PURPOSE:To improve power generation efficiency, by installing an organic solar battery in the manner in which the battery surface is inclined to incident ray. CONSTITUTION:In an organic solar battery 01, an N-type organic semiconductor 3, a P-type semiconductor 2, and a metal electrode 5 are formed on an ITO transparent electrode substrate 4 by vacuum evaporation. A glass plate 5 is fixed on the electrode substrate 4. The organic solar battery 01 is fixed on a retaining stand 11 by a fixing plate 12, at an inclination angle alpha=60 deg.. The traveling distance of the ray passing the vicinity of the interface of the P-layer 2 and the N-layer 3 becomes long in the case of oblique ray (b), as compared with vertical ray (a). Hence the absorption efficiency in this part is increased, and power generation efficiency can be improved. |
