Since 1954 photovoltaics (PV) has moved from a negligible contribution in the energy supply to a significant level (12.1% of electricity in Germany in April 2018 for example), mostly based on silicon wafer technologies and representing about 415 GWp installed in the world. To reach the multi TW scale, disruptive scientific innovations are needed in addition to incremental improvements of present technologies and concepts. Increasing the conversion efficiencies beyond the Shockley-Queisser-Limit by innovative concepts or architectures such as multijunctions, reducing the cost of production by innovative technologies and processes, reducing the carbon footprint and grey energy by low cost and abundant materials and finally driving down the electricity costs from PV to a few eurocents per kWh, are exciting challenges for all researchers worldwide. A key point of the development of disruptive PV is that it involves at an unperceived level chemical sciences and concepts. Developing next generations of photovoltaic devices at the multiTW scale is thus a Grand Chemical Challenge. The symposium will serve as an active platform for researchers to bring into light the state of the art and new contributions of chemistry in the field of disruptive photovoltaics that can reach TW of installed power.
