Solar energy utilization apparatus

A solar energy utilization apparatus, comprising:

• a light energy utilization unit having a first light energy utilization part and a second light energy utilization part that are capable of receiving, converting and utilizing solar light, the first light energy utilization part and the second light energy utilization part being arranged back to back;
• a liquid light-condensing unit in an axially symmetric structure or a rotating structure, the liquid light-condensing unit having an accommodating cavity filled with a transparent liquid and provided with a transparent top wall and a transparent bottom wall,
• the transparent top wall being a light receiving surface for receiving sunlight from outside, the width of the light receiving surface being greater than the width of the first light energy utilization part and/or the second light energy utilization part;
• and
• a reflection groove with a reflecting surface arranged on an inner wall thereof, the liquid light-condensing unit being arranged in the reflection groove with at least partially the transparent bottom wall being apart from a bottom wall of the reflection groove, the second light energy utilization part being arranged towards the reflecting surface, such that a part of the sunlight is allowed to be transmitted from the liquid light-condensing unit onto the reflecting surface and, by means of the reflecting surface, reflected back into the liquid light-condensing unit or reflected onto the light energy utilization unit, and a part of the sunlight in the accommodating cavity transmitted from the transparent liquid to the transparent top or bottom wall forms a total reflection phenomenon to concentrate the sunlight onto the light energy utilization unit;
• wherein the first light energy utilization part is arranged at an outer side of the transparent bottom wall, the transparent liquid guides the sunlight onto the first light energy utilization part, and the reflecting surface is capable of reflecting at least part of the sunlight onto the second light energy utilization part.
