The effect of heat treatment on bismuth oxyiodide thin films for lead-free perovskite solar cells

Lead-free bismuth oxyiodide (BiOI) perovskite solar cells (PSCs) have been successfully fabricated using successive ionic layer adsorption and reaction technique. The effect of heat treatment temperature on thickness, conductivity and microstructure of BiOI thin films has been studied prior to the d...
