Solar cells have been one of the driving renewable energy sources of the past decade. Efficiency has increased and manufacturing cost has dropped. However, it only accounts for less than 2% of today energy production. To be economically competitive with conventional energy sources further improvement are necessary. One of the current limiting factors in reducing the production price further is the need of silver busbars. Current fabrication techniques are not able to fabricate copper busbars without destroying the PV material.
Development of high quality of nano- and advanced materials can improve light absorption, ensure a more efficient conversion of the energy of light to electricity and improve energy transport and storage.
Around the world on solar power
In 2015, the solar powered airplane by the Solar Impulse Foundation started it's journey around the world. Bringing a clear message: everybody could use the same technologies on the ground to halve our world’s energy consumption, save natural resources and improve our quality of life. Because we will need to greatly improve the efficiency of clean technologies, they started the World Alliance Network, gathering efficient solutions from members globally. VSPARTICLE is a member of the World Alliance as an innovator, bringing novel nanostructured materials to CleanTech.
VSPARTICLE enables room temperature printing of nanostructured copper that can be post processed at low temperature. This means that copper busbars can be fabricated without damaging the PV material.
