Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A rectangular hand-mounted connector with d-shaped geometrical bay areas for providing easy mounting or dismounting compatibility in a commercial application without the use of any special tool is disclosed. The connector system uses a plurality of hooks located at the top and bottom of the receptacle shell to mate with a plurality of draw latches or bail latches at the top and bottom of the plug shell. In an alternative embodiment, a vertical clamping latch system is used to engage the receptacle and plug assembly. A polarization key in the receptacle shell provides latch tension when it is mated with its mating part from the plug shell. Strain reliefs may be connected to the receptacle or plug shell and may further having a plurality of ground studs for grounding the electrical contacts.

Abstract: An electromagnetic interference (EMI) and environmentally protected cap assembly for electrical connectors, for use when the mating connector is not in place, includes a hollow outer housing having a large diameter rear end and a smaller diameter front end having inwardly directed teeth for locking behind the outwardly extending lugs on the cylindrical form of the connector. An inner body member which is rotatable with respect to the housing, is spring biased by a plurality of wave washers toward the front of the outer housing. The inner housing has recesses which mate with the lugs on the connector to prevent relative rotation of these two parts, and detenting means are provided between the housing and the inner body member for locking the cap assembly onto the connector when the outer housing is assembled to the connector and rotated.

Abstract: A quantity of circuit chips are slidingly received in end to end relation in an elongated receptacle or "stick". The required number of such sticks are located in parallel groups at each side of a substrate mounted on an adjustable support. A pair of vacuum heads reciprocate along a path transversely of the substrate a fixed amount from a first extreme with the vacuum head located immediately over the endmost chip in a stick, to a second extreme which is a constant distance from the first position and lying over the substrate. The substrate is positioned to the proper x-y location such that when the transfer mechanism moves a chip to the position over the substrate, it will be properly located at the correct part of the substrate circuit. The sticks are indexable as needed to a position presenting the endmost chip of the selected stick underneath the outer extreme of the movement of the vacuum head. Control apparatus positions the substrate in any desired series of x-y locations.
