Analysis of vertical multijunction solar cells

ABSTRACT

The electrical parameters saturation current density; series resistance; shunt resistance; ideality factor and photocurrent density of multi-junction solar cells have been extracted from characteristics data J-V. We found that experimental results on photo-current voltage characteristics can be reliably reproduced using electrical extraction parameters using the non-linear least-squares method. We realized high voltage silicon solar modules with a voltage of up to V_oc =25.491 V at 500 suns.
