A close spaced planar vacuum diode is constructed with a photoemissive first electrode and a low work function second electrode. As a result of photon flux on said photoemissive first electrode, electrons are emitted into the vacuum space and travel to said second electrode. This electron current may then flow through an external load, powering said external load.
