High performance single crystal silicon cells and arrays thereof are manufactured using a rapid process flow. Tunneling junctions formed in the process provide performance benefits, such as higher efficiency and a lower power temperature coefficient. The process generates a large array of interconnected high performance cells smaller than typical cells without requiring additional process steps, and simplifies integration of these coupons into the final product. The cells can have different shapes, sizes, and orientations, enabling the array to be flexible in any desired direction. Higher efficiencies and lower hot spotting under shading is achieved by connecting small low current, high voltage cells in dense series and parallel configurations. Low current cells also require much less metallization than typical solar cells and arrays.

A method for producing a thin-film solar module with serially connected solar cells and related device. A back electrode layer is deposited on one side of a flat substrate and subdivided by first patterning trenches. An absorber layer is deposited over the back electrode layer and subdivided by second patterning trenches. A front electrode layer is deposited over the absorber layer. At least the front electrode layer is subdivided by third patterning trenches. A direct succession of a first patterning trench, a second patterning trench, and two adjacent third patterning trenches forms a patterning zone. The third patterning trenches are produced by laser ablation through a pulsed laser beam, where one third patterning trench is produced with laser pulses of higher energy and the other third patterning trench of the patterning zone is produced with laser pulses of lower energy.

A photoelectric conversion element includes: a first photoelectric conversion layer including: a bottom electrode; a photoelectric conversion layer; and a top electrode; and a second photoelectric conversion part including: a bottom electrode; a photoelectric conversion part; and a top electrode. A conductive layer is formed on the bottom electrode. The top electrode and the bottom electrode are electrically connected by a conductive portion and the conductive layer. The conductive portion is formed of a part of the top electrode filled in a first groove that makes a surface of the conductive layer exposed and separates a photoelectric conversion layer and a photoelectric conversion layer from each other. The top electrodes are physically separated by a second groove provided to make a step surface of a stepped portion provided in the photoelectric conversion layer exposed and have a bottom surface thereof overlap the surface of the conductive layer.
