Abstract
An improved photovoltaic cell, and method for its manufacture, comprising front and back electrically conductive layers between which is sandwiched a primary light-absorbing layer of amorphous semiconducting material displaying low photogenerated carrier mobility below about 50 cm.sup.2 /V second, the constitution of which primary layer is fabricated to provide an affinity gradient reducing back-diffusion of a preselected species of photogenerated carrier (electrons or holes) to thereby forestall non-productive recombination with carriers of opposite type.
