Embodiment Construction

[0015] Take a microammeter, a millivoltmeter, a slide wire resistor with a resistance of 100 megohms, wires and a titanium dioxide dye solar cell. The effective area of ​​the titanium dioxide dye solar cell is 2 square centimeters, and it has two metal leads to facilitate the output of photo-generated voltage and current. Connect one output electrode of the titanium dioxide dye solar cell to one input terminal of the ammeter, then connect the output terminal of the ammeter to one terminal of the variable resistor, and then connect the other terminal of the variable resistor to the other terminal of the solar cell An output pole completes the main line connection. Connect the two terminals of the voltmeter to the two output electrodes of the solar cell to read the output voltage of the solar cell. figure 1 It is a circuit diagram of the testing instrument constructed according to the embodiment.

[0016] Use the light emitted by the solar simulator to illuminate the solar cel...

Abstract

The invention provides a portable solar cell J-V curve measuring instrument. The portable solar cell J-V curve measuring instrument is structurally characterized in that the measuring instrument is composed of a voltage gauge, a current gauge, a variable resistor and a wire and operationally characterized in that a resistance value of an externally connected circuit of a solar cell is changed in order to change the output voltage and the output current of the solar cell. The solar cell J-V curve measuring instrument can provide a stable and reliable analyzing test for the solar cell. The basic measuring functions comprise complete I-V curve measuring, complete J-V curve measuring, complete P-V measuring, short circuit current measuring, open circuit voltages measuring, short circuit current density measuring, peak value power measuring, peak value power current measuring, peak value power voltage measuring, energy converting efficiency measuring, fill factor FF measuring and the like. The portable solar cell J-V curve measuring instrument is low in and assembly and manufacture cost and reliable in performance.

Description

1. Technical field [0001] The invention relates to an instrument for measuring the J-V curve of a solar cell, which belongs to the technical field of electrical equipment for power generation. 2. Background technology [0002] A solar cell is a device that responds to light and converts light energy into electricity. Solar cell testing instruments play a pivotal role in the analysis, characterization and development of photovoltaic products. Existing solar cell testing instruments are complex in composition, bulky in size and high in cost. Therefore, it is of great significance to develop a portable solar cell testing instrument with low assembly and low manufacturing cost but reliable performance for the vast number of scientific and technological workers and micro high-tech enterprises. [0003] The invention provides an instrument for measuring the J-V curve of a solar battery. The instrument has the characteristics of easy design, small size, low assembly, low manufac...
