Standard test conditions (STC) for panels are 1000W/m2incoming radiation, panel oriented normal to thesun, and 25 °C.  If all other conditions are the same butwe decrease the temperature, how will this affect power output ofthe panel, relative to its STC rating?  Why?
How is solar energy wasted when the frequency of incoming solarradiation is too low? When the frequency is too high?
How does a multi-junction solar cell improve efficiency comparedto a single-junction cell?
