the sun battery tomorrow since entering the 21st century, solar photovoltaic (pv) in the rapid development in our country, the efficiency of the solar cell is improving, with the help of nanotechnology, silicon conversion rate could reach 35% in the future. This will become a 'breakthrough' of the solar power generation technology. Material is silicon solar pv electricity he mainstream, so the conversion rate of the silicon has been is important for restricting the further development of the industry. The classical theory of silicon conversion limit is 29%. And in the laboratory's record is 25%. Are of the technology industry. At present. Spend a lot of the production of photovoltaic solar cell components around the conversion rate of 16%. Laboratory can be derived directly from the silica high purity silicon, without having to convert it to metal silicon. To extract from silicon. This reduces the intermediate links, improve efficiency. To combine the third generation of nanotechnology and the existing technology, can put the silicon conversion rate up to 35%. If put into large-scale commercial production. Will greatly reduce the cost of solar power. Is the good news is, this technology 'has been done in the laboratory, LED street light, waiting for the process of industrialization. For solar cell conversion rate 35%, means that solar cell conversion rates than the doubled; Is the same area of solar cell module generating capacity will be doubled. According to national standard 'solar photovoltaic lighting total technical specifications) ( GB24460 - 2009). Of solar battery components and the relationship between the light source power, the power of solar battery components must be 4 - the power of the light sources 5 times. And only need to 2 - in the future 2. Five times. Like this. In the main trunk road, even the use of solar energy street light can be created in the true sense. The sun because of high prices is also a bottleneck for the further development of solar photovoltaic lighting. The good news is. Since 2009, due to the silicon material price dropped substantially. The price of solar cell has fallen by half. It is estimated that the price of solar cell components down to $1 / Wp has been just around the corner, many large solar cell production enterprises in the world put the price as the direction of the efforts.
