Abstract: Embodiments of the present invention are directed to processes for making solar cells by simultaneously co-firing metal layers disposed both on a first and a second surface of a bifacial solar cell substrate. Embodiments of the invention may also provide a method forming a solar cell structure that utilize a reduced amount of a silver paste on a front surface of the solar cell substrate and a patterned aluminum metallization paste on a rear surface of the solar cell substrate to form a rear surface contact structure. Embodiments can be used to form passivated emitter and rear cells (PERC), passivated emitter rear locally diffused solar cells (PERL), passivated emitter, rear totally-diffused (PERT), “iPERC,” Crystalline Reduced-cost Aluminum Fire-Through (CRAFT), pCRAFT, nCRAFT or other high efficiency cell concepts.

Abstract: An adaptive backlight module and a method and system for producing an adaptive backlight module are described herein. The method of producing an adaptive backlight module includes: forming at least one enhancement film on a first substrate, forming a polarizer on the enhancement film, forming a diffuser by forming a liquid crystal layer between a first electrode on the first substrate and a second electrode on a second substrate, and connecting the diffuser to a light source.
