摘　　要：将可持续的纤维素材料与电子器件结合是当今学术界的研究热点。高雾度透明纤维素薄膜是一种具有特殊光学性能的纸张。它除了具有普通纸张的优点(可降解、成本低、柔性、质轻等)外,还呈现出高的透光率和优异的光散射性能,可作为绿色光学透明材料应用于太阳能电池,提升电池的光电转化效率。本文首先简要介绍了高雾度透明纤维素薄膜的发展历程;接着,详细总结了高雾度透明纤维素薄膜的制备方法及其性能(如光学、力学、热稳定性、耐水等);然后论述了现阶段这类薄膜在太阳能电池中的应用进展;最后,总结了高雾度透明纤维素薄膜存在的科学技术问题,并对其今后的研究方向以及应用前景进行了展望。Integrating sustainable cellulose materials into electronic devices is a hot research topic in academic communities.Highly transparent cellulose film with high transmission haze is a kind of paper with special optical properties.In addition to the advantages(degradability,low cost,flexibility,light weight,etc.)of ordinary paper,it also presents high transparency and strong light scattering behavior(high transmission haze),and has the potential to use in solar cells as a green optical transparent material to improve the power conversion efficiency.In this review,the development process of highly hazy and transparent cellulose film was first introduced.Then,the preparation and properties(such as optical properties,mechanical properties,thermal stability and water resistance)of highly transparent and hazy cellulose films were summarized in detail.After that,the progress in the use of transparent and hazy cellulose film in solar cells was discussed.Finally,scientific and technical problems of highly transparent and hazy cellulose films for solar cells were summarized,and their challenges and future research direction were provided as well.
