The results in Germany show increasing efficiency from 10 to 50 degrees C. The results from Australia show increasing efficiency from 10-30 degrees C and then a slight drop off after. The generic slide shows improving performance up to a cell temperature of about 55 degrees C, then it drops off (but very gently vs other technology PVs). Their thermal annealing effect is pretty interesting.
