Abstract
This invention relates to processes for materials using a range of compounds, polymeric compounds, and compositions used to prepare semiconductor and optoelectronic materials and devices including thin film and band gap materials for photovoltaic applications including devices and systems for energy conversion and solar cells. In particular, this invention relates to CIGS, CIS or CGS materials made by a process of providing one or more polymeric precursor compounds or inks thereof, providing a substrate, depositing the compounds or inks onto the substrate; and heating the substrate, thereby producing a material.
Claims20
A material made by a process comprising,
- (a) providing one or more CIGS, CIS or CGS polymeric precursor compounds or inks thereof;
- (b) providing a substrate;
- (c) depositing the compounds or inks onto the substrate;
- and
- (d) heating the substrate at a temperature of from about 20° C. to about 650° C. in an inert atmosphere, thereby producing a material.
