Double side contacted cells with innovative carrier-selective contacts

ended

The DISC project addresses the need to reduce the consumption of fossil fuels by developing key technologies for the next generation of high-performance photovoltaic (PV) solar cells and modules, allowing ultra-low solar electricity costs with minimum environmental impact. DISC focuses on the only way to fully exploit the potential of silicon to its maximum: through the use of carrier selective junctions, i.e., contacts which allow charge carriers to be extracted without recombination. Such contacts allow for simple device architecture as considered in DISC - non-patterned double-side contacted cells – which can be fabricated within a lean process flow, either by upgrading existing or within future production lines. In DISC, a unique consortium of experienced industrial actors will collaborate with a set of institutes with demonstrated record devices and worldwide exceptional experience in the R&D field of carrier selective contacts. DISC will target efficiencies >25.5% on large area cell and >22% at module level while demonstrating pilot manufacturing readiness at competitive costs. Together with a reduction of non-abundant material consumption (Ag, In), with an enhancement of the energy yield, with modern module design ensuring outstanding durability, DISC will provide the key elements for achieving in Europe very low Levelized Costs of Electricity between 0.04 – 0.07$/kWh (depending on the irradiation), with mid-term potential for further reduction, making solar one of the cheapest electricity source. The high efficient PV modules developed in DISC are predestined for rooftop installations, i.e., neutral with respect to land use aspects. A life cycle approach applied in DISC prevents the shifting of environmental or social burdens between impact categories. DISC has a chance to contribute towards mitigating the impacts of climate change, improving energy access and towards bringing Europe back at the forefront of solar cell science, technology and manufacturing
