随着碳中和目标的逐步推进，未来太阳能发电在电力供应中的占比将大幅增加。到2050年，太阳能发电将占全球发电量的50%左右。这可能是未来光伏多样化应用并融入我们日常生活的转折点。柔性太阳电池技术是光伏的下一个前沿领域，是实现碳中和的关键途径。光伏技术与其他领域的融合将大大拓宽光伏产业的发展空间，赋予产品或领域更高的附加值。
近日，中国科学院上海微系统与信息技术研究所刘正新研究员、刘文柱研究员、西南石油大学俞健副研究员和常州大学宋欣教授等人在Science China Materials发表综述论文，综述了柔性太阳电池（钙钛矿太阳电池、有机太阳电池、柔性硅太阳电池）的最新研究进展，并对柔性太阳电池技术的未来应用进行了展望。
