NOVELTY - The cell has multiple unit cells (200) connected together electrically, where each unit cell comprises two electrode layers (21, 22) and two photoconductive layers (23, 24) sequentially stacked together. A set of grooves (210) is formed in the electrode layer (21), and another set of grooves (220) is formed through the photoconductive layer (24). Multiple recesses (255) are formed at intersections between the interlayer and the latter set of grooves by an etching method for preventing leakage of electrical current from the photoconductive layers to the interlayer through the latter grooves.    USE - Stacked-layered thin film solar cell.    ADVANTAGE - The cell prevents current leakage from the grooves to the interlayer, thus achieving excellent insulation effects. The recesses provide better insulating effects than the circuit-breaking grooves, so that insulation can be enhanced at a lower production cost.    DETAILED DESCRIPTION - The etching method is a vapor/liquid etching method that uses vapor/liquid of a substance selected from a group consisting of hydrochloric acid, oxalic acid, sulfuric acid, acetic acid, hydrofluoric acid and nitric acid. The electrode layers and the interlayer are made of a transparent conductive oxide selected from a group consisting of tin dioxide, indium tin oxide, zinc oxide, aluminum zinc oxide, gallium-doped zinc oxide and indium zinc oxide. The former and the latter electrode layers comprise a metal layer of a material selected from a group consisting of silver, aluminum, chromium, titanium, nickel and gold. The photoconductive layers are made of a material selected from a group consisting of monocrystalline silicon, polycrystalline silicon, amorphous silicon, microcrystalline silicon, germanium, silicon-germanium and silicon carbide. An INDEPENDENT CLAIM is also included for a method for manufacturing a stacked-layered thin film solar cell.
