A flexible double-junction solar cell includes a flexible substrate including a lower electrode layer, an InGaAs solar cell disposed to be in contact with the lower electrode layer of the flexible substrate, and a GaAs solar cell disposed on the InGaAs solar cell and connected to the InGaAs solar cell in series. The GaAs solar cell includes a metal nanodisk array disposed on a lower surface thereof and a void array, aligned with the metal nanodisk array, is disposed below the metal nanodisk array.

Flexible double-junction solar cell

A tandem solar cell includes a substrate a plurality of sub-cells stacked on the substrate and configured to sequentially perform photoelectric conversion with different wavelength band, and a metal disk array disposed on at least one of interfaces between adjacent sub-cells. A center wavelength of wavelength bands corresponding to the sub-cells gradually decreases as progressing downward with respect to an uppermost layer. The metal disk array reflects a light transmitting a sub-cell disposed over the metal disk array without being absorbed therein. The metal disk array is inserted by means of wafer bonding.

Tandem solar cell including metal disk array

Provided are a pharmaceutical composition with improved stability including palonosetron, a preparation method thereof, and a pharmaceutical package including the pharmaceutical composition.

Pharmaceutical composition containing palonosetron

The present invention relates to an ionic multi-block copolymer composition comprising tri-block copolymers having a polypropyleneoxide or polybutyleneoxide block positioned between two polyethyleneoxide blocks and the tri-block copolymers are connected through dicarboxylic acid linkages forming a multi-block copolymer having a weight average molecular weight of more than 40,000 Dalton. The higher weight average molecular weight enables the hydrolgel formed from the multi-block copolymer of the present invention to maintain its gel status for more than several days.

Biodegradable multi-block polymeric composition capable of sol-gel transition and pharmaceutical composition comprising the same

A composition for the sustained delivery of a drug comprising an amphiphilic diblock copolymer; a poorly water-soluble drug; a biodegradable polymer; and liquid poly(ethylene glycol) or functional derivatives thereof and a process for preparing the composition are disclosed. When administered into a particular body site, the composition forms an implant containing the drug and drug containing polymeric micelles, which are slowly released from the implant to maintain a constant drug concentration for an extended period of time.
