  • Publication number: 20200168600
    Abstract: The invention aims for a polarisation circuit of a power component comprising a capacitive dividing bridge and a resistive dividing bridge formed on the same substrate as the component. An additional electrode 1? in the front face 100 of the substrate makes it possible to adjust one of the capacitance values of the capacitive dividing bridge according to the other of the capacitance values coming from one of the electrodes of the power component. The sizing of this additional electrode furthermore makes it possible to obtain a leakage resistance contributing to the resistive dividing bridge. Alternatively, two additional resistances R, R? formed in the front face of the substrate making it possible to obtain the resistive dividing bridge independently of the capacitive dividing bridge.

    Abstract: The invention relates to a photovoltaic cell with silicon heterojunction comprising a doped crystalline silicon substrate, in which: —a first face of the substrate is successively covered with a passivation layer, an amorphous or p or p+ doped microcrystalline silicon layer and a layer of a transparent conducting material, —the second face of the substrate is successively covered with an amorphous or n or n+ doped microcrystalline silicon layer and a layer of a transparent conducting material. Between the substrate and the amorphous or n or n+ doped microcrystalline silicon layer, the cell comprises a layer of a crystalline semi-conducting material selected from gallium nitride or indium gallium nitride and having a conduction band that is sensitively aligned with the conduction band of the silicon and a band gap greater than that of silicon, in such a way as to promote an electron current while limiting a hole current in the substrate towards the amorphous or n or n+ doped microcrystalline silicon layer.

    Abstract: An electronic device includes a heat source, a heat-absorbing cold point, a thermally insulating material for insulating the heat source from the cold point with a conductivity at a use-temperature of electronic device, that is below a thermal-conductivity threshold, and a thermal bridge having first and second ends connected by pads to the heat source and the cold point, and a thermal switch. The thermal bridge extends between the two ends and switches reversibly between conductive and non-conductive states. It includes material of variable thermal conductivity capable of switching over, in response to an addition of energy, between a conductive phase and a resistive phase, and a control module for causing the thermal switch to switch between the conductive state and the resistive state.
