Method of manufacturing amorphous photovoltaic-cell module

DETAILED DESCRIPTION This invention has been made in order to solve the above problems, and has for its object the provision of a method of manufacturing an amorphous photovoltaic-cell module which is suited to automation and mass production by lessening the number of locations of electrical connection among the amorphous photovoltaic cells.
The method of manufacturing an amorphous photovoltaic-cell module according to this invention comprises the steps of forming an amorphous film on an elongate lower electrode except for narrow portions on both sides thereof, subsequently forming a film of a transparent upper electrode on said amorphous film and thereafter forming a large number of digitated collectors on said transparent upper electrode, thereby to prepare a unitary amorphous photovoltaic cell, the step of cutting said unitary amorphous photovoltaic cell into predetermined geometries and dimensions, and the step of electrically connecting in series the collector of each individual amorphous photovoltaic cell defined in the previous cutting step and the exposed narrow parts of said lower electrode of the adjacent individual amorphous photovoltaic cell.
In this invention, amorphous photovoltaic cells of great width and large area can be electrically connected by a very simple expedient, so that the labor required for the arrayal and connection of the amorphous photovoltaic cells decreases sharply.
In addition, the effective area of the amorphous photovoltaic cell increases, so that an amorphous photovoltaic-cell module of high photoelectric efficiency can be manufactured.
