TiO<jats:sub>2<\/jats:sub> film was prepared by screen printing, CdS\/TiO<jats:sub>2<\/jats:sub> compounded film was synthesized by SILAR method. XRD and\n FE-SEM was used to characterize the TiO<jats:sub>2<\/jats:sub> and CdS\/TiO<jats:sub>2<\/jats:sub> samples. Multi-cycle photoelectric properties of TiO<jats:sub>2<\/jats:sub> and CdS\/TiO<jats:sub>2<\/jats:sub> with uv light on and off were evaluated by testing the photocurrent. On one hand, under the same bias voltage, CdS\/TiO <jats:sub>2<\/jats:sub>showed\n a higher photocurrent than that by TiO<jats:sub>2<\/jats:sub>. The reason for this result should be ascribed to the compounded structure in CdS\/TiO<jats:sub>2<\/jats:sub>, with which the separation and transfer of photogenerated electron-hole pairs could be improved. On the other hand, with the testing cycle number\n increased, the photocurrent amplitudes of TiO<jats:sub>2<\/jats:sub> and CdS\/TiO<jats:sub>2<\/jats:sub> increased. These results suggested that the time to reach a stable photocurrent value for TiO<jats:sub>2<\/jats:sub> and CdS\/TiO<jats:sub>2<\/jats:sub> is much longer than one cycle time (300 S). To illustrate the increased photocurrent\n amplitude value cycle by cycle, the photocurrent of CdS\/TiO<jats:sub>2<\/jats:sub> to a much longer time (more than 4000 seconds) was also tested. To explain these results, corresponding possible illustrations were presented.<\/jats:p>","DOI":"10.1166\/jnn.2021.19465","type":"journal-article","created":{"date-parts":[[2021,5,13]],"date-time":"2021-05-13T04:32:53Z","timestamp":1620880373000},"page":"5642-5647","source":"Crossref","is-referenced-by-count":0,"title":["UV
