染料敏化太阳电池内部光路折转对电子传输特性的影响
Effect of light path folding on the properties of electron transport in dyesensitized solar cell
摘要
Abstract
In this paper, an electron continuity equation with light path folding is developed based on the reflection structure of photoanode in a dye sensitized solar cell （DSC）. The characteristics of modulated photocurrent frequency response are calculated, and the effects of light path folding on electron transport property are studied under different absorption and reflection conditions. Intensity modulated photoeurrent spectroscopy measurements show that the established model reflectes the actual characteristic of the response to modulated photocurrent frequency when the light path is folded inside the DSC. The kinetic of electron transfer process depends on the light absorption coefficient, film thickness and large particle reflection ability and other factors in DSC with reflector structure. The deep trap is filled and residence time of electron in trap is shortened. It is attributed to the fact that the light path folding reduces the effect of trap/detrap and accelerates the electron transportation.关键词
