Film Adhesion of Flexible Electronics Influenced by Interlayers

Compression-induced delamination is a technique that uses the buckling dimensions to evaluate the interfacial adhesion of materials on flexible substrates quantitatively. This study shows that spontaneous buckles are formed in gold (Au) films, which are deposited without an interlayer. Conversely, external loading is required to delaminate the Au film with the tantalum (Ta) adhesion layer indicating higher adhesion energy.

Spray-Coated Polymer Solar Cells Based on Low-Band-Gap Donors Processed with ortho-Xylene

A low-band-gap material blend was dissolved in the non-chlorinated solvent ortho-xylene for both spin-coating and spray-coating of active layers for polymer solar cells. The results open the way to the use of spray-coating to scale up the deposition of active layers.
