Thin film technology can print solar panels on aluminum foil

the technology of printing cheap solar panels on aluminum foil has recently appeared, which will become a milestone in the solar industry

the key of nano solar technology is the interlayer of copper, indium, gallium and selenide. The thickness of this sandwich plate is only 1% of that of the silicon plate used in the current solar photovoltaic market. The huge potential of this technology has moved Google founders Sergey Brin and Larry Page. From the early stage of technology development, they have become angel investors in this project

two statements made the debut of nano solar: the company has a contract of $4billion, and their solar panels sell for $1 per watt of special energy. This price is very competitive compared with the current fossil fuel price in the world

in particular, this technology can avoid the difficulties of building huge power stations such as thermal power stations and nuclear power stations. Building many smaller solar power stations in adjacent cities has become another choice for people

solar panels such as the performance and required products we test according to the needs of flexible packaging film have a high return on investment, and the configuration can be arbitrarily selected from 2 MW to 20 MW. If power consumption is urgent, people may find that some discolored walls with new uses are rising sharply. Such a municipal power plant can be built in six months and directly transmit electricity to local electricity without large-scale transmission investment. Martin rothcherson, CEO of solar energy company, wrote in an email to the connection station. Thermal power and nuclear power cannot compete with it in terms of return on investment and rapid production

since this solar energy technology is regarded as a real breakthrough, thin-film solar energy technology has become the main focus of alternative energy research in the United States since the early 1980s. Silicon battery is easy to produce, reliable and efficient, but some researchers believe that silicon battery also has its inherent defects. Producing silicon cells requires more silicon than thin-film solar cells. And even if it can achieve a photoelectric conversion rate of 40%, its efficiency is far lower than that of fossil energy fuels

the National Renewable Energy Laboratory has been committed to the research of thin-film solar energy in the 1990s, but it seems that no technology can work outside the laboratory. Facts have proved that it is very difficult to produce thin-film solar cells

in 2005, the first solar energy company entered the solar energy market with a cadmium telluride thin film battery. Their production costs have fallen rapidly, and they have also won contracts worth billions of dollars. Just two days ago, they also signed a 2billion watt contract with Chinese officials. Investors now believe that the market value of first solar is higher than that of American Airlines, Delta Airlines and federal Airlines combined. The first solar energy company has become the biggest obstacle and goal of nano solar energy company

the biggest difference between Nano solar and other companies is that their technology of bonding semiconductors to metal foil is very special. Most companies need to operate in a vacuum environment, and nano solar can directly print solar cells on metal foil

the difference between them and other companies is that they have invented a technology that does not require a vacuum environment to produce solar panels. Migcantea, a thin-film solar researcher at the National Renewable Energy Laboratory, said. It seems common that there are strict rules for sample preparation and experimental methods. I want to point out that this wet chemical technology can save a lot of money for its investment in fixed equipment

this kind of solar cell's base plate aluminum foil is large in quantity and cheap, which is the company's advantage in raw materials and production

earlier this year, first solar announced that they began to produce solar cells with a price of less than $1 per watt. Nano Solar said their price could be lower. Nano also took the first solar energy company as the following knowledge in the recent white paper, and claimed that their system balance cost (all other raw materials except the solar panel itself) was lower

for a company that has not yet been put into commercial production, it seems to be talking big, but nano company has $500million in venture capital and some cutting-edge technologies. In addition to the contract they have won, they also announced that the national renewable energy laboratory test confirmed that nano's battery is the most efficient printed solar cell, with a conversion rate of 16.4%

even if the competition among solar energy companies is heating up, there is still a lot of market space in the expanding renewable energy market. Market competition can promote technological progress and reduce production costs, which is good news for solar advocates. Since the main cost of solar energy production was reduced in the early 1990s, the average cost of solar modules has not been significantly reduced

if companies like first solar and nano solar continue to grow, they will reduce the average price of solar energy to compete with fossil fuel tanks. First solar will produce one billion watts of solar panels this year. The output of nano company is relatively small. They have equipment that can produce 640 megawatt battery panels, and the output will gradually increase from the current 1 megawatt per month. Using pervaporation to expand production may encounter some difficulties, but rothcheson is very confident

there are still many things to be done before it is put into production. Unless all the problems are solved, it is impossible to produce onemillion batteries per month. He said that this is also why our production personnel believe that the process from 0 to 1 MW is more challenging than the expansion from 1 MW to 100 MW
