Bitterfeld-Wolfen, 9 June 2010 – Q-Cells sets again a world efficiency record for mass-produced CIGS thin-film modules. The Fraunhofer ISE has confirmed a total area efficiency of 13.0 % for a Q-Cells Q.SMART UF solar module manufactured by Solibro GmbH.
The record efficiency was measured on June 1, by the renowned Fraunhofer Institute for Solar Energy Systems in Freiburg, Germany. With a power output of 97.4 Watt peak (Wp) under standard test conditions for a Q.SMART UF (former CIGS SL1) module with 0.750 m² area, a total area efficiency of 13.0% was confirmed. Moreover, with an aperture area of 0.684 m², the module's aperture area efficiency is 14.2%, which brings it to the world lead based on the record efficiency table compiled by Progress in Photovoltaics. According to the journal, the previous record of 13.5% was held by a module just half the size which – unlike the Q-Cells Q.SMART was not mass-produced.
In September 2009, the previous record (13.5% aperture are efficiency, 12.3% total area efficiency,) was already achieved with a SL1 module out of series production. The achievement of the 13.0% total area efficiency benchmark and the 14.2% aperture area efficiency record is the result of continuous and persistent optimization of the CIGS production processes, and confirms the position of the Q-Cells CIGS modules as a premium product for residential, commercial and industrial roof-tops and façades. Furthermore, the increase of average efficiency associated with the new record result further provides the basis for a future introduction of a new “95 Wp power class” (with positive sorting +5/-0 Wp) for the “Q.SMART (SL1-Framed) and Q.SMART UF (SL1) modules within the following next months.
