Abstract: A solar energy utilization device, comprising a light energy utilization device and at least one liquid light condensing device. The liquid light condensing device is filled with a transparent liquid. The liquid light condensing device has at least one photoreceptor capable of transmitting sunlight into the transparent liquid and a reflector that reflects incident sunlight. In the liquid light condensing device, the sunlight that is reflected by the reflector and then transmitted to the photoreceptor from the transparent liquid forms a total reflection phenomenon, such that the sunlight is prevented from being refracted from the photoreceptor after being reflected by the reflector into the transparent liquid. Thus more sunlight is condensed onto a light energy utilization part of the light energy utilization device, thereby improving the light condensing efficiency.
