摘要： The present invention relates to a modified perovskite comprising a polymer that co-crystalizes with perovskite. In particular instances, the polymer is chosen from poly(ethylene oxide) (PEO) or polyethylenimine (PEI). A modified perovskite film includes an ionic salt; and a perovskite having the formula ABX3, wherein counter anions of the ionic salt interact with A and counter cations interact with X, such that ion migration is suppressed.

摘要： Perovskite hybrid solar cells utilize a bulk heterojunction (BHJ) active layer that is formed as a composite of an organometal halide perovskite and a water soluble fullerene, such as A10C60. In alternative embodiments, the BHJ active layer may be formed as a composite of an organometal halide perovskite material and a fullerene, such as PC61BM. Thus, the fullerene acts as an electron extraction acceptor within the BHJ, allowing such solar cells to more efficiently transport the electrons from the fullerene/perovskite interface to a fullerene-based electron transport layer (ETL). As a result, increased fill factor (FF), as well as improvements in the short-circuit current density (JSC) and power conversion efficiency (PCE) are achieved by the solar cells.

摘要： A photodetector includes an active layer formed of an inorganic/organic hybrid perovskite material, such as organometal halide perovskites. The perovskite hybrid photodetector provides low dark-current densities and high external-quantum efficiencies, resulting in a photodetector with enhanced photoresponsivity and detectivity. Advantageously, the perovskite hybrid photodetector may be prepared by solution processing, and is compatible with large-scale manufacturing techniques.

摘要： Methods, compositions and articles of manufacture involving soluble conjugated polymers are provided. The conjugated polymers have a sufficient density of polar substituents to render them soluble in a polar medium, for example water and/or methanol. The conjugated polymers may desirably comprise monomers which alter their conductivity properties. The different solubility properties of these polymers allow their deposition in solution in multilayer formats with other conjugated polymers. Also provided are articles of manufacture comprising multiple layers of conjugated polymers having differing solubility characteristics. Embodiments of the invention are described further herein.

摘要： A broad-band photodetector utilizes perovskite hybrid material and quantum dots as light harvesters. In particular, the photodetector is configured so that the structural defects on the surface of a quantum dot layer are passivated with perovskite hybrid material. As a result, the trap states on the surface of the quantum dot material is reduced, allowing leakage currents in the quantum dot material to be significantly reduced. As such, the photodetector is able to achieve broad-band operation, with enhanced photoresponsitivity and detectivity.

摘要： A PEDOT:PSS film having enhanced thermoelectric properties is doped with DMSO and a binary secondary dopant, such as PEO. The composition of such film causes the ratios of PEDOT in bipolaron states to be increased. As a result, the Seebeck coefficient, the electrical conductivities, and power factor of the film are increased, thereby increasing the efficiency of the film. Thus, a thermoelectric device that uses the film is able to achieve enhanced operating performance.
