Abstract

The testing device is in use for measuring photoelectric properties of photovoltaic conversion materials and parts. In the device, xenon lamp simulates sunlight source. Optical fiber (21) of guiding light beam connects grating monochromator with xenon lamp, and optical fiber (22) of guiding light beam connects grating monochromator with testing dark box, where there are photocell and sensor of photometer inside. Output end of photocell is connected to voltage / current meter. Output end of sensor of photometer is connected to photometer. Output ends of photometer and voltage / current meter through data acquisition interface is connected to computer for in site measuring luminous intensity irradiated on photocell. Sensor of photometer is placed on the position the photocell located.

Description

technical field [0001] The invention is a device for measuring the photoelectric properties of photoelectric conversion materials and devices, especially a test instrument for photoelectric conversion properties of photoelectrochemical solar cells. Background technique [0002] There are two-electrode and three-electrode methods for testing photoelectric properties of photoelectric conversion materials and devices (such as photovoltaic cells), and the two-electrode method is more commonly used. What has been reported are discrete devices assembled by some research institutions. A pulsed xenon (Xe) lamp was used to simulate the solar light source to illuminate the photocell, and the performance parameters of the photocell were obtained by measuring the voltage and current data of the photocell under the illumination of the simulated light source and comparing the measurement data of the standard photocell. The whole process has a low degree of automat...
