Abstract/Summary:

---

Luminescent solar concentrator (LSC) devices have been in development for nearly fifty years, usually aiming at enhanced combinations of luminophores and photovoltaic solar cells. In this research, the focus is on the development of new geometric designs of LSC PV devices to improve the performance. The research has been executed by LSC device ray-tracing simulation using software LightTools for LSC PV configurations with a PMMA lightguide doped with Lumogen Red 305 dye. The set of LSC models evaluated have different sizes, different dye concentrations and silicon PV cells on the backside and along all four edges. The simulation results show that with changes in size from 10 to 1,000 mm and dye concentration from 5 to 100 PPM, a 5 mm thick LSC planar light guide can have a total optical efficiency in the range of 77% to 90%. Moreover, a curved LSC lightguide with a dye concentration of 100 PPM also provides a good performance with provided 81% optical efficiency at the backside.
