We proposed a liquid crystal (LC) alignment design method and a device structure to achieve planar microtracking for sunlight using LC lenses. Through the analysis of LC alignment and diffracted light, we confirmed a high intensity of focused light along a single plane in the proposed liquid crystal alignment.
