日本大阪大学工程科学系坪村教授研究了一项湿式光电池的基本技术,这种光电池能借助于浸泡在溶液中的半导体材料而将辐射能转换成电能。当当浸泡于液体中时,半导体表面的快速氧化却有碍于电池功效的发挥。 为了克服这一缺点,采用如下方法:(1)在半导体表面涂敷一薄层如钨那样的金属,以防止氧 Professor Ping Village, Department of Engineering Science, Osaka University, Japan studied the basic technology of a wet-type photovoltaic cell that converts radiant energy into electrical energy by means of a semiconductor material immersed in a solution. When immersed in a liquid, the rapid oxidation of the semiconductor surface is hindered by the performance of the battery. In order to overcome this disadvantage, the following methods are used: (1) A thin layer of a metal such as tungsten is coated on the surface of the semiconductor to prevent oxygen
