Tutorial 1Crystalline silicon solar cells: state-of-the-art and industry trends
Crystalline Silicon Solar cells: The State of the Art and Industry Trends In the global photovoltaic market, crystalline silicon currently has a market share of more than 90%. However, there is not “a single c-Si technology”. Instead, the market is divided between multi- and mono-crystalline silicon, and to a lesser degree between p- and n-type substrates. In addition, there exists a variety of different solar cell architectures and a myriad different processing technologies. The initial aim of this tutorial is to establish a basic understanding of the operating principles of a crystalline silicon solar cell and the interaction between its components (i.e. wafer bulk, surfaces, metal contacts). Based on this knowledge, the current mainstream solar cell type (p-Si wafer with full-area Al contact on the rear side) and its fabrication will be discussed. We will then consider recent advancements in mainstream technologies (e.g. screen printing) as well as advanced solar cell types already in production (PERC, HJ, IBC). Finally, we will take a look at alternative processing technologies (such as ion implantation), latest research results, and development trends.

Tutorial conductor: Dr Bianca LIM, SERIS
Bianca Lim studied physics at Freie Universität Berlin, Germany, and did her Diploma thesis at Hahn-Meitner-Institut, Berlin. Afterwards, she joined the Institute for Solar Energy Research Hamelin (ISFH) for a doctorate about boron-oxygen-related recombination centers in silicon, receiving a PhD (Dr. rer. nat.) from Leibniz Universität Hannover in 2011. Afterwards, she led a project at ISFH, working on simplified processes for local doping and n-type PERT silicon solar cells. Since 2016, she is with the Solar Energy Research Institute of Singapore (SERIS), working on all-back-contact solar cells as well as ion implantation.
