About Tandem PV
Tandem PV is a solar energy company developing perovskite-based solar panels. The company's proprietary technology involves stacking thin-film perovskite on top of conventional silicon solar cells, a design referred to as tandem perovskite panels. This approach is engineered to increase the power output of traditional solar modules, with the company reporting panel efficiencies of 28%.
The business model is centered on the manufacturing and sale of these high-efficiency solar panels. By increasing the energy output per panel, the company aims to reduce the overall cost of solar energy, making it a more competitive energy source. The company is currently in the process of building out its manufacturing infrastructure to scale up production and accelerate the commercialization of its products.
Based in Silicon Valley, Tandem PV was founded in 2016 and has secured significant funding to support its growth and manufacturing expansion. The company's primary market is the solar energy sector, with a goal of re-establishing U.S. leadership in solar manufacturing and contributing to the transition to a net-zero economy.
