HIGH PERFORMANCE PHOTO-THERMIONIC SOLAR CONVERTERS

摘要

A photo-converter device which converts incident electromagnetic radiation on a radiation receiving surface into electrical current, comprising: at least one cell, comprising: a cathode separated by a gap from an anode, such that electrons emitted by said cathode travel on average along a first direction from said cathode to said anode through said gap, wherein the radiation receiving surface is a surface of the cathode, with an average direction of orientation which is not facing or opposite said gap.
