Next-generation solar cells
Thanks to global progress in research, photovoltaic systems will become increasingly efficient and their contribution to the global supply of energy will continue to rise, according to predictions by experts. The next goal of PV research is to further increase the efficiency and operating life of solar cells and to design and develop more cost-effective and sustainable production processes. Research at HZB is focussed on thin-film technologies and three-dimensional nanocomposite material topologies. Silicon, semiconducting compounds, and organic/inorganic hybrid structures are the base materials for this. Cost-effective, broad-coverage nanostructure technologies are being developed using top-down etching processes and shadow masks integrated with bottom-up self-organising processes. An additional object of research is to produce innovative electrode materials.
To create the prerequisites for a broad spectrum of innovations and thereby reduce the dependence PV has on a single technology.
