Solar Cell Efficiency Record Set Using Heraeus Metallization Paste

A record for PERC (“passivated emitter and rear cell”) of 21.7% has been reached in .  The record cells were processed at the solar cell R&D line at in Freiberg using ’ front-side metallization paste.

Dr. Weiming Zhang, Senior Vice President, Head of Global Sales & Head of Global Innovation for the Heraeus Photovoltaics Global Business Unit, says:  “We are proud of our efforts to supply our metallization pastes and research and development expertise in achieving this record performance.  Heraeus has several paste formulations that are ideal for PERC applications.  We also have the capability to modify our formulations for special cell design characteristics.   We feel that our ability to work closely with our partners allowed us to provide a front-side paste that reduced recombination losses at the surface and minimized shading after the metallization process.”

The cells, based on crystalline p-type silicon wafers, were manufactured using industrial production processes, meaning that they can be quickly placed into mass production. SolarWorld will offer modules with 300-watt and more featuring this technology beginning this fall.

SolarWorld AG possesses the largest production capacity worldwide to manufacture this high-performance technology, which the company is going to expand.

Heraeus has a long history of working with leading academic and industrial researchers to increase the performance and efficiency of advanced cell technologies.  The Heraeus Photovoltaics Business Unit is a  developer and manufacturer of silver metallization pastes for the photovoltaic industry.  These metalliztion pastes are specially formulated to provide higher efficiencies and wider processing windows, resulting in better yields and higher output for cell manufacturers.
