New Solar Technology Power Generation Efficiency Hoisting Thin Film Solar Researchers at Purdue University in the United States have built a hybrid system that combines existing solar technologies to increase solar utilization efficiency to 50%. By utilizing the advantages of spectral splitting, the system improves solar light utilization efficiency, reduces power generation costs, and significantly improves grid compatibility. Ideally, the system will be able to utilize solar efficiencies in excess of 50% under existing conditions, while PV systems alone will have an efficiency of at most 31%.

Bio-solar cells: Moss can also generate electricity. Elena Mitrofanova, a student at the School of Advanced Architecture in Catalonia, Spain, proposed a moss-based photovoltaic system. In the process of photosynthesis, plants use light energy to convert carbon dioxide and water in the surrounding environment into organic compounds. "Organic compounds released by (moss) enter the soil containing commensal bacteria, which decompose organic compounds for survival, a process that produces by-products containing electrons.

Graphene + photovoltaic solar cells do not need to be used for rainy days. Engineers and materials scientists have done a lot to improve solar cell power generation efficiency and expand storage capacity. However, this solar power still needs the cooperation of the weather. When it comes to rain or cloudy weather, the power generation efficiency of solar cells is greatly reduced. Chinese scientists have successfully developed a new type of solar cell that can generate electricity in rainy days with the help of graphene.

The efficiency of developing tandem perovskite solar cells at Anglo American is expected to exceed 30%! Researchers at Stanford University and the University of Oxford in the United Kingdom have announced that tandem perovskite solar cells made by coating technology achieve high conversion efficiency of 20.3% and the battery has high durability. Conversion efficiency is expected to exceed 30% in the future. The paper has been published in the academic journal Science. The tandem solar cell is a technology that utilizes solar light more efficiently by two-layer solar cells to improve conversion efficiency.

The energy efficiency record of photovoltaic cells was once again broken by up to 34.5%. The University of New South Wales (UNSW) broke the energy efficiency record of photovoltaic cells and increased solar energy conversion efficiency to an astonishing 34.5%. Previously, Alta Devices in the United States had a record of 24% conversion rate, but UNSW's new equipment developed by senior researcher Mark Keevers and Martin Green of Australia's Advanced Optoelectronic Center has improved performance.

Fraunhofer concentrating photovoltaic module efficiency innovation up to 43.3%! After creating new solar cell efficiencies in 2014, Fraunhofer ISE announced that the efficiency of solar modules using concentrating photovoltaic (CPV) technology has once again set a new world record. According to the research institute in Freiburg, the new mini CPV module includes four-junction solar cells, which has a world record of 43.3%.

Multi-joined silicon solar cell efficiency exceeds 30%! The Fraunhofer Solar System Research Institute (ISE) in Germany collaborated with the Austrian company EV Group (EVG) to successfully convert silicon solar cell conversion efficiency based on silicon solar cells and multi-junction solar cell technology with two electrodes. To 30.2%.

Alta Devices' double-junction solar cell efficiency reached a record 31.6%. Alta Devices announced its world record for GaAs solar photovoltaics. The company produces double-junction cells with an efficiency of 31.6%. This latest technology has been awarded by the US Department of Energy. National Renewable Energy Laboratory (NREL) certification. In 2013, Alta's single-junction solar cell efficiency record reached 30.8%. Soon after, the record was overtaken by NREL, but Alta once again set a new world record.
