Abstract
Cu2ZnSnSe4 monograin powders with different Zn/Sn concentration ratios were synthesized from binaries and elemental selenium, p-type CCu2ZnSnSe4 monograins of stannite structure had tetragonal shape with rounded edges. PL spectra showed one symmetrical band with peak position at 0.81 eV. Monograin layer solar cell structures graphite/Cu2ZnSnSe4/CdS/ZnO had open circuit voltage over 400 mV, short circuit current 15.5 mA/cm2 and FF41 %Keywords
