Meeting the Growing Needs of the Chinese Market

Establishment of a Manufacturing
Base in China for High-Performance Solar Cell Conductive Paste Business

To date, Kyoto Elex has developed and manufactured various high-performance conductive pastes for electronic parts and solar cells.
Of these pastes, our conductive paste for HJT solar cells has earned high praise from a wide range of customers. We are dedicated to developing and providing this paste to various solar cell manufacturers in the United States, Europe, China, and East Asia.
To do so, we are planning to establish a manufacturing base in China in response to the rapid growth of our Chinese customer base.
We expect high-performance conductive pastes manufactured at this base to be available next year and look forward to sharing them with the world.
