Toshiba Mitsubishi-Electric Industrial Systems Corporation will be delivering its Busbar Bonding Machine to the world’s largest CIGS plant with 300 MW capacity in Phase 1 with a production capacity of 1.5GW.

Toshiba Mitsubishi-Electric Industrial Systems Corporation received an order for three units of its Busbar Bonding Machine (TMBBM) for Triumph PV Materials Ltd. The products will be delivered to the world’s largest CIGS plant (300MW in Phase 1 with a production capacity of 1.5GW) constructed by Triumph PV Materials Ltd. in Bengbu City, An Hui Sheng, China. The TMBBM units are scheduled to commence operation in October 2017 and will additionally be installed at a new plant constructed by Triumph PV Materials Ltd. in Jiangyin, Jiangsu, China.

TMBBM applies TMEIC’s proprietary ultrasonic welding technology to directly bond electrodes such as aluminum ribbon to solar cells’ glass substrates. While it has been common to use welding materials such as solder and paste, this machine realizes welding without these materials, thereby reducing the manufacturing cost of solar cells’ wiring process by approximately 50%.

TMEIC, together with Mitsubishi Diamond Industrial Co., Ltd. (hereinafter, “MDI”), consistently handles the sequence of processes from patterning to welding electrodes, which in turn ensures the quality of solar cells, improves the yield ratio and builds a sustainable system that will realize vertical start-up at the time of constructing a production line. MDI and TMEIC were selected exclusively as a Japanese supplier for the current project. Going forward, in order to make inroads into other areas such as perovskite-based solar cells^*5, for which there are high expectations as next-generation solar cells in addition to CIGS, TMEIC will continue cooperating with MDI to actively make proposals to solar cell manufacturers in respective countries worldwide in an effort to expand sales.
