Abstract
A method of generating electricity from light, that uses a photovoltaic array, that includes a junction between an inorganic electron-donating layer and an inorganic electron-accepting layer. The electron-donating layer includes moieties which after photon activation have unpaired electrons, and wherein some of the electrons are freed when light strikes the electron-donating layer, thereby transforming the moieties into free radicals or equivalents but many of the freed electrons recombine. Also, many of the free radicals or equivalents in the triplet state are optimally responsive to a selective magnetic field that has been determined to optimally increase the lifetime of the triplet state of the free radicals and thereby forestall recombination of the freed electrons into the free radicals. A magnetic field of substantially the optimal strength that is substantially unvarying over the electron donating layer is created as the array is being exposed to light.
