Cellulose nanopaper (CNP) has attracted much interest during the last decade as a new fascinating renewable and biodegradable substrate for printed electronics and solar cells. Its outstanding optical and mechanical properties make CNP the ideal substrate for the preparation of photovoltaic devices, since its high transparency and haze favour the absorption of light from the active layer of the solar cell. However, some advances need to be done in the direction of increasing CNP stability in humid environment without compromising its remarkable advantages. This review critically points at these aspects, presenting an overview of state-of-art solutions to enhance nanopaper stability in a humid environment.

用于透明光收集装置的可再生和可生物降解纤维素纳米纸基材的最新进展：与潮湿环境的相互作用

在过去的十年中，纤维素纳米纸 (CNP) 作为一种用于印刷电子产品和太阳能电池的新型可再生和可生物降解基材，引起了人们的极大兴趣。其出色的光学和机械性能使 CNP 成为制备光伏器件的理想基材，因为其高透明度和雾度有利于吸收来自太阳能电池活性层的光。然而，在不损害其显着优势的情况下，需要在提高 CNP 在潮湿环境中的稳定性的方向上取得一些进展。这篇综述批判性地指出了这些方面，概述了在潮湿环境中增强纳米纸稳定性的最新解决方案。
