8th World Conference on Photovoltaic Energy Conversion; 1099-1104, In this work we give an overview of the module monitoring results achieved within the H2020 funded project called HighLite. A dedicated online monitoring platform has been developed for the project to group and treat the data from all partners with homogeneous procedures. Monitoring of advanced prototype modules developed in the project and based on various cells and interconnection approaches, like silicon-heterojunction (SHJ)-shingle, TopCon-shingle, cut interdigital back-contact cells (cut-IBC) are reported. We describe key learnings from monitoring modules for various applications including building-applied PV (BAPV) and building-integrated PV (BIPV). Annual energy yield up to 1900 kWh/kWp is expected in Cadarache (France) based on HighLite PV technology. Temperature corrected performance ratios are used for a ranking of the new technologies against the reference PERC modules.

38th European Photovoltaic Solar Energy Conference and Exhibition; 533-537, The EU crystalline silicon (c-Si) PV manufacturing industry has faced strong foreign competition in the last decade. To strive in this competitive environment, the EU c-Si PV manufacturing industry needs to focus on highly performing c-Si PV technologies and on reducing environmental impact (lower CO2 footprint, improved sustainability, recyclability, etc.). In this work, we give an overview of the latest results achieved within the H2020 funded project called HighLite which addresses the work programme LC-SC3-RES-15-2019: Increase the competitiveness of the EU PV manufacturing industry. We report the progress made when implementing novel layers and processes in existing pilot-lines producing high-efficiency n-type silicon heterojunction (SHJ) cells with a shingle layout and interdigitated back-contact (IBC) cells with passivated contacts. In particular, we present the work done together with several industrial partners towards innovative production equipment for assembly of cut-cells into PV modules. Finally, we explain key learnings made so far when tailoring c-Si PV modules for various applications including building-applied PV (BAPV), building-integrated PV (BIPV) and vehicle-integrated PV (VIPV).

35th European Photovoltaic Solar Energy Conference and Exhibition; 67-70, Modules manufactured with shingled crystalline silicon solar cells have become more prevalent as of late. For these structures, the electrical and mechanical properties of the electrically conductive adhesive (ECA) used to attach the shingles together plays a key role in the final performance of the assembled modules. In this work, ECAs based on different chemistry platforms are presented and the impact of their properties (such as adhesion, bulk electrical conductivity, contact resistivity to Ag ribbons and storage modulus) on module thermocycling reliability (-40/85˚C) and static mechanical load performance is studied. In particular, full-sized modules were built with ECAs with a wide range of storage moduli -- from very flexible, to very rigid materials -- and it was found that materials with the highest storage modulus show a larger power loss upon standard mechanical load tests. In addition, one-cell mini-modules were built to study the effect of the contact resistivity on the reliability performance, with findings suggesting that ECA usage is the main contributor to the series resistance increase upon cycling. Lastly, the work also proves that other materials in the mini-module manufacture process, such as the backsheet, play a critical role in reliability.
