Optical wireless power transmission characteristics of surface appearance controlled solar cells using visible colour filters

Abstract: Optical wireless power transmission (OWPT) systems are attractive photonic systems based on light sources and solar cells. To improve the visual design of practical consumer applications, we applied visible colour filters to change the normal black appearance of solar cells. Different colours made by multilayer‐type filters on solar cells were investigated for control of visible colour with maintained power transmission efficiency. The surface colours seen by the eyes and standard cameras were controlled by th… Show more

“…In particular, the 2D-array VCSEL covers high output power of 1 watt or more, and various power applications have begun to become important fields. As one of them, optical wireless power transmission (OWPT), which has the advantages of long-distance transmission and no electromagnetic interference, is an attractive high-power photonic application [2][3][4][5][6][7], and high-power VCSELs are its important light source [8,9]. The power transmission efficiency of OWPT is proportional to the power conversion efficiency (PCE) of the light source.…”
