Abstract
Disclosed are a stacked-layered thin film solar cell and a manufacturing method thereof. The stacked-layered thin film solar cell includes plural unit cells connected together electrically, each including a substrate, a first electrode layer, a first photoconductive layer, an interlayer, a second photoconductive layer and a second electrode layer, wherein the first electrode layer is divided by plural first grooves; plural second grooves are formed through the second photoconductive layer, the interlayer, and the first photoconductive layer; and plural third grooves are formed in the second electrode layer and extended downward through the first photoconductive layer. The first, second and third grooves are offset with respect to one another. The stacked-layered thin film solar cell is characterized by plural recesses formed at intersections between the interlayer and the second grooves for preventing leakage of electrical current from the first or second photoconductive layer to the interlayer through the second grooves.
