After the end of World War II 20 years, some visionary people have noticed the oil and gas resources are being rapidly reduced, public awareness of the problem, and gradually promoted the recovery and solar energy research conduct, and the establishment of Solar academic organizations, organizing academic exchanges and exhibitions, the rise of solar energy research boom again. In this phase, solar energy research has made some significant progress, the more prominent are: 1945,United StatesBellLaboratory research into practical silicon solar cells for photovoltaic power generation laid the foundation for large-scale application; in 1955, Talbot and other Israeli solar heat in the first international scientific meeting on the basis of selective coating theory and research into practical Selective black nickel coating, as the development of highly efficient solar collector to create the conditions. In addition, during this period are some other important results, the more prominent are: In 1952, the French National Research Center, Department of Shandong Province in the Pyrenees into a power of 50kW ofSolar furnace. In 1960, Florida in the United States built the world's first flat-plate collector heat applied ammonia - water absorption air conditioning systems, refrigeration cooling capacity of 5 tons. In 1961, one with a quartz windowStirling engineCome out. At this stage, the enhanced solar basic theory and basic materials research, have made, such as solar selective coatings and silicon solar cells and other major technological breakthrough. Flat-plate collector has been greatly developed, mature technology.Solar heater air-conditioningResearch progress, and built a number of experimental Solar house. The Stirling engine of the difficult and tower solar thermal power technology, a preliminary study.
