Effect of Mechanical stress on Organic Photovoltaics due to bending

Abstract

This thesis discusses about the effect of bending on open circuit voltage of organic photovoltaics (OPVs). The OPVs were provided by VTT technical research center of Finland which has been involved in manufacturing of lightweight, ultra-thin OPVs.

The OPVs provided were bent in three different angles: 30°, 60° and 90°. The differences of bending the OPVs in these different angles was studied. For each bending angle three OPVs were used and bending were done differently. Two additional tests were also performed to check the effect of heat and orientation of OPV making a total of 11 OPVs to be experimented. The thesis is does not concern on improving the efficiency, rather analyses degradation of OPVs by bending.
