Disclosed herein is an automotive solar cell roof panel which may be manufactured by adjusting the width and number of cells according to a transparent part and an opaque part in one solar cell module, thus improving output and simplifying a structure. The first and second solar cells include a plurality of transparent-part cells and a plurality of opaque-part cells whose widths and numbers are adjusted according to a current density and a voltage ratio. As such, it is unnecessary to array different kinds of solar cells with different voltage or current ranges, thus maximizing output in one solar cell module, and an additional wiring structure for individually controlling output power, an additional converter, and additional control for voltage matching may not be required, thus simplifying a process.

The invention concerns a method of manufacturing a photovoltaic module comprising at least two electrically connected photovoltaic cells, each photovoltaic cell (4.sub.i) being multi-layered structure disposed on a substrate (6) having down-web direction (X) and a cross-web direction (Y). The method comprises providing a plurality of spaced-apart first electrode strips (8.sub.i) over the substrate (6), each first electrode strip extending along the cross-web direction (Y), and providing, over the first electrode strips layer, at least one insulating strip (14a, 14b) of an insulator material extending along the down-web direction (X), each insulating strip defining a connecting area and an active area. A functional stack (20) comprising a full web coated layer of photoactive semiconductor material is formed over the first layer and within the active area. A plurality of spaced-apart second electrode strips (28.sub.i) are provided within the active area, each second electrode strip extending along the cross-web direction (Y), so as to form photovoltaic cells and a photovoltaic module is formed by electrically connecting at least two adjacent photovoltaic cells, by extending over the insulating strips (14a, 14b) electrical connection patterns to electrically connect, within the connecting area(s), the second electrode strip of an photovoltaic cell to the first electrode strip of an adjacent photovoltaic cell.

A solar cell includes elements, a connecting portion, and a transparent portion. The elements include first and second elements arrayed in a first direction. The transparent portion is located between the connecting portion and the second element. Each of the elements includes first and second electrode layers and a semiconductor layer interposed between the first and second electrode layers. Between the first element and the second element, their first electrode layers sandwich a first gap and their second electrode layers sandwich a second gap shifted in the first direction from the first gap.
