日本TDK公司半导体能源研究所,最近研制出世界上转换率最高的PIN型非晶硅太阳能电池。这种太阳能电池的光电转换效率为12.65％。它由玻璃基板、透明电极、PIN半导体层和内部电极组成。为了提高转换效率,研究人员增加了透明电极表面凸凹形状最低点与最高点之间的距离,同时消除了电极之间的短路现象。这种太阳能电池的开放电压是0.885伏,短路电流密度为每平方厘米19.13毫安。
Japan TDK Semiconductor Institute of Energy, recently developed the world’s highest conversion rate of PIN-type amorphous silicon solar cells. The photoelectric conversion efficiency of this solar cell is 12.65%. It consists of a glass substrate, a transparent electrode, a PIN semiconductor layer and an internal electrode. In order to improve the conversion efficiency, the researchers increased the distance between the lowest point and the highest point of the concave-convex shape on the surface of the transparent electrode, and eliminated the short circuit between the electrodes. The open-circuit voltage of this solar cell is 0.885 volts, and the short-circuit current density is 19.13 mA per square centimeter.
