摘要： A method of manufacturing a solar cell comprises interposing an intermediate layer containing p-type or n-type impurity between a silicon thin film and a support substrate, and heating all or part of the structure thus formed to a temperature at which the impurity contained in the intermediate layer diffuses into the silicon thin film, forming a high-concentration impurity layer in the silicon thin film.

摘要： The problem addressed by the present invention is providing a technique for fabricating, by a method simpler than conventional methods, a silicon substrate that is effective for light trapping, one surface of which has a textured structure and the other surface of which has higher reflectivity than the surface having the textured structure. The fabrication method for this semiconductor substrate comprises: a sandblasting step in which a first surface of a silicon substrate in an as-sliced state, fabricated by slicing a silicon ingot, is surface treated by sandblasting and, after the sandblasting step, a step for carrying out surface treatment using an etching solution that contains either or both of hydrofluoric acid and nitric acid on the silicon substrate.

摘要： A photoelectric element includes a first region having a light-receiving surface. A second region having a short side length not greater than twice the minority carrier diffusion length of the first region is provided on at least one portion of the first region to form a photovoltaic mechanism in conjunction with the first region. A barrier layer is provided to cover at least those portions of the light-receiving surface of the first region not covered by the second region, and a transparent conductive film is provided on the barrier layer and electrically connected to at least one second region. The voltage of the second region generated by incident light is applied through the transparent conductive film to the light-receiving surface of the first region to produce an electric field in the direction inducing majority carriers.
