SOLAR CELL

摘要

A solar cell includes a photovoltaic substrate having a first surface and a second surface and a plurality of bus bar electrode net structures. The bus bar electrode net structures are separately disposed on the first surface, each bus bar electrode net structure includes a bus bar electrode, a plurality of finger electrodes, at least one connecting line electrode and at least one vertical finger electrode. The bus bar electrode is disposed on the first surface. The finger electrodes are separately disposed at two sides of the bus bar electrode. The connecting line electrode is disposed on the first surface. Each connecting line electrode connects with ends of at least two finger electrodes. The vertical finger electrode is disposed on the first surface, and is parallel to the bus bar electrode and disposed between the two ends of the finger electrode to connect with at least two adjacent finger electrodes.
