Solar power needs a more ambitious cost target

Nature Energy volume 1, Article number: 16036 (2016) Cite this article

Subjects

Solar power is increasingly economical, but its value to the grid decreases as its penetration grows, and existing technologies may not remain competitive. We propose a mid-century cost target of US$0.25 per W and encourage the industry to invest in new technologies and deployment models to meet it.
