空间航天器需要高效稳定的电源供应,但同时受限于运载火箭运输能力的限制,对电源质量有严格的要求,因此高效轻量化太阳电池是未来空间电源主要的发展方向,成为当前国内外空间电源研究的重点。分析了高效轻量化太阳电池的专利申请趋势,梳理出高效轻量化太阳电池专利申请的地域分布和全球主要专利申请人,通过对主要专利申请人的专利布局进行分析,指导相关研究单位有效进行专利布局,避免产生专利纠纷,降低研发过程中的专利侵权风险;同时通过技术发展路线寻求重点研发方向的技术创新。
Space spacecrafts require highly efficient and stable power supply,but at the same time is limited by the transport capacity of the launch vehicle,and has strict requirements on the weight of the power source.Therefore,efficient and lightweight solar cells are the main development direction of future space power sources,becoming the focus of space power research all over the world.The patent application trend of high-efficiency and light-weight solar cells were analyzed,and the geographical distribution of high-efficiency and light-weight solar cell patent applications and major global patent applicants were sorted out.By analyzing the patent layout of the main patent applicants,guidance was provided.And by analyzing the patent layout of relevant research units carrying out effectively,to avoid patent disputes,and to reduce the risk of patent infringement in the research and development process.Meanwhile,the technical innovation in key research and development directions were seeked through technical route analysis.
