Electrode construction for enhancing photoelectric transforming efficiency of silicon solar cell

The invention discloses an electrode structure for improving a crystal silicon solar battery photoelectric transformation efficiency characterized by arranging parallely set gate lines on a light interception face of the crystal silicon solar battery substrate, and arranging at least two solder joints between each gate line and the crystal solar battery substrate light interception face, wherein the gate lines are conductive gate lines. The invention cancels split-gate lines in a background technique, uses the solder points between the metal gate lines and the crystal solar battery substrate to gather light currents of the crystal silicon solar battery light interception face and guides the currents gathered by the solder points by using the metal gate lines. Because said structure, the invention not only reduces a lightproof area of the light interception face gate line of the crystal silicon solar battery, but also reduces a series resistance of the crystal silicon solar battery, thereby improving the conversion efficiency of the crystal silicon solar battery and facilitating the interconnect of multi-block single batteries.
