The invention relates to a solar heat collector of a biconcave honeycomb cave hollow structure. The solar heat collector comprises a heat collector plate core, a light-transmitting cover plate, a heat preservation layer and a frame. The bottom of the heat collector plate core is embedded into the heat preservation layer, the upper surface of the heat collector plate core is covered with the light-transmitting cover plate, a back plate is arranged at the bottom of the heat preservation layer, the heat collector plate core is composed of a sunny panel and a bearing panel, the sunny panel and the bearing panel are in smooth connection and are sealed on the peripheries, and therefore a hollow interlayer is formed between the sunny panel and the bearing panel, and the sunny panel is a honeycomb panel formed by a plurality of concave honeycombs. A water inlet and a water outlet are formed in the back of the bearing panel. The honeycomb cave design is adopted, so that the effective illumination area of the solar heat collector is improved by more than 1.8 times, and the capacity of absorbing sunlight radiation is improved. Sunlight irradiates the inner walls of the concave honeycombs, and is absorbed, reflected and absorbed by the inner walls many times, and almost all the sunlight radiation can be absorbed.
