<p>Provided is an up-and-down type electrode structure of a solar cell plate, comprising a back electrode (4) and a front side gate electrode, wherein the back electrode (4) is distributed on the back side of the solar cell plate, the front side gate electrode is distributed on the front side of the solar cell plate, the front side gate electrode comprises mutually-parallel main gate lines (1) and a plurality of secondary gate lines (3) perpendicular to the main gate lines (1), there are three rows of main gate lines, each row of the main gate lines consists of two main gate lines, namely an upper main gate line and a lower main gate line which are separated via a horizontal interval (2), and the width of the horizontal interval (2) is 0.5 mm-4 mm. The up-and-down type electrode structure of a solar cell plate has a plurality of independent power generating units, and each of the independent units may be combined for use after being connected in parallel and also may be used as an independent power generating unit.</p> |
