Abstract

A new type of solar cell of potentially higher efficiency is presented. It is based in a intermediate band that acts as a relay to allow two energy photons with less energy than the bandgap to pump one electron from the valence band to the conduction band. Alloys for obtaining the intermediate band material using a compound semiconductor in which an additional element is introduced are the object of a research based on advanced band theory calculations. Alternatively, arrays of quantum dots may also form an intermediate band. If produced by MBE they seem a simpler way of fabricating prototypes to prove the principle of operation. Experimental work along this line is in progress
