This allows for cheaper and much more efficient materials production and minimize materials loss. The separation of materials formation from the module fabrication-allowing for all temperatures and purity precautions-is the very important advantage of the monograin layer based technology. Large area module fabrication proceeds without any high temperature steps in a continuous roll-to-roll process. No up-scaling problems arise as is typical of thin-film technologies since a homogenous powder leads to homogenous modules. The influence of different technological parameters to the materials properties was studied and from CZTS=Cu2(ZnxSn2-x)(SySe1-y)4) monograin powders solar cells have produced with parameters Voc up to 690 mV, fill factors up to 65 % and I sc more than 20 mA/cm2. It was founded that changing of the sulfur/selenium ratio allows a change of 1.04 and 1.72 eV the band gap of Cu2(ZnxSn2-x)(SySe1-y)4.
