Abstract:
A method of producing a photovoltaic panel, comprising the steps of:forming a plurality of holes through a thickness of a first electrode plate including an electrically insulating layer and an electrically conductive layer which are superposed on each other, fitting, in said plurality of holes, a plurality of photovoltaic elements, respectively, each of which has a P-N junction between a core portion thereof and a shell portion thereof, removing a first portion of the shell portion of said each photovoltaic element that is located on the side of the insulating layer of the first electrode plate, so that a second portion of the core portion of said each photovoltaic element that corresponds to said first portion of the shell portion is exposed, electrically connecting a third portion of the shell portion of said each photovoltaic element to the conductive layer of the first electrode plate, and electrically connecting an end portion of said exposed, second portion of the core portion of said each photovoltaic element, to a second electrode plate, such that each of the holes formed through the thickness of the first electrode plate provides an annular vacant space which surrounds an annular remaining portion of said exposed second portion of the core portion, and accordingly said annular remaining portion of said exposed second portion of the core portion does not directly contact the electrically insulating layer of the first electrode plate.
