NOVELTY - The cell has a base substrate (10) i.e. p-type semiconductor substrate, including a pair of opposite surfaces (11, 12) and receiving sunlight incident on one of the surfaces, and a doping layer (101) i.e. n-type semiconductor layer, formed on the surface. A passivation layer (200) including hydrogen is formed on the doping layer. A capping layer (300) is formed on the passivation layer. The capping layer prevents discharge of the hydrogen from the passivation layer. An electrode (610) is arranged on the capping layer. Another electrode (620) is arranged on the other surface.    USE - Solar cell for converting sunlight energy into electrical energy by applying a photovoltaic effect.    ADVANTAGE - The passivation layer and the capping layer having a set of different refractive indices can function as double antireflection films, thus minimizing reflectivity of light incident on the passivation layer and the capping layer and reducing thickness of the base substrate, and hence decreasing manufacturing costs of the cell and simplifying manufacturing process of the cell. The cell reduces electron-hole recombination speed by forming the capping layer on the passivation layer including the hydrogen, where reflection of sunlight is reduced by the double antireflection films, thus providing a high-efficiency solar cell. The passivation layer and the capping layer are simultaneously formed with a same material to simplify a manufacturing process such that the base substrate can be deposited without flipping to reduce a layer depositing time and a layer exposing time to omit additional processes such as annealing process, to solve blistering problems.    DETAILED DESCRIPTION - The capping layer and the passivation layer are made of a carbon thin film. A back surface field (BSF) layer formed on the latter surface includes aluminum paste. INDEPENDENT CLAIMS are also included for the following:    (1) a method for manufacturing a solar cell    (2) a deposition device.
