their properties involves doping, that can improve charge mobility, light absorption and tune band structures to maximize charge separation at heterojunctions. In this review, effective methods to dope MOSs and to exploit the derived benefits in relation to performance enhancement in different types of devices are identified and critically compared. The work is focused specifically on the best opportuni-ties coming from the use of non-critical raw materials, so as to contribute in defining an economically feasible roadmap for light conversion technolo-gies based on these highly stable and widely available compounds.
