Abstract
Carotenoids are natural pigments responsible for coloring in flowers and seeds. The semiconducting nature of carotenoids makes them a suitable candidate for solar harvesting and biodegradable nanoelectronic devices.
Highlights
Increasing demand for energy resources by human society and the depletion of conventional energy sources have made researchers think of renewable energy resources
Thereafter, we summarize some of the studies with carotenoid based nanowire, light-emitting diodes, transistors and light sensors
The carbon footprint is significantly shared by the electronic industry, i.e., manufacturing, transport, maintenance and e-waste disposal systems.[2,3,4,5,6]
Summary
Increasing demand for energy resources by human society and the depletion of conventional energy sources have made researchers think of renewable energy resources. Some of the breakdown products of carotenoids such as retinol (Vitamin A) have been found to improve human health upon consumption.[34] Several reviews have focussed on the applications of carotenoids, but they are mainly based on the current and potential use of carotenoids as functional foods, feed additive, pharmaceutical and health improvement products,[22,35,36] as colourants in food and textile industry[37,38,39] and as cosmetics and nutricosmetics.[40,41,42,43] to the best of our knowledge, there is no review study on the potential of carotenoids in solar energy harvesting and organic electronic devices. This review brings together the significant findings of this field, analyses the outcomes and persisting problems to find solutions for advancement of this technology
