Recording of Tuesday, June 18, 2024 | The smarter E Europe | Conference Program | Language: English | Duration: 10:08 .
The session "What's Hot in PV" features a panel of distinguished speakers led by Dr. Harry Wirth from Fraunhofer IEC. The focus is on recent advancements in photovoltaic (PV) technology, particularly tandem perovskite silicon modules which have achieved record industrial efficiencies of 25%. Measurement challenges for these modules are addressed through advanced solar simulators with precise calibration methods. Significant progress has also been noted in screen printing technologies, reducing finger thickness from 70 microns to as low as 14 microns since 2013. Companies like Highline and Lumet have developed even narrower fingers with widths below 20 microns and down to just 5 microns respectively. Innovations extend to cell interconnection techniques such as shingling, resulting in highly homogeneous matrices suitable for building integration. Additionally, the MorphoColor coating technology offers colored PV modules without substantial efficiency loss due to its high transmittance rates between 92-96%. Further integrations include PV applications in vehicles that can contribute significantly to annual driving range reductions on charging station visits. On power conversion front, raising voltage limits up to medium voltages (2-2.4 kV input) allows material savings and improved system performance; exemplified by Jinko Solar's new certified module and Fraunhofer’s medium voltage string inverter. Molly Morgan from Exawatt will continue the discussion focusing on manufacturer data analysis and trends within module efficiency improvements.

The advances in technology along the solar value chain in recent years have been breathtaking: Innovations have included considerably larger wafers, new cell technologies, much higher-efficiency solar modules, smarter inverters with management systems that can control fully electrified high-tech homes and less material-intensive fixed or tracking mounting systems that can be installed faster and boost system yields. This session will provide an overview of the latest technologies.
