摘要： Illustrative embodiments of the invention generally relate to photovoltaics and solar energy harvesting devices and, particularly, to those that are transparent or semi-transparent, allowing sufficient visible light through them to allow visualization of objects through them, and more particularly, to those that supplement their primary near ultraviolet light absorption with secondary and/or tertiary absorptions of narrow bands of visible light while maintaining their transparency. Various embodiments of the invention relate to single solar materials with both primary ultraviolet absorption and secondary, narrow-band visible absorption, while some embodiments of the invention utilize mixtures of one or more materials to realize a primary ultraviolet absorption of light with secondary, or even tertiary, narrow bands of visible light absorption. Means of manufacturing such photovoltaics and solar energy harvesting devices will also be disclosed as well as the applications and uses thereof.

摘要： A display apparatus with high resolution or high definition is provided. The display apparatus includes a first light-emitting device, a second light-emitting device, a first insulating layer, a first coloring layer, and a second coloring layer. The first light-emitting device includes a first pixel electrode, a first EL layer, and a common electrode that are stacked in this order. The second light-emitting device includes a second pixel electrode, a second EL layer, and the common electrode that are stacked in this order. The first coloring layer overlaps with the first light-emitting device. The second coloring layer transmitting light of a color different from a color of light transmitted by the first coloring layer overlaps with the second light-emitting device. The first EL layer and the second EL layer have the same structure and are separated from each other. An end portion of the first EL layer is positioned over the first pixel electrode. An end portion of the second EL layer is positioned over the second pixel electrode. The first insulating layer covers side surfaces of the first pixel electrode, the second pixel electrode, the first EL layer, and the second EL layer. The common electrode is positioned over the first insulating layer.
