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.

Abstract
A solar cell comprises a semiconductor substrate and at least one bus electrode and a plurality of finger electrodes disposed on the semiconductor substrate. In the conventional process of forming the finger electrodes by screen printing, misalignment may occur, so that the finger electrodes cannot be connected to the bus electrodes. The utility model forms the bus electrodes by using patterned silver and aluminum, and produces a bus electrode wider than the bus electrode of a conventional solar cell without increasing the amount of silver, thereby solving the above-mentioned misalignment problem.
