日本夏普公司研制成功一种10厘米见方的高效率多晶硅太阳能电池。由于电极与电池成直角,减少了对电极的电阻,且提高了输出电流。这种多晶硅太阳能电池的光转换率已达16.4％,居世界首位。目前,研究人员为了进一步扩大光入射面积,增加发电量,拟将电池表面的防反射光膜由原来的一层增至二成,以减少光的损失,缩小不吸收太阳光的电
Sharp Corporation of Japan has successfully developed a 10-cm square high-efficiency polysilicon solar cell. Since the electrode is at right angles to the battery, the resistance of the counter electrode is reduced, and the output current is increased. This polysilicon solar cell has a light conversion rate of 16.4%, ranking first in the world. At present, in order to further increase the light incident area and increase the amount of power generation, researchers plan to increase the anti-reflection film on the surface of the battery from the original layer to 20% so as to reduce the loss of light and reduce the amount of electricity that does not absorb sunlight.
