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.

Compound charge transport layer for organic photovoltaic devices

Photoactive compounds are disclosed. The disclosed compounds can exhibit molecular structural elements tending to increase the evaporability 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.

Photoactive compounds for vapor deposited organic photovoltaic devices

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.

Metal coordinated photoactive compounds for transparent photovoltaic devices

Photovoltaic devices having photoactive layers coupled to buffer layers are disclosed. Such devices may be transparent to visible light but absorb near-infrared light and/or ultraviolet light. The photovoltaic devices may include a p-phenylene layer that acts as a buffer layer. The photovoltaic devices may include one or more photoactive layers. The one or more photoactive layers may include a single planar heterojunction, a single bulk heterojunction (BHJ), or multiple stacked BHJs that have complementary absorption characteristics, among other possibilities.

An extendible extension handle that can be used with wrenches, ratchets, tire iron and such to permit the user to increase the leverage applied to the tool. The inner handle assembly is the base to engage the handle at one end and the tools at the opposite end. The tool end of the inner handle assembly has first and second openings in it's upper base to engage the handle portion and closed end portion of wrenches and an opening on bottom base to engage opening end wrenches. The inner handle assembly being tubular in structure allows for ratchets, tire iron and such to easily be inserted into the base. It fits around the inner handle assembly tool end and has a opening down it's shaft to engage the wrench. Once the wrench has been engage the stabilizer can be a align to a locking position which will allow the user to adjust the tension on the stabilizer clamping mechanism. The stabilizer assembly mobility is limited to a circular rotation by fixed bushings attached to the inner handle assembly. The outer handle assembly is telescoped with a L shape groove down portion of it's length and a latching mechanism for various adjustments.
