Flat luminescent solar concentrator PV (LSC-PV) devices have been developed for nearly fifty years. However, in order to enhance their integration potential in buildings and vehicles, this study is focused on bent LSC-PV devices. LSC PV modules with a 20x20 cm2 top view area and 6 different curvatures (k, from 1 to 10 m-1) have been designed in Solidworks and simulated by means of ray tracing in LightTools. These modules are 20mm thick, are made of PMMA with 110 parts per million (ppm) of Lumogen Red 305 dye, and have silicon solar cells attached only to their rectangle edges with a total PV cells area of 80 cm2 per module. The simulation result shows a better optical and therefore electric performance for the bent LSC-PV modules than for flat planar modules. The performance increases with the increase of curvature, for instance, an LSC-PV module with a curvature of k=10 m-1 is 40% more efficient than a flat reference. Furthermore, in this study, the effect of reflection layers and sizing of the front surface of the LSC PV modules on their performance is investigated.
