<p>PROBLEM TO BE SOLVED: To expand the usable field of a solar battery and, in addition, to enable the battery to highly efficiently generate power by giving softness and a strength to crystalline silicon by forming silicon in a fibrous shape, and, at the same time, to enable the battery to simultaneously absorb visible rays and infrared rays by combining crystalline n-type silicon with i- and n-type amorphous silicon. SOLUTION: This solar battery is manufactured in such a structure that the battery absorbs both visible rays and infrared rays by arranging n-type silicon 1 which is made to have softness by extracting crystalline silicon in a fibrous shape from a solution dissolving crystalline silicon in a ribbon-like form or by knitting the fibrous silicon and forming an electrode by laminating the i-type amorphous silicon 2 and p-type amorphous silicon 3 upon silicon 1. The quantity of materials used in this solar battery is reduced as compared with the conventional battery and, since the surface area, namely, the light receiving area per unit fiber is increased due to the fibrous crystalline silicon, this battery is improved in power generating efficiency. In addition, since the crystalline silicon is combined with the amorphous silicon, the battery can absorb visible rays and infrared rays, and the power generating efficiency of the battery is further improved.</p> |
