报告简介:

Organic PV has recently experienced a boost of performance which brings it into the same league as inorganic thin film technologies. Their unique properties like semitransparency and flexibility make them ideally suited for building integrated photovoltaic (BIPV) installations. In order to make use of the recent progress for commercial applications, high efficiency lab cells have to be turned into visually attractive full size modules without significant losses in performance.

This talk will give a short overview of how the “Solar Factory of the Future” develops processes and processing equipment for upscaling promising lab scale solar cells to commercially relevant sizes and production volumes. As for BIPV applications an appealing appearance is essential, we have developed a variety of techniques which allow us to produce modules without visible electrodes or interconnects. These techniques comprise interconnect formation by laser ablation or by ink jet printing and the use of silver nanowire (AgNW) electrodes. By blending AgNWs with charge extraction materials, the module can be printed in only three coating steps, rather than five as previously, which simplifies the production process.

Another challenge on the way to commercial production is the formulation of inks which conform to legal regulations, i.e., do not contain halogenated solvents, without compromising the efficiency of the resulting solar modules. By employing Hansen’s solubility parameters, we have developed a method which allows us to identify appropriate “green” solvents which yield the same efficiencies as their halogenated counterparts.

Finally, it will be shown how the printed modules can be encapsulated by directly coating the barriers on top of the devices. This step avoids costly and possibly harmful lamination processes and is even applicable for the encapsulation of organic electronic devices on 3D surfaces.

 

个人简介

Dr. Hans-Joachim Egelhaaf is the head of the group “Solar Factory of the Future” of the Bavarian Center for Applied Energy Research (ZAE Bayern) in Nuremberg. His current focus is on the transfer of organic and hybrid photovoltaic lab technologies to industrial R2R processes.

He received his PhD degree from Tübingen University for studies on the photophysics of oligothiophene films. After his habilitation in Physical Chemistry in 2005 he joined the Politecnico di Milano/Italy to do ultrafast spectroscopy on organic-inorganic hybrid systems. In 2006, he moved to Linz/Austria to work with Konarka. In 2009 he joined the German branch of Konarka in Nuremberg. After the transition of Konarka to Belectric OPV in 2012 he became Director of the R&D department. Since 2014 he is with the ZAE Bayern.

He has co-authored more than a hundred papers (h-index 48) and several patents.
