摘　　要：利用专利计量分析方法考察太阳能电池材料领域的全球专利竞争趋势情况,对中国太阳能电池R&D策略具有重要参考意义。分析结果显示中国在该领域的专利申请总量上排在世界第三位,增长势头十分强劲。然而中国的创新主体数量却明显不足,专利权人主体结构不够优化,尤其在国外的专利申请量极少,专利布局存在严重的结构失衡。The method of patentometric is used to examine the global competitive trend of solar cell materials, which is of great importance to advise the R＆D policy in this field of China. The results of studies show that in this field, China ranked third in the world in total amount of patents with rapid progress. But the number of inventors and intornational patants are much less than the number of other countries. The structure of inventors should also be improved because of larger portion of patents application coming from universities than companies.
