摘要： Organic photovoltaic devices with compound charge transport layers are described herein. One such device includes a substrate, a first electrode coupled to the substrate, a second electrode disposed above the first electrode, and photoactive layers disposed between the first electrode and the second electrode. The device further includes a compound charge transport layer disposed between the photoactive layers and either the first electrode or the second electrode. The compound charge transport layer includes a charge transport layer and a metal-oxide interlayer disposed between the charge transport layer and the photoactive layers. The charge transport layer may be a hole transport layer or an electron transport layer.

摘要： Photoactive compounds are disclosed. The disclosed photoactive compounds include metal complexes with dipyrromethene-based ligands, which can be substituted with a variety of different side chains or groups or can include various fused ring configurations, such as including aromatic or heteroaromatic groups. The metal complexes may include two dipyrromethene-based ligands, which can be the same or different. The photoactive compounds can be used as photoactive materials in organic photovoltaic devices, such as visibly transparent or opaque photovoltaic devices.

摘要： Visibly transparent photovoltaic devices having bulk heterojunctions (BHJ) are disclosed. Such devices are transparent to visible light but absorb near-infrared light and/or ultraviolet light. The photovoltaic devices may include bottom and top visibly transparent electrodes, as well as multiple stacked BHJ active layers that have complementary absorption characteristics. For example, a first BHJ active layer may have an absorption spectrum that is complementary to an absorption spectrum of a second BHJ active layer.

摘要： Photoactive compounds are disclosed. The disclosed compounds can exhibit molecular structural elements tending to increase the evaporability or volatility of the compounds, such as by including geometric core disruption by use of conformationally restricted side groups instead of freely rotatable side groups or use of indandione moieties instead of dicyanomethyleneindanone moieties. The disclosed photoactive compounds include those with an imine-bridging linking moiety, which can shift the optical properties to a more red-shifted absorbance as compared to compounds with an alkene-bridging linking moiety. The disclosed photoactive compounds can be used in organic photovoltaic devices, such as visibly transparent or opaque photovoltaic devices.

摘要： Disclosed herein are visibly transparent photovoltaic devices, such as color-neutral visibly transparent photovoltaic devices. A color-neutral visibly transparent photovoltaic device includes a visibly transparent substrate and a first visibly transparent electrode coupled to the visibly transparent substrate. The device also includes a second visibly transparent electrode and a visibly transparent photoactive layer between the first visibly transparent electrode and the second visibly transparent electrode. The visibly transparent photoactive layer is configured to convert at least one of NIR light or UV light into photocurrent and is characterized by an absorption spectrum with a peak in the NIR or UV spectrum. The device further includes a visibly absorbing material characterized by a second absorption spectrum with a second peak in the visible spectrum, where the second absorption spectrum is complementary to the absorption spectrum.

摘要： This application relates generally to the field of photovoltaic materials and devices, and, more particularly, to insulated glass units combining a visibly transparent (or semitransparent) photovoltaic structure and a low emissivity structure to provide a color neutral insulated glass unit while also improving the solar heat gain coefficient as compared to the use of the visibly transparent (or semitransparent) photovoltaic structure alone. In some embodiments, the photovoltaic and low emissivity structures are formed on separate lites (i.e., pieces of glass) and combined during fabrication of the insulated glass unit.
