Science park has been widely recognized for its importance to the development of high-tech industries. Boron doped ZnO films which were developed in Science parks 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. X-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. The changes observed in the energy band gap and structural properties of the films related to the boric acid concentration are discussed in detail
