Abstract

The invention discloses a silicon semiconductor solar cell parameter measuring instrument. An A/D front-end circuit made of LM358 is used for controlling an input signal to be within a detection range of an A/D module; a programmable resistor manufactured by a relay module is used as a load of an A/D front-end circuit, and parameters are accurately measured through continuous linear change; an LCD screen displays the parameters of the solar cell and the working mode of the single-chip microcomputer is controlled by a screen touching mode. Measurement of voltage and current is completed in an STM32F407 chip, the output power of the battery under different load conditions is calculated in real time, a current-voltage curve and a power-voltage curve are drawn, and a fill factor is calculated while the maximum power point is obtained. The measuring instrument utilizes the modern electronic technology and the advanced single-chip microcomputer technology to realize the intelligent calculation of the output power of the solar cell and the automatic search of the maximum power point, and has the advantages of high measurement precision, fast speed measurement, visual result, low cost, high experiment efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a silicon semiconductor solar cell parameter measuring instrument. Background technique [0002] After the two industrial revolutions, fossil fuels such as coal, oil, and natural gas have been widely used in all aspects of production and life. However, these are traditional non-renewable energy sources, long-term unlimited use will not only cause a global energy crisis but also cause serious environmental pollution problems. Therefore, the development of huge reserves, clean and pollution-free renewable energy has become the consensus of today's society. [0003] Compared with conventional energy sources, solar energy has three advantages: first, it is the most abundant energy available to human beings; second, on the earth, as long as there is sunlight, there is solar energy, so that we can develop and utilize it locally , there is no transportation problem, es...
