Enhanced Photoemission for Energy and Diamondoid Materials

Thermionic emission has long been an attractive idea for thermal energy conversion for its potentially high-efficiency conversion with no moving parts and simple device geometry. Concentrated solar thermal applications have a considerable quantity of both heat and light present, which might be harvested efficiently using photon-enhanced thermionic emission (PETE), that can benefit from both photon illumination and thermal energy. Here we show that recombination can be greatly reduced and yield increased by going to thinner films and heterostructure material architectures. We will then turn towards enhancing photoemission with protected diamondoid monolayers, and new materials possible through diamondoid self assembly.
