The result indicates the efficiency of the solar cells increases with the increasing light soaking time and finally reaches saturation. A preservation time in dark condition above 26 h degrades the efficiency. Besides, by applying different monochromatic illumination, the reason leads to the light soaking effect was explored.
LEDs offer advantages over monochromators, including more compact size, higher intensity, stability, and simpler modulation using electronics. On the other hand, they have broader bandwidths, which complicates the data analysis. The solar cells to be measured are biased with halogen lamps up to a lighting level of 1000 W/m 2.
We have developed a setup for measuring differential spectral responsivities of solar cells in bias light conditions. The setup uses 30 high-brightness LEDs for generating a quasi-monochromatic light source covering the wavelength range of 290–1300 nm.
Light soaking effect was observed in the ZnS/p-Si heterojunction solar cells for the first time. The device performance is found to increase with the increasing light soaking times and finally reaches saturation. Besides, when the illumination stops, the power conversion efficiency (PCE) would decrease slightly.
Light soaking effect is observed in ZnS/p-Si solar cells for the first time. Different light soaking conditions were systematically explored. A model is proposed to qualitatively explain the light soaking effect. Deep-level transient spectroscopy was applied to verify the proposed model.
Differential spectral responsivity for the 15 × 15 cm 2 bifacial solar cell. Bias light conditions ranging from all lights off to full lighting on both sides (100% front + 30% rear) are indicated in the figure legend. The solid purple line represents the ideal responsivity assuming 100% quantum efficiency
