amorphous silicon solar cells are investigated. The
dominant forces driving the increased efficiency in
summer are identified, from long-term measurements, to
be thermal annealing and spectral variations. A method for
correcting for changes in the incident spectrum is applied
in order to correct for the seasonal changes. In a second
step, the fill factor is investigated in order to establish the
magnitude of thermal annealing seen by these devices.
The magnitude of each effect is investigated.
