Bert Thin Films, LLC has been awarded a $1M grant from the US Department of Energy Solar Energy Technologies Office. The project goal is to further de-risk the copper based paste technology developed by the team for the photovoltaic industry. 

“Investing in clean energy technologies like solar not only helps us combat climate change, it strengthens our energy and manufacturing sectors, creating good jobs while building the economy of the future. I’m so thrilled that Louisville’s own Bert Thin Films is leading the way in this industry, working to reduce costs and expand access to an inexhaustible clean energy source. I congratulate Thad and Ruvini on earning this highly sought-after Department of Energy funding to continue their great work here in Louisville,” said U.S. Congressman John Yarmuth (KY-3).

PV Magazine states:  The U.S. Department of Energy has awarded $1 million to a company making a splash in solar manufacturing materials, providing funds to Bert Thin Films for their new copper paste material that is designed to replace expensive silver components in solar panels. 


The Louisville, Kentucky-based company has been gathering steam as they secured $1 million in funding in early 2019, according to the Securities and Exchange Commission. 

Bert Thin Films said their paste, named CuBert, maintains the durability of silver paste, and can be seamlessly integrated into existing manufacturing processes and equipment in use today by solar panel makers. 

Bert Thin Films was awarded $500k to continue the development of the copper based pastes as being developed as part of the National Science Foundation SBIR program. The work will extend the technology development which includes making changes at the cell level to keep up with the rapidly changing solar cell architectures being introduced by the industry.


Bert Thin Films has closed on a $1M seed funding round led by Queen City Angels.  QCA investments "are usually companies throughout the state of Ohio that focus on technology such as cloud-based solutions, solar, manufacturing, life sciences and biotech. The first company to receive an investment from the fund was Bert Thin Films out of Louisville, Ky."
