Spatially resolved photoluminescence imaging of essential silicon solar cell parameters

We present a method to image the following spatially resolved parameters of a solar cell: voltage V
_xy
, current density J
_xy
, power density P
_xy
, efficiency η
_xy
, series resistance R
_s,xy
, fill factor FF
_xy
and dark saturation current densities of a two diode model J
_01,xy
and J
_02,xy
. The algorithm determines this set of self-consistent parameters by using a minimum of five electrical biased photoluminescence images.
