Influence of Annealing Temperatures on Properties in Chelate Based CuI Thin Films

Copper(I) iodide (CuI) has received considerable scrutiny as a hole transport material in solid-state dye-sensitized solar cells (ss-DSSC), amidst challenging issues such as rapid crystallization, pore filing, and dye desorption. This paper would attempt to study the influence of heat on various pr...
