Solar cell and method of forming the same

A method of forming a photovoltaic cell comprising:

• forming a first conductive film on a substrate;
• forming a photoelectric conversion layer on said first conductive film;
• forming a first groove through said photoelectric conversion layer and said first conductive film in order to divide said first conductive film;
• forming an opening through said photoelectric conversion layer and reaching to said first conductive film;
• forming a first insulating strip to fill said first groove;
• forming a second conductive film on said photoelectric conversion layer over said first insulating strip and making electrical contact with said first conductive film through said opening such that said second conductive film serially interconnects said first conductive film with another photovoltaic cell;
• and
• forming a second groove through said second conductive film in order to electrically divide said second conductive film, said opening being located between said first groove and said second groove.
