Abstract

Conventional patterning processes for series connection of silicon thin film solar cells are composed of laser scribing processes, such as pattering of front electrode (P1), patterning of silicon thin films (P2) and patterning of silicon thin films and back electrode (P3). However, we have proposed a new series connection scheme of silicon thin film solar cells using direct inkjet patterning technology. The combination of laser scribing and inkjet printing technologies can realize the series connected cell structure. After the deposition of silicon thin films without P1 process, both front electrode and silicon thin films are patterned first by ultra violet (UV) laser scribing with the wavelength of 352 nm. Then, to prevent the shunting between front and back electrodes, spacers were formed on the sidewalls of laser scribed lines by inkjet printing. The series connected cells were fabricated by the following deposition of back electrode and P3 laser scribing process. In this research, we have developed the spacer formation process using the resin based dielectric ink. Also, we have fabricated and characterized the amorphous silicon (a-Si) thin film solar modules with proposed structure.
