Fig. 6From: The Fabrication of Nanoimprinted P3HT Nanograting by Patterned ETFE Mold at Room Temperature and Its Application for Solar CellThe UV-vis absorbance spectra of PBHJ and OBHJ films. Parallel and vertical are referred as measurements performed with nanograting line direction parallel and perpendicular to the direction of incident light. The line width of P3HT nanograting is ~130 nm within the OBHJ structureBack to article page
