The developed CZTSe grain size was confirmed as 8μm to 20μm. The second heating stage was helpful in inducing crystallization and was important for grain growth. For the nonvacuum approach, nanosized Cu, Zn, and Sn powders were chosen for preparing inks. Ceramic Al2O3 was used instead of glass to prevent the thermal decomposition of the substrate. A nanosized Cu(In,Ga)Se2 layer was coated on a Mo electrode to provide a barrier to avoid direct contact of Cu, Zn, and Sn with Mo. The selenization under the combination of two selenide pellets played a crucial role in preparing the CZTSe absorber. The fabricated CZTSe solar cell device showed power conversion efficiency of 1.14%, open-circuit voltage of 130mV, short-circuit current density of 33.1mA/cm2, and fill factor of 0.265.
