摘　　要：研究了太阳能光电材料光电转换效率(Incident Photon-to-Current Efficiency,IPCE)的测试方法。基于VC++,采用异步等效法,研制成了一种由单色仪、斩波器、恒电位仪、锁相放大器、计算机组成的光电材料光电转换效率测试系统。该系统可对各种半导体材料的IPCE性能进行测试,能正确实时显示所测样品的谱图。该系统具有较高的自动化程度和较强的数据处理功能,并广泛用于本科研组的太阳光催化分解水制氢材料光电性能的测试,测试结果稳定可靠。Testing technique of the incident photon-to-current efficiency （IPCE）of photoelectric semiconductor materials has been carefully studied. Based on VC ＋ ＋ and asynchronous method, a solar photoelectric materials IPCE system has been developed. The system contains auto-scanning grating monochromator, chopper, potentiostat, lock-in ampli- fier and computer. The system can be widely used for characterisation of the photoelectric properties of semiconductor materials with real-time display and is of automatic measuring performance and powerful function for data processing. It has been intensively used for testing the photoelectric properties of semiconductor materials for water splitting in our laboratory.
