  • ORGANIC SOLAR CELL INCLUDING DUAL LAYER TYPE CHARGE TRANSPORT LAYER HAVING ENHANCED PHOTOSTABILITY, AND MANUFACTURING METHOD THEREFOR
    Publication number: 20210367174
    Abstract: An organic solar cell having a structure including a dual layer type charge transport layer, which has an ultraviolet blocking layer, is provided. The organic solar cell has a dual layer charge transport layer by including a photostable charge transport layer on one surface or both surfaces of a photoactive layer, thereby having enhanced charge transport capability within the solar cell, improved photostability without an external protection film, and excellent durability. In addition, a method for manufacturing an organic solar cell is provided which forms a photostability charge transport layer on one surface or both surfaces of a photoactive layer, thereby manufacturing a solar cell, which can be stable when exposed to ultraviolet light during electrode formation and has a highly efficient and photostability-enhanced structure in a manufacturing process without a step of attaching a protection glass and a protection film.

  • ANTI-UV COMPOSITION FOR PROTECTING SCALP
    Publication number: 20140341956
    Abstract: Disclosed herein is a anti-UV composition for protecting the scalp. The anti-UV composition for protecting the scalp of the present invention includes a fermented broth of Outtuynia cordata, Perilla frutescens, and Camellia sinensis; a UV blocking agent; and a pigment in an effective amount, respectively, thereby enabling the blocking of UV rays via scattering, reflecting, and absorbing, thus preventing scalp damage and alopecia due to UV while helping to recover scalp health and thus promoting the expression of new hair.
