NOVELTY - Solar cell (400) comprises: a substrate (410); a first conductive layer (420) disposed on the substrate; a photovoltaic layer (430) for generating electron-hole pairs when being irradiated by a light ray; a second conductive layer (440) disposed on the photovoltaic layer; and at least one passivation layer, disposed on at least one of the positions between the first conductive layer and the photovoltaic layer, between the doped films in the photovoltaic layer and between the photovoltaic layer and the second conductive layer.    USE - Used as solar cell.    ADVANTAGE - The solar cell: has improved photoelectric conversion efficiency, by reducing the chance of surface recombination of the electron-hole pairs; has passivation layer, which can be formed using simplified process.    DETAILED DESCRIPTION - Solar cell comprises: a substrate; a first conductive layer disposed on the substrate; a photovoltaic layer for generating electron-hole pairs when being irradiated by a light ray, where the photovoltaic layer is disposed on the first conductive layer and has many doped films; a second conductive layer disposed on the photovoltaic layer; and at least one passivation layer, disposed on at least one of the positions between the first conductive layer and the photovoltaic layer, between the doped films in the photovoltaic layer and between the photovoltaic layer and the second conductive layer, so as to reduce the chance of surface recombination of the electron-hole pairs on at least one surface of the photovoltaic layer. An INDEPENDENT CLAIM is also included for a method for manufacturing the solar cell, comprising: providing a substrate; forming a first conductive layer on the substrate; forming, on the first conductive layer, a photovoltaic layer having many doped films, where the photovoltaic layer generates electron-hole pairs when being irradiated by a light ray; forming a second conductive layer on the photovoltaic layer; and forming a passivation layer on at least one of the positions between the first conductive layer and the photovoltaic layer, between the doped films in the photovoltaic layer and between the photovoltaic layer and the second conductive layer, so as to reduce the chance of surface recombination of the electron-hole pairs on at least one surface of the photovoltaic layer.
