Fabrication of a Spherical Silicon Solar Cell Module
Spherical silicon balls are applied to photovoltaic energy conversion. Silicon balls are produced by droplet spray method as well as abrasive machining of a single crystalline silicon wafer. A reflective mirror is used to maximize the solar cell efficiency. It is demonstrated the solar cell efficiency depends on the crystalline structure of silicon balls and the mirror in the module.
