China PV pursuit of the story of the right to speak epic, but the determination of the price is due to non-simple human, but it is the interaction of a variety of market factors. In April 2012, Xinyu City and Jiangxi LDK Solar Hi-Tech Co., Ltd. jointly invest 10 billion, China Xinyu photovoltaic market "is expected to opening the size of its design, the next number of years I'm afraid no one can out Right. Can it hope to establish the right to speak its mind and not Xinyu and Zevi said even if the current operation of the market situation is not ideal. 

2013, a change from the past "two out" situation, the crown of the world's largest photovoltaic power plant construction country, I am afraid that no one can compete, and hydropower, wind power to become the global total is not a dream. Plus the world's largest production capacity, I am afraid that the Chinese want to do not the right to speak will not work. 

The total PV does not require subsidies day China as the world's most competitive country, indeed should scientific planning under full market conditions, the price of voice. In addition to the constant improvement of China's market economy system, continue to strengthen the PV solar cell industry market system should also be on the agenda, such as: to develop the market system, the establishment of a price index; strengthen the financial role in the establishment of commodity futures; perfect Association role to strengthen the unity of will and so on. When fully market-oriented the photovoltaic industry came when China should fight for a real voice. 

Miao Lei: Rice University researchers have given conclusion under in of 1atm (standard atmospheric pressure), steam can reach 100 ℃. From the perspective of solar thermal conversion, which is incredible. Of course, based on the above, I talked about the principle, we can easily find, will vary with the different experimental conditions, the temperature of the water vapor. 

The heat generated by the example, the same area of ​​the nanoparticles are highly focused sunlight, will certainly direct sunlight and relatively dispersed heat generated is not the same, the natural water the temperature of the steam will be different.From the current published data than the condenser temperature, light area, and other key indicators have not clearly recorded, so we can not be precise to conclusions. 

Reporter: In recent years the use of solar energy technology after another, and the efficiency of solar charge controller energy conversion has been a focus of concern in this field. Then we talked about the technology and how efficient? 

Lei Miao: The research team of scientists believe the technology to be able to approximately 80% of the solar energy into steam energy. If the steam turbine power generation through the current, then the overall efficiency can reach 24%. We are more familiar with photovoltaic solar panels, energy efficiency is usually about 15%.The researchers believe that, with the further improvement of the technology, efficiency, there is still room for improvement. 

In fact, the efficiency of the solar absorption of the nanoparticles in the liquid up to about 90% are possible, but the problem is that the conversion efficiency after the absorption of heat, this section has not been tested, and can not easily evaluation.
