摘要:

能源短缺已經成為阻礙當前經濟發展的重要問題之一，是世界各國關注的焦點。太陽能電池作為一種清潔可再生能源正受到越來越多的關注，對解決能源危機具有重要意義。通過文獻共被引、TF*IDF和LLR算法以及聚類分析等方法，對太陽能電池研究領域高被引論文引文數據和主題詞數據進行分析和處理，梳理了太陽能電池研究領域重要的學術論文，并采用信息可視化分析軟件CiteSpace，以知識圖譜的方式展示太陽能電池領域5個研究主題。結果表明，高能量轉化效率的鈣鈦礦太陽能電池是當前太陽能電池研究領域的研究前沿。進一步對圖譜聚類的知識基礎和反映研究前沿的施引文獻分析發現，圍繞著研究前沿展開的研究主要包括鈣鈦礦吸光材料、空穴傳輸材料和鈣鈦礦制備工藝等3方面，以期開發制備高轉化效率低成本的鈣鈦礦太陽能電池。研究結果可能有助于我國科研人員迅速了解太陽能電池的最新研究發展方向并取得進一步突破，同時為我國跟蹤和占領世界太陽能電池技術制高點提供了可供決策參考的線索。

Abstract:

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.
