中文摘要: |
2021年全国两会期间,碳达峰、碳中和成为热词,各界呼吁加快新能源技术发展与推广。近几年,钙钛矿太阳电池(PSC)作为一种新兴的太阳能技术受到了广泛关注。本文以德温特创新索引数据库为基础,利用专利分析方法从时间分布、地理分布、专利权人分布和技术分布等方面对PSC专利进行研究。结果表明,2013年起PSC专利申请数量加速上升,进入成长期;PSC技术主要来源国家有中国、美国、韩国和日本等,专利受理较为活跃的地区有美国、中国和欧洲等;中国专利申请以科研机构和新能源企业为主,韩国以科研机构为主导,日本以大企业为主导,其他国家和地区专利申请人较为分散;PSC研发热点包括太阳电池电极、半导体材料和关键加工工艺等。 |
英文摘要: |
Based on the patents data of perovskite solar cells (PSC) in the Derwent innovations index (DII), this paper discusses development of PSC through patent analysis from the aspects of time distribution, geographical distribution, patentee distribution and technology distribution. The results are as follows:the number of PSC patents has accelerated since 2013; the main source countries of PSC technology are China, US, Korea and Japan; most Chinese patentees are academic or research institutions and new energy enterprises, most Korean patentees are scientific research institutions while most Japanese patentees are large enterprises; PSC research focuses on cell electrodes, semiconductor materials and key processing technology. |
