Abstract
I will review our recent work on the use of nanopatterend metasurfaces to improve the performance of solar cells. Novel nanoscale light coupling and light trapping geometries improve thin-film CIGS cells and enable a large reduction in their thickness. I will introduce the concept of metagratings composed of resonant light scatterers forming a grating for improved light scattering in the ray optics limit. Metal nanowires serve as as transparent conductors and dielectric nanoscatters create colored or white photovoltaics using Si HIT cells. I will present progress on two ongoing collaborative projects between UNSW and AMOLF and present some ideas for potential future collaborations.

Brief Bio
Albert Polman is program leader of the “Light Management in New Photovoltaic Materials” program at the NWO Institute AMOLF in Amsterdam, the Netherlands and Professor of Photonic Materials for Photovoltaics at the University of Amsterdam. Polman's research group focuses on nanophotovoltaics, the study of light management at the nanoscale to realize solar cells with ultra-high efficiency that can be made at low costs.
Polman is an elected member of the Royal Netherlands Academy of Arts and Sciences (KNAW), Fellow of the MRS, OSA, and recipient of ERC Advanced Investigator Grants (2011, 2016), the EPS Research into the Science of Light Prize (2017), the Physica Prize of the Dutch Physical Society (2014), the Julius Springer Award for Applied Physics (2014), the ENI Renewable Energy Award (2012), and the MRS Materials Innovation and Characterization Award (2012). Polman is co-founder of Delmic BV, that brings on the market an instrument for angle-resolved cathodoluminescence spectroscopy developed in his group.
Polman is visiting Australia as part of the Frew Fellowship offered by the Australian Academy of Science.
