Title: Innovations of Chien-Chang Chao in Solar Cell Technology

Introduction

Chien-Chang Chao is a notable inventor based in Taoyuan County, Taiwan. He has made significant contributions to the field of solar cell technology, holding 2 patents that enhance the efficiency and effectiveness of solar energy systems. His work focuses on innovative methods for fabricating electrodes in silicon solar cells.

Latest Patents

Chao's latest patents include a method for fabricating silicon-doped or boron-doped aluminum electrodes. This method involves arranging an aluminum target or paste, selectively doped with silicon and/or boron, at a silicon wafer with a passivation layer. The doped aluminum layer is then melted in a linear or dot pattern, allowing it to pass through the passivation layer and contact the silicon wafer. This process reduces contact resistance between the aluminum back electrode and the silicon wafer, ultimately improving the energy conversion efficiency of crystalline silicon solar cells.

Another significant patent is the preparation method for the patternization of metal electrodes in silicon solar cells. This invention describes a process where an amorphous silicon layer is disposed on a silicon substrate. Laser light is projected onto the amorphous silicon layer for patternization, transforming it into polysilicon with high optical conductivity. This innovative approach allows for accurate formation of metal electrodes without the need for external voltage, as the plating reaction is induced directly by illumination.
