  Abstract

Transparent polylactic acid (PLA) fi bers with Lumogen Red 305 (LR305) were prepared by melt spinning. The crystallization and melting behavior, absorbance spectra, emission spectra, mechanical properties, and the concentrator eff ect for a real solar cell of the PLA/LR305 fi bers were characterized by diff erential scanning calorimetry (DSC), UV밮is밡IR spectrophotometer, FL spectrophotometer, yarn tensile tester, and a digital multimeter (Victor VC980 + ), respectively. The results showed that the hot drawing improves the mechanical properties of the fi bers while maintaining the optical properties. When the concentration of LR305 was 0.05 wt%, the breaking strength of the stretched fi ber 22@217 (22% crystallinity, 217 diameters) and the as-formed fi ber 3@205 (3% crystallinity, 205 diameters) were 69.3 and 182.7 MPa, respectively. Meanwhile, the absorbance intensity and luminescence intensity of 22@217 decreased only 6 and 11% compared with 3@205. When triple-drafted PLA/LR305 fi bers with a concentration of 0.25 wt% were combined with the solar cell, the solar cell output current changed from 0 to 2.8 關A.
