Flexible CIGS solar technology allows for lightweight, flexible solar modules that overcome limitations of traditional rigid glass modules. Ascent Solar produces flexible CIGS modules using a roll-to-roll manufacturing process and monolithic integration techniques. This allows their modules to be highly efficient, lightweight and flexible, making them well-suited for applications such as consumer products, transportation, defense, and building integration. Their technology and products target significant market opportunities in areas like portable electronics charging, electric vehicles, and building-integrated photovoltaics.
