Abstract
A method to increase the efficiency of a solar cell comprises depositing a pyroelectric film on a surface of the solar cell and generating an electromotive force to bias the solar cell. The method also includes creation of an open circuit voltage. Further, the method includes increasing a short circuit current through the pyroelectric film and creating a sustained temperature variation in the solar cell. A constant temporal temperate gradient is created in the pyroelectric film to increase the short circuit current with a temperature. Further, a p-n junction is biased with the electromotive force produced from the pyroelectric film.
