Abstract: A high efficiency configuration for a solar cell module comprises solar cells arranged in a shingled manner to form super cells, which may be arranged to efficiently use the area of the solar module, reduce series resistance, and increase module efficiency. Each super cell comprises a plurality of rectangular or substantially rectangular silicon solar cells arranged in line with long sides of adjacent silicon solar cells overlapping and conductively bonded directly to each other to electrically connect the silicon solar cells in series. A super cell may comprise a hidden tap contact pad located on a back surface of a solar cell located at an intermediate position along the super cell. In some variations the overlapping sides of adjacent silicon soar cells in a super cell are flexibly bonded to each other, and a flexible electrical interconnect is rigidly bonded to one of the solar cells.

Abstract: A solar cell includes a semiconductor substrate, one or more bus bar electrode, and a plurality of finger electrodes. The bus bar electrode and the finger electrodes are disposed on the semiconductor substrate. Conventionally, in a process of forming the finger electrodes by utilizing screen printing, offset may occur. Consequently, the finger electrodes cannot be connected to the bus bar electrode. According to the provided solar cell, the bus bar electrode is formed by using patterned silver and aluminum, to manufacture a wider bus bar electrode than the bus bar electrode in the conventional solar cell without increasing silver consumption, thereby resolving the problem of offset.
