PURPOSE:To allow each pin element to absorb sufficient amount of light by partially employing a double-layered structure for the incident direction of light and forming electrically the same connecting method as the triple-layered structure. CONSTITUTION:A first, second and third pin elements 2-4, which are sequentially formed having the partially overlapping regions, are formed on a substrate and these three pin elements 2-4 are electrically connected in series. Thereby, the second pin element and the third pin element 4 simultaneously absorb the incident light and generate the power and the first pin element 2 absorbs the light having passed the respective elements and generates the power. Namely, the first, second and third pin elements 2, 3, 4 are not connected electrically in parallel but in series with a transparent insulation layer arranged between respective pin elements and show the photovoltaic characteristic of a triple layered structure. |
