An apparatus and associated method of operation is provided for vapor deposition of a sublimated source material, such as CdTe, as a thin film on discrete photovoltaic module substrates that are conveyed in a continuous, non-stop manner through the apparatus. The non-directional roll textured surface provides a uniform matte finish to the lighting sheet. The entire circuit is powered from the input on the coaxial cable connection. The method also includes receiving a bid request from the user for the partial-disclosure informational lead being auctioned in the on-line auction. The semiconductor may further include a second doped layer formed over the first surface of the transparent layer.
