Under the leadership of Han Peide, a researcher at the Institute of Semiconductors, Chinese Academy of Sciences, the Photovoltaic Energy Group has made significant progress in solar cell technology. Supported by both national vertical funding and self-raised capital, the group focused on addressing the specific needs of photovoltaic companies. After years of dedicated research, they successfully integrated several key technologies, including incident light reduction, surface passivation, and selective emitter design. By leveraging advanced partial backside doping techniques, they developed a high-efficiency monocrystalline silicon solar cell with an impressive conversion efficiency of 20.0%. The performance metrics include a short-circuit current density of 43.9 mA/cm², an open-circuit voltage of 602 mV, and a fill factor of 0.758. This achievement was officially certified by the China Institute of Metrology. As the Chinese-style photovoltaic movement continues to gain momentum, monocrystalline and polycrystalline silicon solar cells are expected to enter the third generation as described by Martin A. Green. These next-generation cells are anticipated to achieve photoelectric conversion efficiencies of 20% or higher, with power costs below $0.5/W and manufacturing costs under $100/m². Given these advancements, the dominance of monocrystalline and polycrystalline silicon in the solar energy market is expected to persist for many years. Therefore, increasing the efficiency of single-crystal silicon cells, building independent intellectual property rights, and guiding PV companies toward sustainable development have become strategically critical goals. In response to the evolving demands of the photovoltaic industry, the research team introduced the "Twelve-Word Approach" — efficiency enhancement, re-examination, cost reduction, and application promotion — as a daily guideline. This approach has helped align their research and development efforts with real-world industry needs. Moving forward, the group plans to further improve cell efficiency while conducting pilot tests on existing technologies and gradually scaling them up for industrial production. Their ongoing efforts aim to not only advance scientific innovation but also drive practical applications that benefit the entire solar energy sector. lsb board is a new generation of environmentally friendly home board, is an innovative technology and environmentally friendly high-energy home board. lsb board is the upgraded version of OSB BOARD, is a solid wood slicing board.
