In this review, we begin by discussing the need for harnessing renewable energy resources in the context of global energy demands. A summary of first- and second-generation solar cells, their efficiency and grid parity is provided, followed by the need to reduce material and installation costs, and achieve higher efficiencies beyond the Shockley–Queisser limit imposed on single junction cells. We also discuss the specific advantages offered by nanomaterials in enhanced energy harvesting, what…
