Towards compact solar thermionic converters based on carbon nanotubes forests

One of the conceptually simplest ways of conversion of solar energy to electricity is based on thermionic emission. This process can occur in carbon nanotube forests through the Heat Trap effect, whereby a small amount of focused light results in unusually localized and thus extremely efficient heating. Here, we exploit this phenomenon to build a new generation of simple and compact solar thermionic converters, exploring the design issues involved in making practical prototypes and systematically improving their performance.
