Breakthrough discoveries in high-throughput formulation of abundant materials and advanced engineering
approaches are both in utter need as prerequisites for developing novel large-scale energy conversion
technologies required to address our planet’s rising energy demands. Nowadays, the rapid deployment of
Internet of Things (IoT) associated with a distributed network of power-demanding smart devices,
concurrently urges for miniaturized systems powered by ambient energy harvesting. Graphene and other
related two-dimensional materials (GRM) consist a perfect fit to drive this innovation owing to their
extraordinary optoelectronic, physical and chemical properties that emerge at the limit of two-dimensions.
In this review, after a critical analysis of GRM’s emerging properties that are beneficial for power generation,
novel approaches are presented for developing ambient energy conversion devices covering a wide range
of scales. Notable examples vary from GRM-enabled large-scale photovoltaic panels and fuel cells, smart
hydrovoltaics and blue energy conversion routes, to miniaturized radio frequency, piezoelectric, triboelectric,
and thermoelectric energy harvesters. This presentation will focus on GRM-enabled energy
harvesters that have the potential to revolutionize the way that grid-electricity is provided in the cities of the future. At the end of the discussion, perspectives on the trends, limitations and commercialisation potential of these emerging, up-scalable energy conversion technologies are provided.
