Abstract

A simplified method for fabricating a solar cell device is provided. The solar cell device has silicon nanowires (SiNW) grown on an upgraded metallurgical grade (UMG) silicon (Si) substrate. Processes of textured surface process and anti-reflection thin film process can be left out for further saving costs on equipment and manufacture investment. Thus, a low-cost Si-based solar cell device can be easily fabricated for wide application.
