In recent years, with enormous advantages of carrier collection and light absorption, Si nanowire solar cells offer a potential to replace the bulk silicon solar cells. At present, there are still some problems of SiNWs solar cells. For instance, normal metal grid would shade around 10% of surface areas which limit the light absorption, especially in the SiNWs solar cell because of more areas in 3D nanowire structure. To improve the performance, better front electrode need to be pursue. A new method micro-grid metal contact was investigated here to enhance the front contact but not reduce light absorption.
