Researchers at King Abdullah University of Science and Technology (KAUST) have developed a new type of solar cell that has the potential to significantly improve the energy efficiency of renewable energy sources.

The government of Qatar's policy support and local advanced technology infrastructure willcreate a US $75 billion investment opportunity in the clean technology industry, Qatar's GulfTimes reported recently, citing a report from the Qatar Investment Promotion Agency.

At present, the large-scale industrialized secondary batteries mainly include lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries and lithium-ion batteries. Cadmium-nickel batteries contain the highly toxic element cadmium, which has been gradually replaced by other batteries. At present, the most widely used batteries on the market are lead-acid batteries, lithium-ion batteries and nickel-hydrogen batteries.

The advantages of lithium-ion batteries are of large capacity and high operating voltage. The battery capacity is twice that of an equivalent nickel-cadmium battery, making it more suitable for long-term communications. The traditional lithium-ion battery voltage is 3.7v, which is three times the voltage of nickel-cadmium batteries and nickel-hydrogen batteries.

Ultra-long life, the cycle life of long-life lead-acid batteries is about 300 times, and the maximum is 500 times, while the lithium iron phosphate power battery produced by Guangzhou Fengjiang Battery New Technology Co., Ltd. has a cycle life of more than 2,000 times. Standard charging (5 hours rate) use, can reach 2000 times.

The production process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells is much lower. In terms of production cost

Among the silicon series solar cells, monocrystalline silicon large solar cells have the highest conversion efficiency and the most mature technology. High-performance monocrystalline silicon cells are based on high-quality monocrystalline silicon materials and related thermal processing techniques.

Reliable Quality Positive power tolerance:0~+5W Modules binned by current to improve system performance Improved material to allow modules to operate reliable in multiple mounting configuration

Panama National Energy Secretary Rivera said that the promotion of photovoltaic technology will help Panama achieve energy independence and energy security. Relevant government departments will jointly implement incentive policies to further simplify the application procedures for the installation of solar power generation equipment, and promote relevant project financing and technology research and development.

The completion of the Garissa photovoltaic power station has effectively alleviated the electricity shortage in Kenya, and clean energy is contributing to the sustainable development of the local economy.
