Impact of humidity on current parameters of solar cells

Abstract

In this research, impacts of relative humidity on current parameters of solar cells are investigated. An experimental methodology is considered in the research. Outdoor tests are carried out for two different cell technologies, monocrystalline (m-Si) and polycrystalline silicon solar cell (p-Si), under various humidity conditions. Current-voltage (I-V) and power-voltage (P-V) characteristics are achieved simultaneously for each sample, and the relationship between the short circuit current (I sc ) and relative humidity is discussed. During the tests, cell temperature of m-Si and p-Si sample is measured to be in the range of 22.9-36.1 and 21.2-38.9 o C, respectively. It is unequivocally reported in literature that current parameters are not noticeably affected by the rise in cell temperature up to 20 o C. Therefore, any deviation from the linearity between solar intensity level (G) and I sc is attributed to the impact of relative humidity. The tests repeated for low and moderate solar intensity levels (257-482 W/m 2 ) reveal that the linear relationship between G and I sc is maintained for different humidity levels. In this respect, the impact of humidity level on current parameters of solar cells is found to be insignificant

Research on the Passive Cooling System of Solar Photovoltaic Panel Based on Hybrid Solar Chimney and Ventilator

“…In their study titled "A Review on Solar Chimney Systems," Kasaeian et al [37] highlighted key findings related to CFD simulations in this field. Researchers [47][48][49][50][51][52][53][54][55][56] have extensively employed CFD to model airflow and investigate various aspects of solar chimney systems. One area of interest has been studying the impact of geometric dimensions on fluid dynamics and heat transfer within these power plants.…”

“…CFD analyses have also been employed to optimize solar chimney design, including collector and chimney sizing, to maximize power output [54]. Furthermore, through design modifications such as sloping ground designs, CFD research identifies possibilities for improving electricity production in solar chimney power plants, increasing the energy stored in the ground material, and enhancing the upward airflow in the system [55].…”

“…Proper installation and maintenance practices, including regular cleaning and inspection, are essential to increase the reliability and efficiency of photovoltaic (PV) panels [7]. Technology quality is also critical, as reflection from solar module front glass can cause a 4% optical loss, decreasing module efficiency [8].…”

Fixed and adjusted optimal tilt angle of solar panels in three cities in Albania

“…The use of solar energy by solar systems depends on several geometrical parameters. To increase the solar radiation reaching the solar panels, the panels of solar energy systems must install in such a way that the solar radiation falls perpendicular to the surface of the solar panels at any time [8,9]. The angle of incidence is defined as the angle between solar rays and the perpendicular line on the surface, and the amount of the solar radiation incident on a surface is inversely proportional to the value of incidence angle.…”
