To improve the efficiency of thin-film solar cells, from Germany, Switzerland, France, Italy, Belgium, Luxembourg and other European eight countries 11 scientific research team last year formed a research alliance, and announced the implementation of "Sharc25" program, the purpose is to CIGS thin film solar cells Conversion efficiency from the current 21.7% to 25%. They hope that the next few years, solar cells can be used for wearing electronic and other small devices, but the biggest goal is for buildings and solar energy and other public utilities large-scale power generation. "If this goal can be achieved, the performance of European solar cells can get a qualitative leap, will remain in the global market dominance." Germany "solar cell" magazine also quoted experts as saying that thin film solar cells are widely used, Contribute to the rapid decline in the cost of solar power, the next 15 years, it is expected to become the cheapest energy.
However, to make thin film solar really into people's lives, improve people's awareness, but also need to rely on both creative and practical products. In 2015, the Dutch HolstCenter Center (HolstCenter) with a Dutch fashion designer jointly launched a solar shirt. 120 thin film solar cells sewn on clothes, people can wear it in the sun can be power, you can in a few hours for an iPhone full of electricity, but also to the camera, MP3 player, GPS and other devices using USB interface Provide electricity, or store electricity for night use. Moreover, this product can also be the same as ordinary clothes cleaning.
According to "Japan Economic News" reported that Tokyo, a company called "system TOOKYSU" company developed a solar ultra-thin charger, 90 minutes to complete the iPhone charge, the price of 5600 yen (about 361 yuan) The Japan's Mitsubishi Chemical announced last year that it will work with the United States to develop organic thin-film solar cells for listing within the year 2016. This product is translucent film-like, can be affixed to the office building glass window, the use of a period of at least 10 years, the price of about 10,000 to 20,000 yen per square meter, the company also tried to further reduce prices by mass production.
