UTILIZATION OF N-TYPE SEMICONDUCTOR AND P-TYPE SEMICONDUCTOR

To utilize sunlight since an appearance surface part of a traffic vehicle has many opportunities of receiving sun beams during the daytime.SOLUTION: An electric non-conductive part is provided on an appearance surface part of a traffic vehicle. A paint in which a P-type semiconductor is mixed with a conductive paint is applied to a surface of the non-conductive spot. A paint in which an N-type semiconductor is mixed with an electric conductive paint is applied to portion in contact with the applied portion. The contact portion is a pn junction. The appearance surface part N-type semiconductor of the traffic vehicle is irradiated with sunlight and an electron moves to a hole of the P-type semiconductor from the N-type semiconductor. In this time, the generated current is taken out and utilized.SELECTED DRAWING: Figure 1 【課題】交通車両の外観表面部は、日中の太陽光線を受ける機会が多く、この太陽光を利用する。【解決手段】交通車両の外観表面部に電気不導体部を設け、この不導体場所の面にＰ型半導体を伝導性塗料と混合した塗料を塗布する。この塗布した部分に接してＮ型半導体を電気伝導性塗料と混合した塗料を塗布する。設した部分はｐｎ接合部となる。太陽光が交通車両の外観表面部Ｎ型半導体に照射され，Ｎ型半導体から電子がＰ型半導体の正孔に移動する。この際、発生した電流を取り出して利用するものである。【選択図】図１
