40、s stage, the research focus of solar energy in the world were still on the solar-powered device which variable photospot method were applied and flat plate heat collector and low boiling point actuating me
41、dium were started to use; the capacity of the device was gradually expanded with the max. output power of 73.46kW; device was utilized with the definite end-use and in higher cost.</p><p> The typical built

43、ne built in U.S in 1902 to 1908 which employed the flat plate heat collector and low boiling point actuating medium; 1 set of solar energy pump comprised of 5 parabolic mirror in a length of 62.5m, width of 4m built in C
44、airo of Egypt in which the total light collecting are</p><p> 2. The Second Stage (1920-1965)</p><p> For these 20 years, the research of solar energy was implementing on the poor st
45、age, which the mandate to participate in the development and the research projects had been widely declined due to the mass utilization of fossil fuels and the second world war (1935---1945) while the solar energy couldn
46、’t satisfy the urgent demand upon the energy. Therefore, the research and development of solar energy was due to be gradually deserted.</p><p> 3. The Third Stage (1945-1965)</p><p> For
47、these 20 years after the Second World War, some foresight person has noticed that the petroleum and natural gas resources had been rapidly decreased and called for attention on these issues in order to gradually promote
48、the recovery and development of the solar energy research. Solar energy institutes were setup and academic exchanges and exhibitions were held which raised the research upsurge again on solar energy.</p><p>
49、 In this period, great progress was achieved in the research of solar energy, in particular: the foundation theory of selective paints proposed in the First International Solar Thermal Academic Conference in 1955, which
50、 black nickel had been developed as the practical selective paints, contributing to development of high-effective heat collector; the practical silicon solar cells developed by Bell Lab in U.S in 1954 which laid the foun
51、dation for large scale utilization of photovoltaic generation.</p><p> Furthermore, there were still other significant results, including:</p><p> a. One set of 50kW solar stove
52、 was built by French National Research Center in 1952;</p><p> b. The worldwide prototype ammonia-water absorbing air conditioning system heated by flat plate heat collector with the capacity of 5 tons was
53、built in Florida of U.S in 1960;</p><p> c. An engine equipped with silicon window was invented in 1961.</p><p> In this stage, research on foundation theory and foundation material of solar e
54、nergy was reinforced and academic breakthrough, i.e. selective paints and silicon solar cells were achieved. The flat plate had been well developed and ripe in technologies. Progress had been achieved in the research of&
55、#160;solar energy absorbing air conditioners and a batch of pilot solar room was established. Preliminary research was conducted on the engine and tower type solar-powered generation technologies.</p><p&g
56、t; 4. The Fourth Stage (1965---1973)</p><p> In the stage, the research work on solar energy was standstill due to the reason that the utilization technologies of solar energy had entered into the growing
57、stage which was no ripe in process, heavy in investment and lower in effect. Thus it cannot compete with conventional energy, which resulted in the absence of attention and support from the public, enterprise and governm
58、ent.</p><p> 5. The Fifth Stage (1973---1980)</p><p> After petroleum played a leading role in the worldwide energy structure, it has been a key factor to control the economic and determine th
59、e fatal, development and declining of a country. After the explosion of Middle East War at Oc., 1973, OPEC employed the method of declining the production and increasing the price to support the struggle and safeguard th
60、e national benefits which resulted in heavy economic attack for those countries that relied on importing large amount of inexpensive petroleum</p><p> From that on, many countries, especially the industrial
61、ized countries turned their attention towards the support on the research and development of solar energy and other renewable energy technologies. The upsurge of developing and utilizing solar energy had been raised agai
62、n in the world. In 1973, U.S drew up a government scale sunlight power generation program which the research budget for solar energy were increased in a large amount, and solar energy development bank was to established
63、to fa</p><p> The upsurge on the utilization of solar energy raised in 1970s in the world also impacted on China. Some foresight technicians started to devote to the solar energy industry one after another
64、and positively proposed to the relative department of the government and published books and periodicals to introduce the international trends on the utilization of solar energy. Solar stove was popularized and
65、 utilized in countryside; solar water heater was launched in the city; solar cells used in space h</p><p> During this period, research and development of solar energy entered into an unprecedented well-dev
66、eloped stage with the following characteristics:</p><p> a. Each country enhanced planning on solar energy research. Many countries worked out short term and long-term sunlight program. The utiliz
67、ation of solar energy had been a governmental action with intensive support. The international cooperation was very active which some developing countries had started to participate in the utilization of solar energy.<
68、;/p><p> b. The research field was expanding; research work was developed day by day and significant results achieved, for example, CPC, vacuum heat collecting pipe, non-crystal silicon solar cells, water-phot
69、olyzed hydrogen production and solar energy thermal power generation.</p><p> c. The solar energy development program worked out by each country existed the problems that the requirement was too high and ur
70、gent and insufficient expectation on difficulty in implementation. They have thought to replace the mineral energy in the short time and to utilize the solar energy in large scale. For example, U.S has once scheduled to
71、build a small size solar energy demonstration satellite power station in 1985 and one set of 5 million kW space solar energy power station in 1995. In f</p><p> d. Products such as solar water heater
72、160;and solar cells were started to commercialize. The solar energy sector has been preliminarily established with a small scale and ineffective economic effects.</p><p> 6. The Sixth Stage (1980-
73、1992)</p><p> The upsurge on utilization of solar energy emerged in 1970s was fallen into a stage of being developed in a low and slow step in 1980s. Many countries in the world declined the research budget
74、 for solar energy in successive in a large amount, in particular the U.S.</p><p> The main reasons resulted in this situation were that the international oil price was corrected in a large range while solar
75、 energy product cost was still remaining as before which may be of no competitive capability; no any significant breakthrough on solar energy technologies to increase the efficiency and reduce the cost which led to break
76、 down people’s confidence to develop solar energy; increased development on nuclear power which may restrain on a certain degree on the development of solar</p><p> Influenced on the turndown of solar energ
77、y in the worldwide in 1980s, research work in China also declined in a certain degree. Due to the reason that the utilization of solar energy was heavy in investment, ineffective in results, difficult in energy storage a
78、nd large in land covering, solar energy should be considered as the future energy. Some person even proposed that the technology could be introduced after it would be developed successfully. Only few people supported suc
79、h viewpoint, but it</p><p> During this period, although the research budget has been mitigated in a large amount, the research work remained uninterruptedly, among which some projects achieved progress whi
80、ch facilitated people to investigate seriously on the program and goads worked out before and to adjust the research focus so that to strive for great achievement by less input.</p><p> 7. The Seventh Stage
81、 (1992---Until Now)</p><p> Excessive burning of fossil fuel led to worldwide environmental pollution and ecological destruction, which has been threatened the substance and development of human beings. Und
82、er such circumstance, UN held the international environment and development conference in Brazil in 1992. On this meeting, a series of important document were published including the Environment and Development Mani
