    Abstract: Passivated contact structures and fabrication methods for back contact back junction solar cells are provided. According to one example embodiment, a back contact back junction photovoltaic solar cell is described that has a semiconductor light absorbing layer having a front side and a backside having base regions and emitter regions. A passivating dielectric insulating layer is on the base and emitter regions. A first electrically conductive contact contacts the passivating dielectric insulating layer together having a work function suitable for selective collection of electrons that closely matches a conduction band of the light absorbing layer. A second electrically conductive contact contacts the passivating dielectric insulating layer together having a work function suitable for selective collection of electrons that closely matches a valence band of the light absorbing layer.

  • Patent number: 9490610
    Abstract: An electrical isolation apparatus to automatically interrupt main power in advance of its junction to the main electrical panel whenever the main disconnect switch is turned off. A method for retrofitting an existing electrical panel enclosure with an electrical isolation box (EIB) is also disclosed, along with a retrofit kit. The electrical isolation apparatus includes an auxiliary relay resident in the main electrical panel enclosure and actuated by said main disconnect switch. The electrical isolation apparatus also includes the EIB in a second ride-on enclosure attached to the main panel enclosure. The EIB encloses a power contactor with at least one power contactor switch (three for three-phase). The control input of the power contactor is connected through both enclosures to the auxiliary relay resident in the main enclosure for controlling the power contactor. Indicator lights, a voltage monitor, and a reset/test switch panel-mounted on the EIB enclosure are also disclosed for status display.

  • Publication number: 20070082641
    Abstract: A single chip receiver is disclosed herein. The chip only requires an external antenna for operation. A decoder is formed on chip for performing logical operations on demodulated digital data. A baseband filter is controlled by external control signals to have one of a plurality of discrete frequency response bandwidths depending on the type of signal to be received. To compensate for process variations in the implementation of the IC, bias currents setting the operating conditions for various amplifiers and other components in the system are adjusted based on frequency control signals in a PLL circuit in the local oscillator. Since the magnitude of the control signal reflects the process variations, the bias currents are adjusted based on the control signal to offset these variations in other portions of the receiver.
