The linearly polarization photosensitivity of Si-based solar cells has been investigated. It has been shown that the angular dependence of the open-circuit voltage and light intensity are observed similar change trend. However, a contrary behavior is reported in the angular dependence of the ratio between the open-circuit voltage and polarized light intensity. Through the establishment of a theoretical model and detailed analysis, it is found that the nonlinear effects play a crucial role in the photovoltage responses of solar cells under low illumination. The angular dependence of the ratio of the open-circuit voltage to the light intensity is inversely proportional to the square of the cosine function. This work is very significant for the photovoltaic system research.

At room temperature, the performance of low-concentrating solar cells is investigated experimentally and discussed by theory. The results show that the short-circuit current, which is larger than that of unconcentrated radiation, linearly increases with the light intensity and is directly proportional to the concentration ratio. However, the different behavior is obtained for the open-circuit voltage. The open-circuit voltage is also larger than that at the unconcentrated light level and follows a logarithmic function of the light intensity, showing almost no dependence on the concentration ratios. The main reason is the decrease in internal resistance of solar cell with decreasing spot size, because the increase of incident light intensity leads to an increase of current density. Therefore, an advantage of the low-concentrating photovoltaic systems results from the improvement of the short-circuit current, but not from the open-circuit voltage. This work is very significant for the design of low-concentrating system.

ABSTRACTThe temperature and incident light intensity dependences of open circuit voltage for hetero-and homojunction a-Si:H pin solar cells have been studied. The temperature coefficient of the open circuit voltage decreases from -2.40 to -2.67 mV/°C as the illumination intensity is decreased from 150 to 7mW/cm2 This is consistent with the empirically calculated open circuit voltages. The diode quality factor obtained under dark condition shows high values(l.6–3.0) and strong temperature dependence. On the other hand, the diode quality factor under illumination is less than 1.5 and shows slight temperature dependence. The results appear to be due to the long dielectric relaxation time compared with the carrier lifetime in the i-layer.
