Energy shortage has become a major obstacle to the current economic development,and is the focus of all countries in the world.As the source of a clean and renewable energy,solar cells are receiving more and more attention.It is of great significance to solve the energy crisis.Through the literature co-citation,TF * IDF and LLR algorithms as well as clustering analysis method,this article has analyzed the citation data and subject data of highly cited papers in the solar cell research field,identified the important academic papers,and then used the information visualization analysis software CiteSpace,and provided knowledge mapping analysis of five themes of solar cells research.The results show that high energy conversion of perovskite solar cell is the research frontier in the field of solar cell research.After further research on the clusters of intellectual base and the citing papers of research front,the research on the improvement of perovskite materials,hole transport materials,as well as the equipment and process for material preparation are summerived to develop perovskite solar cells with high conversion and low lost.The paper may offer the clues of decision-making and reference for domestic researchers to follow and to occupy the highland of the world's development frontier in the field of solar cell.%能源短缺已经成为阻碍当前经济发展的重要问题之一,是世界各国关注的焦点.太阳能电池作为一种清洁可再生能源正受到越来越多的关注,对解决能源危机具有重要意义.通过文献共被引、TF* IDF和LLR算法以及聚类分析等方法,对太阳能电池研究领域高被引论文引文数据和主题词数据进行分析和处理,梳理了太阳能电池研究领域重要的学术论文,并采用信息可视化分析软件CiteSpace,以知识图谱的方式展示太阳能电池领域5个研究主题结果表明,高能量转化效率的钙钛矿太阳能电池是当前太阳能电池研究领域的研究前沿.进一步对图谱聚类的知识基础和反映研究前沿的施引文献分析发现,围绕着研究前沿展开的研究主要包括钙钛矿吸光材料、空穴传输材料和钙钛矿制备工艺等3方面,以期开发制备高转化效率低成本的钙钛矿太阳能电池研究结果可能有助于我国科研人员迅速了解太阳能电池的最新研究发展方向并取得进一步突破,同时为我国跟踪和占领世界太阳能电池技术制高点提供了可供决策参考的线索.
