Tandem Cells: The next big thing in Photovoltaics?

Solar Photovoltaics has become arguably the cheapest method ever to generate electricity. The story of the development of photovoltaics over the last three decades is an incredible success story - and one that could not be more timely given the need to urgently reduce greenhouse gas emissions. However, the necessary rapid electrification of nearly everything - including transport and industrial processes - demands even cheaper electricity. One way that photovoltaics may be able to deliver on this requirement is through tandem solar cells that promise higher efficiencies and, hopefully, lower costs. Tandem cells combining cells based on perovskite and silicon materials seem especially promising - but perovskite cells pose many tough challenges for research and industry. In this talk, we will discuss some of these challenges and take a peek at possible ways of addressing them.

Klaus received his undergraduate degree in Electrical Engineering from the University of Adelaide and a PhD in Engineering from the ANU. He has spent the last 28 years researching various aspects of photovoltaics. His initial research focused on silicon and the development of new methods to fabricate silicon solar cells. He is the co-inventor of several technologies including Sliver technology (note: Sliver not Silver!) which was bought by Origin Energy and became the subject of a $240m commercialisation effort. In 2014, together with Prof Kylie Catchpole and A/Prof Tom White he established the perovskite research group at ANU. The group has set several efficiency records over the last few years including for perovskite-silicon tandem cells and has made some significant contributions to better understanding the physics of perovskite cells. He is the recipient of several awards including the Banksia Award, the Australian Institute of Energy Innovation in Energy Science & Engineering Award and the Australian Institute of Physics Alan Walsh Medal.
