摘要： Methods of making a photovoltaic device with an organic liquid precursor having electron donor, electron acceptor, and liquid carrier are provided. The liquid precursor is applied to an electrode. A gas permeable layer/stamp contacts and applies pressure to the organic liquid precursor removing liquid carrier to form a solid active material with uniform interpenetrating network domains of electron donor/acceptor materials. A two-step process is also contemplated. A liquid precursor with either electron donor or acceptor is applied to an electrode, contacted under pressure with a first stamp having a nanoscale pattern, thus forming a solid with a patterned surface. Then, a second liquid precursor with the other of the electron donor or acceptor is applied to the patterned surface, contacted with a second stamp under pressure to form the active material. A transparent conducting electrode with material nanograting can be formed. The methods also include continuous processing, like roll-to-roll manufacturing.

摘要： A plasmonic optical spectrum filtering device is provided that filters electromagnetic waves by optical resonance, for example, by selective conversion between the free-space waves and spatially confined modes in plasmonic nano-resonators. Frequency-selective transmission and reflection spectra are engineered and can be used as spectrum filters for display and imaging applications. A thin film stack color filter is further disclosed, which can be designed to either function as a transmission color filter with efficiency twice that of conventional colorant based color filter; or as a reflective color filter for display devices (e.g., used in an energy harvesting reflective display). In other variations, a novel reflective colored display is viewable under direct sunlight, and can simultaneously harvest both incident light and generate electrical power. Methods of making such plamonic optical spectrum filtering devices are also provided.

摘要： Electromagnetic interference (EMI) shields and methods for broadband EMI shielding are provided. An EMI shield disposed in a path of electromagnetic radiation blocks a broad range of frequencies (> about 800 MHz to to 20 dB, while transmitting wavelengths in a visible range to an average transmission efficiency of > about 85% through the electromagnetic shield. The shield includes a flexible stack comprising a continuous ultrathin metal film comprising silver (Ag) and copper (Cu) and two antireflection dielectric layers disposed on either side of the ultrathin metal film. The shield may also include multiple stacks or an optional graphene layer that may be spaced apart from the flexible stack to achieve radiofrequency (RE) absorption, which provides additional form of EMI shielding. The EMI shield can be made via roll-to-roll sputtering.
