Abstract: Provided is an apparatus for manufacturing a composite material consisting of a flexible substrate and a multilayer nanostructured PV-active film supported by the substrate. The apparatus comprises a sealable chamber, the cylindrical inner wall of which is used as a support for a flexible substrate. The chamber contains a rotating crucible having a recess in its center and flat margins. The apparatus is provided with a power laser capable of generating an annular beam focused on the aforementioned flat surface. In operation, a nanoparticle-containing colloidal solution is supplied to the crucible. During rotation, the solution moves to the flat margins where it forms a thin layer that is evaporated by means of the annular laser beam. As the solution evaporates, the nanoparticles, which remain on the surface, fly out by inertia from the edges of the crucible to the flexible substrate. The deposition process can be controlled so that the deposited layers form a PV-active film.

Abstract: Proposed is the backside silicon photovoltaic cell and method for forming backside selective emitters, backside doped base contact regions, backside field-induced emitters, FSF-regions, and contacts to the functional regions of a backside solar cell by essentially electrical means and without conventional thermal diffusion and masking processes. The process includes forming conductive layers on both sides of an intermediate device structure, performing Joule heating by passing electrical current through the backside conductive layers thus forming the selective emitters, the base contact regions, and contacts to the functional regions. The obtained structure is then subjected to pulse electrical treatment by applying a voltage pulse or pulses between the front and back conductive layers to form the field-induced emitter and the field-induced FSF. After the conductive layers are removed, a final solar cell is obtained. The proposed method can significantly simplify manufacturing, reduce cost, and increase throughput in the field of semiconductor fabrication.

Abstract: Proposed is a composite photovoltaic device with parabolic collector and different solar cells, wherein the high photoelectric conversion efficiency is achieved along with significant material cost reduction. The device comprises two or three solar cells formed on opposite sides of a transparent substrate, and a parabolic collector attached to the back side of the substrate. First thin film solar cell formed on the front side receives and converts to electricity a short-wavelength portion of the incoming Sun radiation, and transmits the long-wavelength portion. A second solar cell receives and converts to electricity a concentrated long-wavelength portion of the Sun radiation, which is re-directed toward a focal point by the parabolic collector. In one embodiment a third solar cell is included for converting an IR portion of the radiation. Thus, each solar cell utilizes a favorable part of the Sun spectrum, which allows for an enhancement of photoelectric efficiency and significant material cost reduction.

Abstract: The invention provides a method of manufacturing a monolithic thin-film photovoltaic cell or module with enhanced output voltage as high as 100 V or higher in a single microelectronic process without connecting in series a plurality of premanufactured solar cells. The method consists of forming a plurality of adjacent individual TSCs arranged on a common transparent substrate in the longitudinal direction of the substrate. Each TSC consists of a pair of PV cells having PIN and NIP structures, respectively, with substantially coplanar position of a P-doped layer of one of the cells with respect to an N-doped layer of another cell of the pair. A tunnel junction is formed between the cells of the pair by overlapping P-doped and N-doped layers in the area near the common transparent substrate. The alternating PIN and NIP structures are achieved by forming projections in a continuous monolithic structure of one type and filling the spaces between the projections with the material of the inverse structure of the other type.

Abstract: Proposed is the method for forming selective emitters, field-induced emitters, back-surface field regions, and contacts to the functional regions of a solar cell by essentially electrical means and without conventional thermal diffusion and masking processes. The process includes forming conductive layers on both sides of an intermediate solar-cell structure, performing electrical and thermal treatment by passing electrical current independently through the front-side conductive layer and the back-side conductive layer, thus forming the selective emitters, the selective BSF regions, selective emitter contact regions, and contacts to the selective BSF regions. The obtained structure is then subjected to pulse electrical treatment by applying a voltage pulse or pulses between the front and back conductive layers to form the field-induced emitter and the field-induced BSF region. After the conductive layers are removed, a final solar cell is obtained. The proposed method can significantly simplify manufacturing, reduce cost, and increase throughput in the field of semiconductor fabrication.

Abstract: An integrated demultiplexer/photoreceiver (IDP) for optical networks and optical interconnection devices has a common substrate which supports three sequentially arranged basic components: a waveguide grating router, an array of photodetectors, and an array of heterojunction transistors. Basic layers of all three components are grown together in a common epitaxial process, and then each of the components is individually patterned in accordance with its function. Such structure of IDP makes it possible to reduce the cost, simplify the design, improve conditions for optical alignment, and reduce optical losses. In accordance with one embodiment of the invention, transparency of the optical signal transmission layer of the WGR is controlled by selectively doping the layers of the multiple-layer waveguide structure, while in another embodiment such control is achieved by changing the width of the energy gap in the optical signal transmission layer of the WGR. Such a change is achieved by utilizing electrical bias and optical pumping from an external light source operating on a predetermined wavelength. The invention also provides a method for controlling transparency of the layer that transmits optical signals through the waveguide units in optoelectronic devices, such as an integrated demultiplexer/photoreceiver for optical network, by utilizing optical pumping and electrical bias.
