In this study, the Mo-electrode thin films were deposited using two-stepped process and the high purity copper indium selenide-based powder (CuInSe2<\/sub>, CIS) was fabricated by using hydrothermal process by Nanowin Technology Co. Ltd. Because the CIS powder was aggregated into microscale particles, the CIS power was ground into nano-scale particles. 6 wt% CIS particles were mixed and dispersed into isopropyl alcohol (IPA). A new non-vacuum thin-film deposition process, spray coating method (SPM), was investigated to deposit the high-densified CIS absorber layers. 0.1 ml CIS solution was sprayed on the 20 mm×10 mm Mo\/glass substrates and then the CuInSe2<\/sub> thin films were annealed in a selenization furnace using N2<\/sub> as atmosphere. The annealing temperature and time were set at 550o<\/sup>C and 5 min, and 0.0g~0.6g extra Se content was added in the furnace. The influences of extra Se content on the densification, crystallization, resistivity (ρ<\/em>), hall mobility (μ<\/em>), and carrier concentration of the CIS absorber layers were well investigated in this study.<\/p>\r\n","references":"[1]\tM.
