The use of titanium dioxide particles coated by an organic coating for increasing the hydrolysis resistance of an oriented polyester film, particularly wherein the organic coating does not comprise or is not derived from a silane, and particularly wherein the organic coating is selected from an organophosphorus compound and a polymeric organic coating; and oriented polyester films comprising such titanium dioxide particles coated by an organic coating; and photovoltaic cells comprising such films.

Provided is a resin composition used for forming a laminated glass interlayer film or a solar cell encapsulant, the resin composition including an ionomer (A) of an ethylene-unsaturated carboxylic acid-based copolymer, wherein metal ions constituting the ionomer (A) of the ethylene-unsaturated carboxylic acid-based copolymer includes two or more kinds of polyvalent metal ions.

A method is provided that integrates an autonomous energy harvesting capacity in a mobile device in an aesthetically neutral manner. A unique set of structural features combine to implement a hidden energy harvesting system on a surface of the mobile device body structure or casing to provide electrical power to the mobile device, and/or to individually electrically-powered components in the mobile device. Color-matched, image-matched and/or texture-matched optical layers are formed over energy harvesting components, including photovoltaic energy collecting components. Optical layers are tuned to scatter selectable wavelengths of electromagnetic energy back in an incident direction while allowing remaining wavelengths of electromagnetic energy to pass through the layers to the energy collecting components below. The layers appear opaque when observed from a light incident side, while allowing at least 50%, and as much as 80+%, of the energy impinging on the energy or incident side to pass through the layer.
