    摘要: The present invention provides a semiconductor based photovoltaic device and a manufacturing method thereof. The semiconductor based photovoltaic device is able to absorb light with a wide band wavelength, and has high photoelectric conversion efficiency since it has high electron-hole pair separation efficiency. More specifically, the method for manufacturing the photovoltaic device comprises the steps of: a) forming a thin semiconductor quantum dot film on a p or n-type semiconductor substrate, wherein the thin semiconductor quantum dot film includes semiconductor quantum dots inside a medium at which the same type of impurities as the semiconductor substrate are doped; b) forming a pore array through partial etching, wherein the pore array penetrates the thin semiconductor quantum dot film; c) depositing a semiconductor in which complementary impurities to the semiconductor substrate are doped on the thin semiconductor quantum dot film at which the pore array is formed; and d) forming sequentially a transparent conductive film and an upper electrode on the semiconductor in which the complementary impurities are doped and forming a lower electrode at a lower portion of the semiconductor substrate.
