…I don’t believe that quantum dot solar is the solution because I’m in the quantum dot solar business, but rather,
I’m in the quantum dot solar business because I believe it is the only viable solution to the world’s future energy needs. If we are going to solve the global warming issue, we will need to make all of you believers, too.

Business Objective

Solterra’s objective is to become the first quantum dot solar cell (QDSC) manufacturer to be able to offer a solar electricity solution that competes below the retail price of electricity worldwide. Solterra intends to acquire a significant amount of solar photovoltaic market share by introducing a new generation of solar cells built on industry-leading technologies that are ready to emerge from the R&D realm and begin full-scale production by commercializing a high volume, extremely competitive cost-per-watt, quantum dot based third-generation photovoltaic solar cell.

Quantum Materials Corp, the parent company of Solterra, has the capability to scale production of quantum dot material necessary to power Solterra’s solar cells. Solterra has proprietary technology to mass-produce quantum dot solar cells using roll-to-roll printing technology at hundreds of meters per minute. The manufacture of thin-film quantum dot solar cells introduces a cost-effective disruptive technology that will accelerate the conversion from a fossil fuel dependent energy infrastructure to one based on renewable, carbon-neutral, solar energy sources. To accomplish this, Solterra Renewable Technologies has the goal of globally marketing our low-CAPEX QDSC factories, and internally scaling-up each factory by increasing quantum dot conversion efficiency and speed of production for a continually improved product and increasing quantities.

QD Solar Cells

Quantum Dot Solar Cells, unlike conventional silicon solar cells, convert the entire spectrum from ultraviolet to visible light to infrared into electricity and have a maximum potential quantum efficiency of 65% compared to half that amount using current silicon-based technology
