German thin solar cell technology was a breakthrough comparable to silicon cells

German researchers in improving the coating technology, the IEC-thin solar cell conversion efficiency of 20.1% energy, had crystalline silicon solar cells can be comparable.

Stuttgart, Germany “Solar - Hydrogen Research Centre” Researchers have developed a copper, indium, gallium and selenium oxide in high-efficiency solar cells (called CIGS-CIS-cell or battery).laptop battery  This battery has 20.1% of solar energy - the efficiency of converting electricity, efficiency is the world’s highest conversion of thin solar cells. It is a narrow margin two years ago , the United States, “National Renewable Energy Laboratory,” the invention of the same type of solar cells.

Comparable with silicon cells

cells of crystalline silicon solar-CIS with fewer materials used, low cost, the latter due to the need to use a certain purity crystalline silicon is made of high cost. Despite the low cost of amorphous silicon thin film solar cells, but before the energy conversion rate of less than 7%. Stuttgart Research Centre of the battery is only 0.5 square cm surface area, the thickness of just 4 / 1000 mm, consists of four solar rays into electricity photosensitive layer. Stuttgart researchers used a thin coating technology allows efficient conversion rates Solar energy reached record levels across the chemical industry for the production of these batteries possible.

Solar energy will be higher profit margins

With the conversion efficiency of thin solar cells, photovoltaic production equipment to produce electricity and profit margins will be significantly improved. Dell Latitude E6400 battery , Currently on the market the most common CIS-CI half the energy conversion and crystal silicon integrated circuits almost half were 10% to 12%. (Semiconductor integrated circuits a single conversion efficiency of solar cells is lower.) Researchers from Stuttgart, said the coming years, CIGS solar-energy conversion devices will increase to 15%.
