摘要：

Photocurrent enhancement and improvement in solar cell performance are found when the interface between ZnO and polythiophene layers is modified with insulating alkanethiol self-assembled monolayers. This result is correlated with increased structural order in the polymer and interchain contributions in the photocurrent, suggesting that improved exciton diffusion or reduced electron-hole recombination can outweigh the impedance in electron transfer at the heterojunction interface.
