Abstract
Deoxyribonucleic acid (DNA) has a unique double helix structure that may be of great importance in optoelectronic devices and applications. The feature of spatially organizing light sensitive molecules makes DNA a promising template for efficient F¨orster resonance energy transfer (FRET). In the first part of this study, long range and cascaded energy transfer in DNA biopolymer films was studied and characterized, where the effects of different dyes, dye concentrations and different hosts were examined. In the second part of the study, multiple dyes-doped DNA biopolymer films were studied in the application of luminescent solar concentrator (LSC) for wavelength conversion to enhance efficiency of solar cells. RET mediated DNA biopolymer films based on various parameters were investigated and the characteristics of LSC were discussed.
