For the measurement of the temperature of photovoltaic cells, the actual power generation of photovoltaic cells depends not only on the solar radiation absorbed and transmitted but also on the actual operating temperature of photovoltaic cells. When the rated temperature is increased by 1°C, the output of photovoltaic cells will be reduced by about 0.5% of the rated

The dark volt-ampere characteristic refers to the relationship between the current flowing through the solar cell and the applied voltage when there is no light. The basic structure of a solar cell is a large-area planar PN junction, and the PN junction area of a single solar cell unit is much larger than that of an ordinary diode.

1. Introduction The I–V characteristics of solar cells measured under dark and illuminated conditions provide an important tool for the assessment of their performance. The dark characteristics are the easiest way to estimate the quality of the junction and the grid and contact resistances.
The use of Dark IV curves in solar cell analysis relies on the principle of superposition. That is, in the absence of resistive effects, that the light IV curve is the dark IV curve shifted by the light generated current. While this is true for most cells it is not always the case.
The test needs to change the light incidence angle of the solar cell, and the light from the solar simulator shines vertically on the solar cell from the bottom up, so it is not easy to change the angle, so the light incidence angle can be adjusted by changing the tilt angle of the solar cell.
The 2-diodes model is used to describe the dark I-V curves of the PV cell . (1) to a set of measured data using a nonlinear squares method of dark I-V measurement data. The current-voltage (I-V) curve for each component cell in the PV module is characterized by PV cell specific parameters' values.
2. During the use of solar cells, the light incidence angle should be kept in the range of 0°–30° to ensure that the short-circuit current, maximum working power and photoelectric conversion efficiency of solar cells are less affected by the light incidence angle and improve the efficiency of solar energy utilization.
