AMPERE's common workshop

The Ampere project together with the NextBase and DISC projects presented the main results of the three projects in the workshop “High Efficiency Approaches in Crystalline Silicon PV"

AMPERE common workshop with sister projects.
Le Bourget du Lac. France. September, 25th. The Ampere project, together with its “sister” projects funded in H2020 NextBase and DISC, presented the main results of the three projects in the “High Efficiency Approaches in Crystalline Silicon PV” workshop.


The workshop, organized at the Polytech Annecy-Chambery, highlighted the path towards high efficiency and technologies that Europe is putting in place to regain the leadership of innovation in the field of photovoltaics. The DISC project is aiming to push the limits of conventional double sided silicon solar cell with selective carrier junctions; this will allow the extraction of light generated charge carriers without recombination. Such contacts allow simple device architecture – non patterned double-side contacted solar cells, which can be fabricated by upgrading existing production lines. It aims to target efficiencies >25.5% on large area cell and >22% at module level while demonstrating pilot manufacturing readiness at competitive costs. The NextBase project, deals with the development of innovative high performance c-Si solar cells and modules based on the interdigitated back-contacted silicon heterojunction (IBC-SHJ) solar cell concept targeting cells with efficiency above 26.0% and corresponding solar modules with efficiency above 22.0%. At the same time, the NextBase project pursues the development of a new industrial manufacturing tool and low-cost processes enabling a competitive IBC-SHJ solar module cost of < 0.30 €/Wp. The final goal of the AMPERE is the setting-up of an innovative 100 MWp full-scale automated pilot line in production environment while preparing the next steps to 250 MWp and the GWp scale. Within this framework, the aim of AMPERE is to develop an EU innovative and sustainable manufacturing full-scale automated industrial pilot line, to produce heterojunction technology (HJT) silicon solar cells and modules in bifacial configuration. The expected impact of AMPERE is a regain of competitiveness in the entire EU PV value chain (from materials, to equipment and cell/module manufacturers). All the three projects have shown they can achieve the set goals. In addition, there were excellent invited talks about the future of photovoltaics in Europe.


The workshop has been opened by an introductory talk by Anis Jouini (CEA-Ines): PV in Europe, the new era. He individuated the roadmap for a competitive European PV manufacturing in the development of the high efficiency, a new capacity for Europe of 200 GW, a LCOE between 2-5 eurocent together with a renewed attention to standardization and sustainability of the PV products.


The Becquerel Prize 2019 awarded Pierre Verlinden presented his invited talk “PV Technology Challenges for the Next Decade”.
“To fulfil the Paris COP21 Agreement we are allowed to generate only 800 GT of CO2, then zero. The next 10 years will be decisive. Only a fast transition over the next 30 years to net-zero CO2 emission allows to meet +1.5C -2°C. If we don’t, the consequences will be disastrous. The World is probably right now on a path of > +4°C by the end of the Century. We are approaching the point when it will be too late to act. A +4°C World might only support 1 billion people. The only possible solution is a 100% Renewable Energy by 2050” he stated.


Walburga Hemetsberger (CEO Solar Power Europe) illustrated a new era for solar growth in Europe: Solar – Powering Europe’s Green Deal.
She presented ‘Silver Frog’; the project proposal foresees the construction of a cutting-edge 2 GW/year solar PV manufacturing facility which would provide over 10 GW of installed PV capacity. Combined with wind installations, it would provide for the production of 100% renewable hydrogen, transported by gas pipelines to hard-to-decarbonise industries, such as steel and chemicals. Over a period of eight years, the project is estimated to produce 800,000 tonnes of renewable hydrogen, and reduce 8 million tonnes of CO2 emissions, each year – approximately the CO2 footprint of the whole city of Brussels. At least 6,000 jobs are expected to be created as a result of the project. The speech has ranged from the market aspects to the political context in which the European Commission and the association of European manufacturers of photovoltaics will work together to support the European policy on renewables.

 

To complete the workshop an interesting round table has seen important protagonists of the European photovoltaic sector, from R&S to Industry, discuss around the technical, economic and normative aspects necessary for a full revamping of the sector in Europe.
