摘要： In exemplary implementations of this invention, a photoelectrode includes a semiconductor for photocarrier generation, and a catalyst layer for altering the reaction rate in an adjacent electrolyte. The catalyst layer covers part of the semiconductor. The thickness of the catalyst layer is less than 60% of its minority carrier diffusion distance. If the photoelectrode is a photoanode, it has an OEP that is more than the potential of the valance band edge but less than the potential of the Fermi level of the semiconductor. If it is a photocathode, it has an RHE potential that is less than the potential of the conduction band edge but more than the potential of the Fermi level of the semiconductor. The absolute value of difference (OEP minus potential of valence band edge, or RHE potential minus potential of conduction band edge) is greater than zero and less than or equal to 0.2V.

摘要： A method of forming an ordered nanorods array in a confined space is used to form a high surface area device where an ensemble of parallel trenches has micrometer dimensions for the width and depth of the trenches, which are decorated with crystalline nanowires radiating from the sidewalls and bases of the trenches. The high surface area device is formed by depositing a conformal crystalline seed coating in the trenches, forming microchannels from these trenches by placing a barrier layer on the open surface of the trenches, contacting the conformal coating with a crystal precursor solution that is caused to flow through the microchannels. In an embodiment, a very high surface area electrode is constructed with ZnO nanowires radiating from the sidewalls and base of trenches formed on a silicon substrate. The device can be a dye-sensitized solar cell.

摘要： Photovoltaic devices such as solar cells, hybrid solar cell-batteries, and other such devices may include an active layer disposed between two electrodes. The active layer may have perovskite material and other material such as mesoporous material, interfacial layers, thin-coat interfacial layers, and combinations thereof. The perovskite material may be photoactive. The perovskite material may be disposed between two or more other materials in the photovoltaic device. Inclusion of these materials in various arrangements within an active layer of a photovoltaic device may improve device performance. Other materials may be included to further improve device performance, such as, for example: additional perovskites, and additional interfacial layers.

摘要： The invention provides an optoelectronic device comprising a porous material, which porous material comprises a semiconductor comprising a perovskite. The porous material may comprise a porous perovskite. Thus, the porous material may be a perovskite material which is itself porous. Additionally or alternatively, the porous material may comprise a porous dielectric scaffold material, such as alumina, and a coating disposed on a surface thereof, which coating comprises the semiconductor comprising the perovskite. Thus, in some embodiments the porosity arises from the dielectric scaffold rather than from the perovskite itself. The porous material is usually infiltrated by a charge transporting material such as a hole conductor, a liquid electrolyte, or an electron conductor. The invention further provides the use of the porous material as a semiconductor in an optoelectronic device. Further provided is the use of the porous material as a photosensitizing, semiconducting material in an optoelectronic device. The invention additionally provides the use of a layer comprising the porous material as a photoactive layer in an optoelectronic device. Further provided is a photoactive layer for an optoelectronic device, which photoactive layer comprises the porous material.

摘要翻译： 本发明提供一种包括多孔材料的光电子器件，该多孔材料包括包含钙钛矿的半导体。 多孔材料可以包括多孔钙钛矿。 因此，多孔材料可以是本身是多孔的钙钛矿材料。 另外或替代地，多孔材料可以包括多孔介电支架材料，例如氧化铝，以及设置在其表面上的涂层，该涂层包括包含钙钛矿的半导体。 因此，在一些实施方案中，孔隙率来自电介质支架而不是钙钛矿本身。 多孔材料通常由诸如空穴导体，液体电解质或电子导体的电荷输送材料渗透。 本发明还提供了多孔材料在光电器件中作为半导体的用途。 进一步提供的是使用多孔材料作为光电子器件中的光敏半导体材料。 本发明另外提供了包含多孔材料的层作为光电器件中的光活性层的用途。 还提供了一种用于光电子器件的光敏层，该光敏层包括多孔材料。

摘要： Disclosed are a nanostructure array substrate, a method for fabricating the same, and a dye-sensitized solar cell by using the same. The nanostructure array substrate includes a plurality of metal oxide nanostructures vertically aligned on the substrate while being separated from each other. The metal oxide nanostructures include nanorods having a ZnO core/TiO2 shell structure or TiO2 nanotubes. The method includes the steps of forming ZnO nanorods vertically aligned from a seed layer formed on a substrate; and coating a TiO2 sol on the ZnO nanorods and sintering the ZnO nanorods to form nanorods having a ZnO core/TiO2 shell structure. The transparency and flexibility of the substrate are ensured. The photoelectric conversion efficiency of the solar cell is improved if the nanostructure array substrate is employed in the photo electrode of the dye-sensitized solar cell.
