Founded2002

Nanosolar, Inc. was a U.S.-based company founded in 2002 that specialized in the development and manufacturing of thin-film solar cells using a proprietary printing process for Copper Indium Gallium Selenide (CIGS) technology. The company aimed to significantly reduce the cost of solar energy by leveraging nanoparticle inks and high-throughput roll-to-roll manufacturing. Despite raising substantial venture capital and achieving some technological milestones, Nanosolar faced intense market competition, manufacturing challenges, and financial difficulties, ultimately leading to its cessation of operations around 2013. Its technology and assets were subsequently acquired by other entities. Nanosolar represented a significant effort in the quest for cheaper and more efficient solar power.

Where Is Nanosolar's Headquarters?
