Despite major advances in solar energy technology, efficiency and cost remain obstacles to widespread market uptake. Collective oscillations in metallic nanoparticles that amplify the energy transferred to absorption materials could overcome current barriers.
Harnessing the Sun's radiation to produce electricity is an extremely sustainable way to power human activities. Technology that concentrates the solar energy can increase efficiency significantly. Luminescent solar concentrators (LSCs) could significantly reduce costs compared to large-area silicon-based devices and have the direct benefit of absorbing both direct and diffuse solar radiation so Sun tracking is not required.
