The invention discloses a multi-functional
solar energy utilization
system which comprises a light-
electricity conversion module, a heat-
electricity conversion module, a heat absorbing module and a purifying module, wherein the light-
electricity conversion module is used for converting
optical energy to electricity energy according to the principle that electricity can be generated through light, the heat-electricity conversion module can convert
heat energy to electricity energy, the heat absorbing module can be used for heating fluids, and the purifying module can purify the fluids by means of the
photocatalysis principle. By means of the arrangement of a thermoelectric power generation piece, heat and electricity conversion is achieved, meanwhile, by means of
temperature difference generated due to the fact that the upper surfaces of the fluids are heated, self-circulating heating of the fluids is achieved, and the
utilization rate of
solar energy is improved to a great extent by means of the multi-functional
solar energy utilization
system. The invention further comprises a purifying function module for purifying the fluids, and the purifying function module can purify the heated fluids through self-circulating. The invention provides the
system capable of making use of the solar energy comprehensively, the photovoltaic utilization efficiency is high, a self-circulating
processing device is arranged, and accordingly cost is low.
