At the 41st International Invention Fair in Geneva, a groundbreaking solar energy system developed through a collaboration between Hubei University of Technology and Kunwei Energy was awarded a Special Gold Award. This prestigious recognition highlights the success of school-enterprise cooperation in advancing renewable energy technology.
The "Concentrating Solar Roof System," co-developed by Optics Valley Cove Energy and Hubei University of Technology, stood out among other entries and received one of only three Special Gold Awards. On April 18, a reporter had the opportunity to meet with the system’s founder and view the exhibition at Hubei University of Technology.
In May of last year, the Ministry of Science and Technology released the "12th Five-Year Plan for the Development of Solar Power Technology." The plan positions Concentrating Photovoltaic (CPV) Technology as the third generation of photovoltaic systems, following crystalline silicon and thin-film technologies.
The company behind the innovation has a core team of nine members, including experts from the "3551 Optical Valley Talent Plan." It is currently the only company in Hubei Province that comprehensively masters CPV technology. Leveraging the research capabilities of Hubei University of Technology and other institutions, the team spent over three years developing an independent, high-performance concentrating photovoltaic roof system—from battery modules to the entire solar energy system.
A prototype of the concentrating roof solar power system is displayed above. Lu Hui, general manager of Wuhan Bosun Energy Technology Co., Ltd. and associate professor at Hubei University of Technology, explained that this technology differs from traditional solar cells. Instead of using standard panels, it employs plane Fresnel lenses to focus sunlight onto a new type of photovoltaic material: multi-junction gallium arsenide cells. These cells are just 1/1000 the size of conventional crystalline silicon cells but generate twice the power.
The system achieves a 44% sunlight utilization rate, with a final conversion efficiency of 31%, significantly higher than the typical 20% of traditional photovoltaic materials. The demonstration model installed on the university's rooftop covers six square meters and produces 1,000 watt-hours of electricity. Compared to conventional systems, this CPV system requires half the space and offers lower costs, making it ideal for urban buildings with limited roof space.
Lu Hui also noted that the company has filed six invention patents. The prototype addresses previous issues with top-heavy concentrating systems by using a polar axis tracking method. The system moves only once a day in the north-south direction, with minimal adjustment, and uses a linkage drive in the east-west direction. This design reduces the system's weight, height, and center of gravity, making it more efficient and practical.
Li Ziqiang, dean of the School of Science at Hubei University of Technology, mentioned that the university and the company have established a Photovoltaic Engineering Application Research Center. They are also in discussions to join the Hugong University Science and Technology Industrial Park, aiming to turn this project into a key example of the industrialization of academic research achievements.
