Chinese Academy of Sciences Yu Tingyun today revealed at the "2012 First China-Hainan Green Development Forum" that Chinese scientists are developing biological solar cells. “How to make efficient use of solar energy is a commanding height in the international academic community. Scientists in developed countries such as the United States and the European Union are working hard to see who can make the first breakthrough.†This forum is organized by China Biodiversity Conservation and Green Development Foundation, China. The Ecological Society, the China Association of Older University and Haikou Municipal Government jointly sponsored. "Because of the global changes and the exhaustion of energy caused by the large-scale use of fossil energy, as well as the need for sustainable development and protection of the environment, the world has begun to focus on renewable energy sources, including biomass energy," said Yan Tingyun. Yan Tingyun said that the conversion and utilization of solar energy for leaves has reached almost 100%. How to artificially simulate the photosynthesis process and capture and use solar energy has become the focus and focus of scientists' research. According to the forecast of the European Union Research Center, "solar fuel" will gradually replace traditional fossil fuels - by 2020, "solar fuel" will account for 1% of the energy structure, by 2450 by 2450, and by 2100 it will reach 64%. "The use of solar energy has broad prospects, but the key to the problem is how to effectively use solar energy." Yan Tingyun said. The development of solar cells has gone through several stages such as crystalline silicon cells and thin-film batteries. The problem of crystalline silicon cells is high cost and pollution. The problem of thin-film cells is low conversion rate. Yan Tingyun and her team selected bio-solar batteries. Yu Tingyun said: “We are conducting related research and hope to build solar cells for biological/organic hybrid materials, which will greatly increase the photoelectric conversion rate through solar energy captured by photosynthesis membrane proteins.†(Reporter Qi Fang)
Tension and compression load cells can be used to measure both tensile and compressive loads. Manufactured from stainless steel or aluminium alloy, these tension and compression load cells offer a high level of corrosive resistance for use in harsh environments with environmental sealing up to IP68. Available in capacities from 1kg to over 100 tonnes, all tension and compression load cells are supplied with a full certificate of calibration. Custom designed tension and compression load cells are also available, along with a wide variety of associated instrumentation.
