Journal ArticleDOI
Wide optical spectrum range, sub-volt, compact modulator based on electro-optic polymer refilled silicon slot photonic crystal waveguide
TL;DR: In this paper, a band-engineered electro-optic (EO) polymer refilled silicon slot photonic crystal waveguide (PCW) modulator was designed and demonstrated.
Journal ArticleDOI
Two-photon absorbing block copolymer as a nanocarrier for porphyrin: energy transfer and singlet oxygen generation in micellar aqueous solution.
TL;DR: It is demonstrated that hydrophobic porphyrin could be incorporated into aqueous solution with the assistance of micelles and contributes to the efficient generation of the singlet oxygen from the porpharin guest molecules.
Journal ArticleDOI
Halogen-free solvent processing for sustainable development of high efficiency organic solar cells
TL;DR: In this article, 2% 1-methylnaphthalene (Me-naph) was used as a processing additive to toluene to solve the solubility problem of PC71BM.
Journal ArticleDOI

TL;DR: A nonfullerene acceptor based on a 3D tetraperylene diimide is developed for bulk heterojunction organic photovoltaics and a significant improvement of power conversion efficiency can be achieved.
Journal ArticleDOI
Highly Efficient Semitransparent Solar Cells with Selective Absorption and Tandem Architecture
TL;DR: By sequentially reducing the visible absorbing component in a low-bandgap organic bulk-heterojunction layer, an ST-PV with selective absorption in the NIR is achieved with a power conversion efficiency of 5.9% and a high AVT of 62%.
