Abstract: The CuInSe2absorber layers were deposited on Mo/glass substrates by using the spray coating method (SCM). At first, the CIS powder was ground into nanoscale particles; then the 6 wt% CIS particles were dispersed into isopropyl alcohol (IPA) to get the solution for SCM. 0.05 mL CIS solution was sprayed on the 2 cm × 1 cm Mo/glass substrates, and then the CIS solution films were annealed in a selenization furnace under different parameters. At first, the extra 0.2 g Se was put in the furnace, the selenization ti…
