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 insert ignore into journalissuearticles values(m-Si); and polycrystalline silicon solar cell insert ignore into journalissuearticles values(p-Si);, under various humidity conditions. Current-voltage insert ignore into journalissuearticles values(I-V); and power-voltage insert ignore into journalissuearticles values(P-V); characteristics are achieved simultaneously for each sample, and the relationship between the short circuit current insert ignore into journalissuearticles values(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 oC, respectively. It is unequivocally reported in literature that current parameters are not noticeably affected by the rise in cell temperature up to 20 oC. Therefore, any deviation from the linearity between solar intensity level insert ignore into journalissuearticles values(G); and Isc is attributed to the impact of relative humidity. The tests repeated for low and moderate solar intensity levels insert ignore into journalissuearticles values(257-482 W/m2); reveal that the linear relationship between G and Isc 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
