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

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
