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.Read moreRead less

Summary
Molecules and mirrors: new directions in chemistry and organic optoelectronics using hybrid light or matter states. This project will explore the exotic mixtures of light and matter that can form when molecules are placed in nano-scale mirror cavities. If the chemical reactivity of these mixed light or matter states can be controlled, a new generation of efficient, organic solar energy capture and storage devices is anticipated.
Photonic crystals at visible wavelengths. Three dimensional sculptured nano-structures made at a very high spatial resolution will open way to control light emission, propagation, and transmission at the visible wavelengths. Optically thin and transparent solar cells will be able to harvest light using structures.

The project seeks to develop high performance photoferroelectric materials for a wide range of photoenergy conversion technologies like photovoltaics and photocatalytics. For the past 50 years, ferroelectric photovoltaics have only been an academic curiosity due to their low energy conversion efficiency relative to the popular semiconductor photovoltaics. This project aims to unlock the potential of ferroelectric photovoltaics by introducing an ion co-substitution, which is coupled with electron-pinning, into promising ferroelectric materials and investigating the resultant photo-excited electronic and electrical properties. It is anticipated that the outcomes from this proposed project will provide a solution for optimal ferroelectric visible light absorption to achieve high power conversion efficiency in ferroelectric materials for practical photoenergy applications.Read moreRead less
