United States Patent Patent No.：7,853,102 Polymer Wavelength Filters with High-resolution Periodical Structures and its Fabrication using Replication process Inventor：Kun-Yi Lee (李昆益) E-mail：kelvin@cc.cust.edu.tw Abstract: This invention describes a procedure to replicate a polymeric wavelength filter. In this invention, the grating structure on a polymer is fabricated first using holographic interferometry and micro-molding processes. The polymeric wavelength filters are produced by a two-step molding process where the master mold is first formed on a negative tone photoresist and subsequently transferred to a PDMS mold; following this step, the PDMS silicon rubber mold was used as a stamp to transfer the pattern of the polymeric wavelength filters onto a UV cure epoxy. TAIWAN PATENT Patent No.：M349039 High power conversion efficiency solar cell structure Inventor：Kun-Yi Lee (李昆益) E-mail：kelvin@cc.cust.edu.tw Abstract: This invention have successfully created a light-collecting solar cell structure to promote its power conversion efficiency through coating the surface polymer grating to recollect the repeatedly reflected light. The grating is fabricated using holographic interference lithography and micro molding.
