ELECTRODE STRUCTURE AND SOLAR CELL USING THE SAME

摘要

An electrode structure is disclosed in the present invention and includes a first conductive electrode and a second conductive electrode. The first conductive electrode includes a first busbar electrode member and a first finger electrode member. A portion of the first busbar electrode member above a first diffusion pattern is electrically contacted with the first diffusion pattern by first contact points. A portion of the second busbar electrode above a second diffusion pattern is electrically contacted with the second diffusion pattern by second contact points. The first finger electrode and the second finger electrode are respectively and electrically contacted with the first diffusion pattern and the second diffusion pattern.
