From PERC to Tandem POLO and p /n Poly Si Tunneling Junction as Interface between Bottom and Top Cell authored by Robby Peibst, Michael Rienäcker, Byungsul Min, Christina Klamt, Raphael Niepelt, Tobias F. Wietler, Thorsten Dullweber, Eduard Sauter, Jens Hubner, Michael Oestreich, Rolf Brendel Abstract We present a novel cell concept that combines the tandem cell approach with the passivated emitter and rear cells PERC mainstr...

IUW at the LUH Summerfest: Over 90 percent have heard of microplastics, but only 48 percent already pay attention to them when shopping. 09/27/2022 On the 14th of July 2022, the Institute for Environmental Economics and World Trade IUW took part at the LUH summer festival.

Three Terminal Bipolar Junction Bottom Cell as Simple as PERC Towards Lean Tandem Cell Processing verfasst von Michael Rienacker, Emily L. Warren, Tobias F. Wietler, Paul Stradins, Adele C. Tamboli, Robby Peibst Abstract Silicon based tandem cells are a potential upgrade for the dominating PERC technology and can greatly increase the conversion efficiency.

High Efficiency Industrial PERC Solar Cells for Monofacial and Bifacial Applications verfasst von Thorsten Dullweber Abstract The passivated emitter and rear cell PERC concept is currently rapidly being introduced into industrial mass production and is expected to be the new silicon wafer based solar cell technology standard in the photovoltaics industry.

PERC solar cells with screen printed dashed Ag front contacts authored by Martin Rudolph, Christian Kruse, Helge Wolter, Bettina Wolpensinger, Ulrike Baumann, Sonja Bräunig, Melanie Ripke, Tom Falcon, Rolf Brendel, Thorsten Dullweber Abstract The efficiency of PERC solar cells is limited by charge carrier recombination at the Ag front contacts on the emitter.

Quick test for reversible and irreversible PID of bifacial PERC solar cells verfasst von Kai Sporleder, Marko Turek, Nadine Schüler, Volker Naumann, David Hevisov, Clemens Pöblau, Stephan Großer, Henning Schulte Huxel, Jan Bauer, Christian Hagendorf Abstract High voltage stress at the rear side of bifacial PERC cells leads to severe power losses. In contrast to monofacial PERC solar cells, reversible de polarization ...

A Roadmap Toward 24 Efficient PERC Solar Cells in Industrial Mass Production verfasst von Byungsul Min, Matthias Müller, Hannes Wagner, Gerd Fischer, Rolf Brendel, Pietro P. Altermatt, Holger Neuhaus Abstract Many manufacturers choose the passivated emitter and rear cell PERC approach in order to surpass the 20 cell efficiency level in mass production. In this paper, we study the efficiency potential of the PERC appr...

Impact of Ag Pads on the Series Resistance of PERC Solar Cells verfasst von Henning Schulte Huxel, Robert Witteck, Paula Van Laak, Till Brendemühl, David Hinken, Karsten Bothe, Rolf Brendel Abstract Screen printed passivated emitter and rear cells PERC require Ag pads on the rear side to enable solderable connections for module integration.

This bifaciality increases the energy yield of silicon solar modules by up to 25 . Since its first publication in 2015, the PERC cell concept has been rapidly adopted by several solar cell manufacturers due to the very similar process technology of bifacial PERC cells and main stream monofacial PERC cells. We summarize technological challenges, published PERC conversion efficiencies and PERC module ...

Simulation based Efficiency Gain Analysis of 21.2 efficient Screen printed PERC Solar Cells verfasst von Christopher Kranz, Jan H. Petermann, Thorsten Dullweber, Rolf Brendel Abstract Passivated Emitter and Rear Cells PERC with efficiencies well above 20 are likely to become the next mass production technology. A quantification of all power loss mechanisms of such industrial PERC cells is helpful in prioritizing futu...

Industrial silicon solar cells applying the passivated emitter and rear cell PERC concept a review verfasst von Thorsten Dullweber, Jan Schmidt Abstract Even though the passivated emitter and rear cell PERC concept was introduced as a laboratory Type solar cell in 1989, it took 25 years to transfer this concept into industrial mass production.
