Abstract: İnvestigation of the fffect of boric acid content on the structural and optical properties of ZnO films prepared by spray pyrolysis techniqueBoron doped ZnO films were prepared by spray pyrolysis technique at 450 °C substrate temperature, which is a low cost and large area technique to be well-suited for the manufacture of solar cells, using boric acid (H3BO3) as dopant source, and their properties were investigated as a function of doping concentration. The changes observed in the energy band gap and structural properties of the films related to the boric acid concentration are discussed in detailX-ray analysis showed that the films were polycrystalline fitting well with a hexagonal structure and have preferred orientation in (002) direction. And optical band gap of the undoped and B-doped ZnO films were found to vary from 3.46 to 3.29 eV.
