It has obvious advantages over the conventional form of photovoltaic power generation. Considering the fact that the solar energy flow density is low and intermittent, the form of middle and low temperature solar energy utilization based on organic Rankine cycle was proposed in this paper. The working principles and current situation in research and development at home and abroad of each technology were introduced in detail, from the aspects of heat collection, energy transformation and heat storage. Meanwhile, the existing problems were pointed out as well. It reveals a broad prospect of solar thermal power generation. Key words: solar energy, s
