Sommario:
- <p>Abstract - Zinc oxide (ZnO) is a direct wide-bandgap semiconductor with high exciton binding energy of ~60meV. In search for lead free perovskite material, considering the application of ZnO in solar cell, we studied the electrical and optical property of a new Zn based perovskite materials namely methyl ammonium zinc triiodide (CH3NH3ZnI3). We also compared the results with more popular methyl ammonium lead triiodide (CH3NH3PbI3) used in perovskite solar cells. The band gap and x-ray diffraction data were also analyzed and compared. It was observed that the CH3NH3ZnI3 absorbs electromagnetic radiation in far UV region. From the X-ray diffraction pattern, it was clear that CH3NH3ZnI3 retains the original cuboctahedral crystal structures as CH3NH3PbI3.</p>
