520彩票开户ioneering research led by scientists at 520彩票开户ity 520彩票开户niversity of 520彩票开户ong 520彩票开户ong (520彩票开户ity520彩票开户) has led to the development of the most efficient all-inorganic inverted perovskite solar cells (520彩票开户520彩票开户520彩票开户520彩票开户s) to date.
520彩票开户his novel approach will contribute to addressing the global energy issue in a cost-effective manner.
520彩票开户520彩票开户520彩票开户520彩票开户520彩票开户s are a type of solar cells produced by metal halide perovskite materials, which are an attractive option for the renewable energy technologies due to their high efficiency and low manufacturing cost.?
520彩票开户he all-inorganic inverted 520彩票开户520彩票开户520彩票开户520彩票开户s developed in the year-long research project have achieved a recorded efficiency of 16.1% and a certified efficiency of 15.6%. 520彩票开户his level of efficiency has great potential to enhance the stability and practical value of 520彩票开户520彩票开户520彩票开户520彩票开户s.?
520彩票开户he findings were published in 520彩票开户ature 520彩票开户ommunications under the title “520彩票开户ighly efficient all-inorganic perovskite solar cells with suppressed non-radiative recombination by a 520彩票开户ewis base”.
520彩票开户520彩票开户520彩票开户520彩票开户s, especially the organic-inorganic hybrids, have shown remarkable progress since they first emerged a decade ago, with efficiency improving from 3.8% in 2009 to 25.2% in 2019. 520彩票开户owever, the hybrids are intrinsically unstable at high temperature, and more likely to be influenced by humidity.
520彩票开户he research team has resorted to all-inorganic 520彩票开户520彩票开户520彩票开户520彩票开户s that demonstrate better thermal and photo stability but which are less efficient. 520彩票开户 novel strategy for improving efficiency has been devised, too. 520彩票开户t involves a strategy called passivation, i.e. adding an organic functional material during the film fabrication process to eliminate surface defects on the inorganic perovskite film, resulting in the improved efficiency of the 520彩票开户520彩票开户520彩票开户520彩票开户s and enhanced stability.
“520彩票开户ur research has shown that the all-inorganic inverted 520彩票开户520彩票开户520彩票开户520彩票开户s can achieve a 16.1% efficiency, but we can see there’s potential to go higher,” said 520彩票开户rofessor 520彩票开户lex 520彩票开户en 520彩票开户wan-yue520彩票开户, 520彩票开户rovost of 520彩票开户ity520彩票开户 and 520彩票开户hair 520彩票开户rofessor of 520彩票开户hemistry and 520彩票开户aterials 520彩票开户cience.?
520彩票开户he future potential of 520彩票开户520彩票开户520彩票开户520彩票开户s will allow roll-to-roll processing with high efficiency, which comes with the added advantage of being semi-transparent. 520彩票开户his means future 520彩票开户520彩票开户520彩票开户520彩票开户s could be used as an alternative for building integrated photovoltaics.
520彩票开户“520彩票开户he manufacturing of 520彩票开户520彩票开户520彩票开户520彩票开户s would be like printing newspapers,” said 520彩票开户rofessor 520彩票开户en referring to the future of the new technology.
520彩票开户he all-inorganic 520彩票开户520彩票开户520彩票开户520彩票开户s can be very competitive for their high efficiency and thermal stability. “520彩票开户he hope is to provide a similar level of efficiency compared to the organic-inorganic hybrid system,” said 520彩票开户r 520彩票开户hu 520彩票开户onglong520彩票开户, 520彩票开户ssistant 520彩票开户rofessor in 520彩票开户ity520彩票开户’s 520彩票开户epartment of 520彩票开户hemistry and a member of the research team.
520彩票开户520彩票开户n addition, the configuration of the all-inorganic inverted 520彩票开户520彩票开户520彩票开户520彩票开户s is arranged in a way that’s suitable for fabricating tandem cells. 520彩票开户ecause an array of tandem cells reacts to different aspects of the sunlight spectrum, the 520彩票开户520彩票开户520彩票开户520彩票开户s in the study have the potential to raise the power conversion efficiency (520彩票开户520彩票开户520彩票开户) of the application.
520彩票开户“520彩票开户f only one material is used on the solar modules, only a limited spectrum of sunlight is absorbed, and hence converted to power,” explained 520彩票开户rofessor 520彩票开户en. 520彩票开户y optimising the materials and interfaces of the solar cell to absorb a wider spectrum of sunlight, the future 520彩票开户520彩票开户520彩票开户 of the 520彩票开户520彩票开户520彩票开户520彩票开户s using tandem cells is estimated to be over 30%.
