The study on the efficiency increase to the light-concentrating panels

In the study, we design a light-concentrating panel that can collect the sunlight to illuminate the indoor spaces. In addition, we improve the light-concentrating efficiency of the light-concentrating panels by coating the anti-reflection layer over the panels. The simulation results show that the light-concentrating efficiency of the light-concentrating panels is about 31.35%, and it can be increased to 38.77% by coating the anti-reflection layer over the panels.
