Patent number: 9178097Abstract: Methods are described for forming CIGS absorber layers in TFPV devices with graded compositions and graded band gaps. Methods are described for utilizing Al to increase the band gap at the front surface of the absorber layer. Methods are described for forming a Cu—In—Ga layer followed by partial or full selenization. This results in a higher Ga concentration at the back interface. The substrate is then exposed to an aluminum CVD precursor while the substrate is still in the selenization equipment to deposit a thin Al layer. The substrate is then exposed to a Se source to fully convert the absorber layer. This results in a higher Al concentration at the front of the absorber.Type: GrantFiled: February 13, 2014Date of Patent: November 3, 2015Assignee: Intermolecular, Inc.Inventors: Haifan Liang, Jeroen Van Duren

Patent number: 9112095Abstract: In some embodiments, Cu—In—Ga precursor films are deposited by co-sputtering from multiple targets. Specifically, the co-sputtering method is used to form layers that include In. The co-sputtering reduces the tendency for the In component to agglomerate and results in smoother, more uniform films. In some embodiments, the Ga concentration in one or more target(s) is between about 25 atomic % and about 66 atomic %. The deposition may be performed in a batch or in-line deposition system. If an in-line deposition system is used, the movement of the substrates through the system may be continuous or may follow a “stop and soak” method of substrate transport.Type: GrantFiled: December 14, 2012Date of Patent: August 18, 2015Assignee: Intermolecular, Inc.Inventors: Teresa B. Sapirman, Philip A. Kraus, Sang M. Lee, Haifan Liang, Jeroen Van Duren

Patent number: 9109121Abstract: Methods and compositions for forming porous low refractive index coatings on substrates are provided. The method comprises coating a substrate with a sol-formulation comprising silica based nanoparticles and an alkyltrialkoxysilane based binder. Use of the alkyltrialkoxysilane based binder results in a porous low refractive index coating having bimodal pore distribution including mesopores formed from particle packing and micropores formed from the burning off of organics including the alkyl chain covalently bonded to the silicon. The mass ratio of binder to particles may vary from 0.1 to 20. Porous coatings formed according to the embodiments described herein demonstrate good optical properties (e.g. a low refractive index) while maintaining good mechanical durability due to the presence of a high amount of binder and a close pore structure.Type: GrantFiled: October 13, 2011Date of Patent: August 18, 2015Assignees: Intermolecular, Inc., Guardian Industries CorporationInventors: Nikhil D.
