Luminescent solar concentrator (LSC) is a device for harvesting solar energy that comprise of highly transparent waveguide with fluorescent materials which can absorb the light and re-emit at longer wavelength. As a promising technology, LSC can be utilized to amplify the efficiency and reduce the cost of photovoltaic devices. However, some challenges need to be overcome before its utilization in real-life application including to find the suitable fluorophores. Perylene tetracarboxylic dianhydride (PTCDA) is emerging as a potential candidate for carbon-based electronic devices since they possess tunable optical properties. Nevertheless, reabsorption due to the small Stokes shift and the π−π stacking should be avoided to prevent aggregation formation in using PTCDA. In this study, PTCDA in different concentrations were combined with various materials such as polymer and silica matrix. The experimental results show that using different matrices could affect the optical properties of PTCDA composites. Here, we found that PTCDA embedded in silica matrix exhibit wide absorption spectra, highly transparent, and high solid-state quantum yield (~75%). Furthermore, the LSC demonstrate an apparent edge emission under UV illumination which indicate that our LSC have high optical quality. These results evince that there is a huge potential to significantly improve LSC efficiency further.
