Intersolar: Q-Cells reaches 13.0% solar thin-film efficiency

Q-Cells has reached an efficiency of 13% with its mass-produced CIGS solar thin-film modules Q.SMART UF manufactured by subsidiary Solibro GmbH.

The efficiency was measured by the Fraunhofer Institute for Solar Energy Systems in Freiburg, Germany. With a power output of 97.4 Wp under standard test conditions for a Q.SMART UF (former CIGS SL1) solar thin-film 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 thin-film solar module's aperture area efficiency is 14.2%, Q-Cells says.

The increase of average efficiency associated with the new Q-Cell 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) solar thin-film modules within the following next months, the solar company adds.
