Applied Science and Technology A design and realization of solar cell test equipment

The scheme of solar cell test equipment based on single- chip computer was proposed. The results of hardware and application software design and debugging were given By programmable electronic load and external compensation power, the test and calculation of primary parameters such as voltage -current character, open circuit voltage and short circuit current could be realized. The man- machine interface was developed under the virtual instrument development circumstance. Through this interface, the control of test procedure and the input of parameters of cell could be implemented, and the curve, data list and report could be displayed and created. The experiments indicated that the equipment has the advantages of data accuracy, information integrity and convenience of operation. It could be used to character test and analysis of solar cells.
