Lead iodide considers as one of the chemicals that is on the Special Health Hazard Substance List (SHHSL) and it is consider as carcinogenetic substance. In this study films of 12µm thick toxic PbI2 pure and doped with various atomic volumes doping concentration of Al (1, 2, 3, & 4 mil) were deposited, and their physical properties were investigated different poisonous concentrations of hazardous lead iodide. The films were set by screen printing on glass substrates at room temperatures. X-Ray diffraction of deposited films shows raising the peak intensity with increasing dopant concentration. Energy gap decreases with increasing dopant concentration. Doping of Lead Iodide film with specific amount of Al will increase the electrical resistivity with increasing the dopant concentration, while decrease mobility.
