Solar thermal utilization is one of the most promising technologies in the field of new energy

which has the highest technical contents of its own

the fastest industrialization and the greatest contribution to the market. 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.
