Based on a recent discovery of the giant refractive index modulation associated with graphene oxide to graphene transition upon laser exposure and the breakthrough of graphene silicon solar cells. This project aims to investigate a new concept of an integratible, broadband, dispersionless, ultraflat lens array from nanostructured graphene oxide/graphene. This conceptually new development of functional graphene oxide/graphene lens array in combination with a lumpy nanoparticle enabled back light trapping layer will allow for the non-reciprocal coupling of the broadband solar light into the photovoltaic devices with minimised entropy losses. Thus ultrahigh efficiency solar cells exceeding the conventional theoretical limit can be developed.

基于最近发现的与氧化石墨烯在激光照射下向石墨烯转变相关的巨大折射率调制以及石墨烯硅太阳能电池的突破。该项目旨在研究由纳米结构氧化石墨烯/石墨烯制成的可集成、宽带、无色散、超平透镜阵列的新概念。功能性氧化石墨烯/石墨烯透镜阵列与发光纳米颗粒使能的背光捕获层的这种概念上的新发展将允许宽带太阳光以最小化的熵损失非互易耦合到光伏器件中。因此，可以开发出超过传统理论极限的高效率太阳能电池。
