Abstract
AM 0 PV parameters of large-grain, {112} orientated chalcopyrite CIGS2 thin films solar cells on 127µm thick SS flexible foil for space power were: Voc = 802.9 mV, Jsc = 25.07 mA/cm2, FF = 60.06%, and efficiency 0 = 8.84%. Detailed current versus voltage analysis gave values of series resistance Rs, shunt resistance Rp, diodefactor A, and reverse saturation current Jo of ~0.1 Ω cm2, ~600 Ω cm2, ~2.2 and ~1.85x10-8 A cm-2 respectively. Asharp QE cutoff was observed at CIGS2 bandgap of ~1.50 eV. Higher foil roughness resulted in a preliminary low 4.06% (AM 1.5) efficiency of CIGS2 solar cell on 20 µm thick SS foil. Present specific power of 65 W/kg can be increased by over 10 times with 10% AM 0 CIGS cells on 20-25 µm thick SS or Ti foils.
