NOVELTY - Increasing the efficiency of a solar cell (102) comprises: depositing a pyroelectric film on a surface of the solar cell; generating an electromotive force to bias the solar cell where an open circuit voltage is created; increasing a short circuit current through the pyroelectric film; creating a sustained temperature variation in the solar cell; creating a constant temporal temperate gradient in the pyroelectric film to increase the short circuit current with a temperature; and biasing a p-n junction of the solar cell with the electromotive force produced from the pyroelectric film.    USE - The method is useful to increase the efficiency of a solar cell, which is useful in a photovoltaic power generation apparatus (claimed), machine-readable medium and/or a machine accessible medium compatible with a data processing system (e.g. computer devices).    ADVANTAGE - The method: reduces the resistance of the material which increases the current that increases the power; and provides continuous increase in the short circuit current through the solar cell.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a solar cell comprising: a pyroelectric film; a semiconductor device provided directly on a surface of the solar cell; and the pyroelectric film deposited on the surface of the solar cell comprising the semiconductor device; and    (2) a photovoltaic power generation apparatus comprising: a solar cell; a current collecting wiring provided on at least one of a transparent pyroelectric film (104) and an opaque pyroelectric film (106); a semiconductor device provided directly on the current collecting wiring; the transparent pyroelectric film deposited on a first side of the solar cell; and the opaque pyroelectric film deposited on a second side of the solar cell.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a solar cell with pyroelectric film.
