Transient behaviour of short-circuit current and open-circuit voltage in a-Si:H solar cells

Abstract

Experimental results show that the transient behaviour of the open-circuit voltage is the same for red, yellow and green monochromatic light. In contrast, the transient behaviour of the short-circuit current is strongly dependent on the wavelength of the illuminating light in the time range $\text{(1–10) × 10}{}^{\mathrm{-4}}\text{s}$. An explanation is given for these results in terms of the localized character of the electronic states.
