Methods for increasing the degree of curing and/or reducing the volatile photoinitiator concentration in cured polymeric film, and particularly in cured polymeric films in a multilayered thin film encapsulation stack are provided. Also provided are highly crosslinked and/or low-outgassing thin polymeric films and encapsulation stacks made using the methods.

Two-step process for forming cured polymeric films for electronic device encapsulation

The present invention is directed to a paste composition comprising Al and Sn dispersed in an organic medium and to paste compositions that provide a solderable electrode. The present invention is further directed to an electrode formed from the paste composition and a semiconductor device and, in particular, a solar cell comprising such an electrode. The paste compositions that provide a solderable electrode are particularly useful for forming a solar cell back side solderable electrode.

The nanoparticle fluid further includes a set of capping agent molecules, wherein at least some capping agent molecules of the set of capping agent molecules are attached to the set of nanoparticles.

Methods for forming a dual-doped emitter on a silicon substrate with a sub-critical shear thinning nanoparticle fluid

Poly-siloxane material may be used to form an insulating structure in an organic light-emitting device (OLED). In addition to the insulating structure, an OLED may have an electro-luminescent organic layer separated into light-emitting elements, e.g., display pixels, arranged between electrode layers. A voltage applied across the electrode layers causes the device to emit light. One type of insulating structure may be a bank structure formed from a thin sheet of poly-siloxane with apertures corresponding to the display pixels. Pixels may be formed with the deposit of one or more layers of organic material into the apertures. Another type of-insulating structure may be one or more insulating strips, which may separate an electrode layer into electrode strips during construction and/or insulate electrode strips while the OLED is in operation.
