    摘要： A semiconductor module comprises a string made up of a plurality of cells or strips arranged in series. A front surface of at least one cell or strip, has a polarity opposite to that of the front surface of another cell or strip in the string. In some embodiments the strips may comprise photovoltaic devices of different structures, for example Heterojunction (HJT) and Tunnel Oxide Passivated Contact (TOPCon). According to certain embodiments, one or more cells or strips of the string may be arranged in an overlapping shingled configuration, such that a front surface of the overlapped strip exhibits the appropriate polarity. For particular embodiments, one or more cells or strips may be adjacent in the string, such that a cell or strip has a front or back surface of polarity appropriate to connect with the adjacent cell or strip (e.g., using a ribbon located on a same surface).

    摘要： Deposition processes are disclosed herein for depositing thin films comprising a dielectric transition metal compound phase and a conductive or semiconducting transition metal compound phase on a substrate in a reaction space. Deposition processes can include a plurality of super-cycles. Each super-cycle may include a dielectric transition metal compound sub-cycle and a reducing sub-cycle. The dielectric transition metal compound sub-cycle may include contacting the substrate with a dielectric transition metal compound. The reducing sub-cycle may include alternately and sequentially contacting the substrate with a reducing agent and a nitrogen reactant. The thin film may comprise a dielectric transition metal compound phase embedded in a conductive or semiconducting transition metal compound phase.

    摘要： Disclosed is a quantum dot based solar cell device which includes a substrate, a light harvesting structure sandwiched between electrically conducing layers, with at least one electrically conducting layer being substantially transparent with the light harvesting structure being located on the substrate. The light harvesting structure includes a layer of semiconducting quantum dots, with this layer of semiconducting quantum dots including at least two distinct sets of semiconducting quantum dots which are homogenously mixed. One of the two distinct sets of semiconducting quantum dots has a first bandgap and the at least one other distinct set of semiconducting quantum dots has a second bandgap different from the first bandgap. Both sets of semiconducting quantum dots are passivated with any one or combination of halides and pseudo-halides. Upon illumination, the quantum dot solar cell device exhibits a photovoltage that is intermediate between a photovoltage that would generated separately if the solar cell device had only the first set of quantum dots and a photovoltage that would be generated separately if the solar cell device had only the second set of quantum dots.
