我们提出采用铝和金金属的晶体硅太阳能电池。 P 型基板涂有 100 nm 厚的热生长 SiO 2 层。将顶部SiO 2 层减薄至约1.5nm。 Al 和 Au 的条纹在顶面上形成，间隙为 0.29 mm，以便由于功函数之间的差异而在硅中产生内部内置电势。通过21.7mW/cm 2 的卤素灯照明来观察太阳能电池特性。短路电流密度、开路电压和填充因子为5.8mA/cm 2 、0.49V和0.57。转换效率为7.5%。通过隧道效应，光生空穴和电子分别流入 Au 和 Al 电极。
We propose crystalline silicon solar cells with Al and Au metals. P-type substrates were coated with 100-nm-thick thermally grown SiO 2 layers. The top SiO 2 layer was thinned to about 1.5 nm. Stripes of Al and Au were formed with a gap of 0.29 mm on the top surface in order to cause an internal built-in potential in silicon because of the difference between their work functions. Solar cell characteristics were observed by halogen lamp illumination at 21.7 mW/cm 2. The short-circuit current density, open-circuit voltage, and fill factor were 5.8 mA/cm 2, 0.49 V, and 0.57. The conversion efficiency was 7.5%. Photo-induced holes and electrons flowed into Au and Al electrodes, respectively, by the tunneling effect.
