Film-based photovoltaic modules employ monolithic interconnects to minimize resistance loss and enhance module voltage via series connection. Conventional interconnect construction occurs sequentially, with a scribing step following deposition of the bottom electrode, a second scribe after deposition of absorber and intermediate layers, and a third following deposition of the top electrode. This method produces interconnect widths of about 300 µm, and the area comprised by interconnects within a module (generally about 3 %) does not contribute to power generation. The present work reports on an increasingly popular strategy capable of reducing the interconnect width to less than 100 µm: printing interconnects. Cost modeling projects a savings of about $0.02/watt for CdTe module production through the use of printed interconnects, with savings coming from both reduced capital expense and increased module power output. Printed interconnect demonstrations with copper-indium-gallium-diselenide and cadmiumtelluride solar cells show successful voltage addition and miniaturization down to 250 µm. Material selection guidelines and considerations for commercialization are discussed.

“…Li and coworkers applied one‐step method to prepare a UV‐curable polysiloxane methacrylate (PSMA). And the UV‐cured PSMA film was obtained using 2‐hydroxy‐2‐methyl‐1‐phenyl‐propan‐1‐one as a photoinitiator, confirming good thermal stability, excellent transparency and satisfactory tensile strength . A novel water‐soluble hyperbranched photosensitive polysiloxane urethane acrylate (WHBPSUA) was reported and low‐molecular‐weight photoinitiator (2‐hydroxyl‐2‐methyl‐1‐phenylpropane‐1‐one) was also selected.…”

In this contribution, three polymerizable benzophenone photoinitiators containing maleimide group including 4‐maleimidebenzophenone (MBP), 4‐chlorine‐4′‐maleimide benzophenone (CMBP), and 4‐maleimide‐4′‐[(4‐maleimide)thiophenyl]benzophenone (MMTBP) were designed and synthesized to enhance the polymerization degree of photosensitive polysiloxane containing methacryloxy active groups (MAPSO). The polymerization behaviors of the MAPSO cured by different photoinitiators were investigated using Fourier transform infrared (FTIR). It was noted that the MAPSO initiated by MMTBP showed a high carbon–carbon double bond conversion above 80% because of the existence of thiophenyl group which could generate more radicals from the photolysis reaction at the CS bond. In addition, the thermal stability of the UV‐cured MAPSO were studied by thermogravimetric analysis (TGA), the result showed that the initial 5% mass loss (T5%) and residual weight percent at 800 °C in nitrogen of the UV‐cured MAPSO initiated by MMTBP systems was 200 °C and 33.8%. Thus, this work provides a new perspective and efficient strategy to improve the polymerization degree of UV‐curable polysiloxanes with carbon–carbon double bonds. © 2017 Wiley Periodicals, Inc. J.

“…Among them, good interfacial adhesion is a critical prerequisite for the mechanical enhancement in fiber/polymer composites, because it ensures an effective load transfer from basal resin to fiber . Therefore, various methods have been developed in the past few decades to obtain interfacial enhancement, such as to increase the specific surface area of fibers, improve the chemical activity of fiber surfaces and match the compatibility between basal resin and fiber . Especially, it has been proposed, in recent years, that interfacial crystallization might be a promising approach for enhancing polymer/fiber interfacial interactions in composite systems composed of semicrystalline polymer and fibrous‐like filler .…”

Bioresource natural sisal fiber (SF) was used to prepare single fiber-reinforced isotactic polypropylene (iPP) composites. Three kinds of interfacial crystalline morphologies, spherulites, medium nuclei density transcrystallinity (MD-TC) and high nuclei density transcrystallinity (HD-TC), were obtained in the single fiber-reinforced composites by implementing quiescent or dynamic shear-enhanced crystallization and by modulating the compatibility interaction between SF and iPP. The development of interfacial shear strength (IFSS) during the interfacial crystallization process was demonstrated for the first time using a combination of single-fiber fragmentation testing and optical microscope observation. A close correlation between IFSS and morphological characteristics of interfacial crystallization was well elucidated. The increases in IFSS were very different for spherulitic, MD-TC and HD-TC morphologies. The highest IFSS obtained was 28 MPa, after the formation of HD-TC, which was about 62% of the tensile strength of neat iPP (45 MPa). These results offer powerful and direct evidence that interfacial crystallization could play an important role in the enhancement of interfacial adhesion of real SF/iPP composites.
