PYROELECTRIC SOLAR TECHNOLOGY APPARATUS AND METHOD

摘要

A method to increase the efficiency of a solar cell comprises applying one of a transparent pyroelectric film and a plurality of films in a stack on a front surface of the solar cell and applying one of an opaque pyroelectric film and plurality of films in a stack on another surface of the solar cell. An electromotive force is generated to bias the solar cell such that an open circuit voltage is created. The method also includes increasing a short circuit current through the pyroelectric film. A constant temporal temperate gradient is created in the pyroelectric film to increase the short circuit current with a temperature. The method also includes biasing a p-n junction of the solar cell with the electromotive force produced from the pyroelectric film.
