Abstract: According to a main objective of the present invention, the three-dimensional arrangement of solar cells is adjusted so as to use sunlight directly coming from the sun mainly for solar power generation while transmitting wavelengths necessary for the growth of plants and reflecting wavelengths unnecessary for or hindering the growth of plants among wavelengths of sunlight passing through the solar cells to use the reflected wavelengths for additional solar power generation.
Sunlight reflected by the dichroic optical filter may be used to additionally generate electricity using solar cells provided perpendicular to the dichroic optical filter, thereby maximizing the use efficiency of sunlight.

Abstract: The present invention relates to a porous particle composite for PCR, wherein the porous particle composite distributes photothermal nano-elements that generate heat by absorbing light in porous particles in which nucleic acid amplification occurs through temperature control so as not to adjust the temperature of the entire sample by using a hot plate or the like but to adjust the temperature inside the particles by irradiating light to the porous particles to allow nucleic acid amplification inside thereof, thereby reducing energy consumption and shortening diagnostic time.

Abstract: The present disclosure relates to a polybenzimidazole-based electrolyte membrane for alkaline water electrolysis, which includes a polybenzimidazole-based polymer, wherein the polybenzimidazole-based polymer is a biaxially oriented film. The polybenzimidazole-based electrolyte membrane for alkaline water electrolysis can reduce the concentration of an alkaline solution by improving the crystallinity of a polybenzimidazole-based polymer to increase the resistance against base, significantly improving the long-term stability of alkaline water electrolysis using a polybenzimidazole-based electrolyte membrane through the improved resistance against base, and by increasing the operation temperature to enhance the catalyst activity.
