介绍了基于硅纳米线的金属箔太阳能电池。讨论了这种器件的主要优点，然后讨论了采用沉积在纳米线阵列上的薄非晶硅层形成pn结的电池设计的光学反射率，电流电压和外部量子效率数据。在1.8 cm(2)的电池中获得了类似于1.6 mA/cm(2)的电流密度，并且在690 nm处测量了广泛的外量子效率，最大值接近12%。与平面电池相比，硅纳米线太阳能电池的光学反射率降低了一到两个数量级。(c) 2007年美国物理学会。
Silicon nanowire-based solar cells on metal foil are described. The key benefits of such devices are discussed, followed by optical reflectance, current-voltage, and external quantum efficiency data for a cell design employing a thin amorphous silicon layer deposited on the nanowire array to form the p-n junction. A promising current density of similar to 1.6 mA/cm(2) for 1.8 cm(2) cells was obtained, and a broad external quantum efficiency was measured with a maximum value of similar to 12% at 690 nm. The optical reflectance of the silicon nanowire solar cells is reduced by one to two orders of magnitude compared to planar cells. (c) 2007 American Institute of Physics.
