5 results about "Ion migration" patented technology

A cross-flow ion mobility analyzer (CIMA) that includes a component of gas flow that opposes an electric field that is established within a channel, wherein ions are carried through the channel, wherein ions of a specific mobility are trapped by the opposing electric field and flow field within the channel and are detected when the ions reach the end of the channel, wherein a detector at the end of the channel sees a continuous stream of mobility-selected ions, and wherein different ions are selected by modifying the electric field and / or the velocity of the flow field.

The invention discloses a solar cell which comprises a substrate, the surface of the substrate is provided with a suede structure, and the substrate is provided with a carrier transport layer and a perovskite absorption layer which are arranged in a stacked mode. An interface passivation layer is arranged between the perovskite absorption layer and the carrier transmission layer, and the interface passivation layer and the suede structure are conformal. The invention also provides a preparation method of the solar cell. According to the solar cell provided by the invention, the interface passivation layer and the textured surface of the substrate are conformal, so that uniform and compact deposition of the interface passivation layer and the textured surface of the substrate is realized, ion migration is inhibited, and hysteresis of a positive scanning curve and a negative scanning curve of the cell is remarkably reduced; and meanwhile, the conformal structure of the interface passivation layer continues the good light trapping structure design of the substrate textured surface, the light reflection loss is reduced to the maximum extent, and the photo-generated current is remarkably improved.

The invention relates to an inorganic electrochromism ion transport layer and assembly composite film system preparation method, which is characterized in that a WO3-based film, an AlPO4-based film, a NiO-based film and a TCO layer are sequentially prepared on a glass substrate / TCO layer through a chemical liquid phase method or a magnetron sputtering method, the WO3-based film, the NiO-based film and the TCO layer are prepared through the magnetron sputtering method, and the WO3-based film, the AlPO4-based film, the NiO-based film and the TCO layer are arranged on the glass substrate / TCO layer. The ion transmission layer AlPO4-based thin film is prepared by adopting a magnetron sputtering method or a chemical liquid phase deposition method. The invention has the advantages that: a novel solid electrolyte material, namely an AlPO4-based material, is adopted as the ion transmission layer; and the AlPO4-based ion transport layer can be prepared by adopting a chemical liquid phase deposition method. Compared with a radio frequency mode needed by magnetron sputtering, the liquid phase method is lower in cost and higher in efficiency. Meanwhile, the AlPO4-based ion transport layer prepared by the liquid phase method enables the film structure to be loose and the ion mobility to be higher due to the characteristics of the preparation method, and the finally prepared assembly has higher color changing efficiency.
