The present invention provides an improved electrode structure for improving efficiency of solar cells, and the structure of the solar cells includes a back electrode, a transparent conducting glass layer, a photoelectric conversion layer, and a grid electrode. The transparent conducting glass layer includes a light-penetrated surface for accepting light. The photoelectric conversion layer is disposed between the back electrode and the transparent conducting glass layer to convert light energy into electric energy. The grid electrode is embedded in the transparent conducting glass layer to solve the problems of uneven electric potential for decreasing uneven voltage on the light-penetrated surface and further increasing efficiency of the solar cells.
