Recently, the “Cleantech” website has selected ten solar energy technologies worth noting. Although some of these technologies are still in trials, it is believed that these technologies will surely be applied in the near future!

1, water-cooled solar panels

Pyron Solar Triad designed a special short-focus, solar collector lens made of acrylic material. Sunlight reflects and refracts this type of lens to effectively concentrate energy to a point. The second lens captures the energy transmitted by the first lens and then focuses it on a small photovoltaic panel. The company claims that this HE lens system (HE OPTICS SYSYTEM) produces 800 times more power than an equivalent-sized silicon solar panel.

2. Convert solar energy to hydrogen

MIT professor Daniel Nocera founded a company that aims to commercialize a "water decomposition" and solar storage technology. Northell said: "Our idea is to use solar panels to provide electricity for the electrolyzer to produce hydrogen that can be stored in the fuel tank. When people need electricity, the stored hydrogen can drive the fuel cell to generate electricity. ."

3, solar roof panels and brushable solar panels

Previously, people had been thinking that if installing solar panels could be as simple as laying roof tiles, or that solar paint could be painted on the roof like a paint. In fact, this idea has already been realized and this kind of solar paint is called silicon ink. According to the US National Renewable Energy Laboratory, solar cells using this technology can already convert 18% of solar energy into electricity. Dow Chemical, on the other hand, said that by the middle of 2010, the solar roof tiles developed by the company will be capable of small-scale production and will be mass-produced in 2011.

4, large-scale thin film solar cells

SunFabTM system thin-film solar panels are mainly based on thin-film technology, using amorphous silicon solar panels to build the world's largest and most productive solar thin film panels. This approach can on the one hand successfully reduce the cost of materials, on the other hand it can also be combined with the most advanced manufacturing technology of the solar energy industry. It is reported that the company's thin-film solar panels are mainly frameless design, which solves the two major problems of thin-film solar panels with poor waterproof effect and long-term use will lead to the integrity of the panel structure is damaged.

5, organic solar collector

Scientists at the Massachusetts Institute of Technology have found a way to convert ordinary glass into high-end solar collectors. The technical structure is complex but the cost is low. Scientists mainly use coated glass plates to collect sunlight that has not been absorbed by the surface of solar cells, so that ordinary mirrors are converted into solar concentrators. Even the glass of buildings can be used to absorb and transform energy. In addition, GreenSun has also developed a solar panel that contains various colors that can collect light energy without directly aiming at the sun.

6, space solar energy technology

In the next 30 years, the device is expected to transmit solar energy to Earth on an orbit in space 36,000 kilometers away from Earth. The Japanese government will spend 21 billion U.S. dollars to support this plan, which mainly includes the construction of a solar power station with 4 square kilometers of solar panels. By then, the power station is expected to generate 1 billion watts of electricity, enough for nearly 300,000 households in Tokyo.

7. Solar Road

The idea of ​​solar roads is to develop a solar panel like a floor tile and lay it on the road. These panels are constantly capable of collecting light energy and generating electricity, but they can also be used for nighttime road lighting and winter warmth, while also allowing a large amount of surplus power to be sold to homes or businesses. Scott Brusaw, the inventor of this technology, estimates that solar panels per mile can provide power to 500 homes, and that each 12 x 12 foot panel costs only $5,000. .

8. Concentrated solar technology

The SunCatcher solar energy collection system developed by Stirling Energy System will soon settle in Arizona, which also marks the first time that the world's most efficient solar energy technology will be put into commercial use. The SunCatcher solar energy collection system consists of a solar concentrator and a curved glass mirror array arranged in a dish. The system is capable of collecting sunlight using a dish of glass mirrors and heating the efficient Stirling Engine, which produces 25,000 watts of power per dish.

9, nano-solar energy technology

Researchers at McMaster University in Ontario, Canada developed a light-absorbing nanowire using high-efficiency photovoltaic materials and durable carbon nanotube fibers, and implanted it into a tough polyester film to produce solar panel. This kind of solar panel is more flexible than current photovoltaic panels and has a lower cost. In addition, the research team of the Department of Physics and Astronomy from the University of Southampton in the United Kingdom has also been inspired by the photosynthesis of plants to produce a new photovoltaic device that can efficiently convert light energy into electricity.

10, integrated solar energy technology

The Andalay AC solar panel, developed by Akeena Solar, incorporates a variety of patented technologies such as the company's steel frame assembly, wiring assembly and electrical grounding assembly. Akeena Solar said that this approach can increase the stability of the system, thereby saving users thousands of dollars in maintenance costs over its 30-year design lifetime. Andalay AC solar panels can provide users with safe AC power, and the installation of solar panels is easier and safer, thanks to a 80% reduction in components and complicated and dangerous DC wiring. Andalay AC solar panel technology is hailed as the most popular mechanical invention in 2009.

In addition, there is a solar energy technology that cannot be ignored. It is a solar balloon developed by CoolEarth. This type of balloon is made of metal plastic film. Half of the balloon is transparent, which can facilitate the collection of light energy by efficient solar panels in the balloon. The diameter of the balloon is 8 feet. The scientists have also integrated the architectural tension structure theory into the design of the balloon. There is also a suspension system under the balloon to maintain its stability.
