Abstract
The present invention provides a microwave annealing method for a plastic substrate. The method comprises pulsed microwave annealing to an organic photo-voltaic device to avoid warpage and degradation of the plastic substrate. Utilizing pulsed microwave annealing method can improve the wettability of the organic layer on the plastic substrate verified by contact angle measurement, and achieving the organic solar cell fabricated with higher power conversion efficiency.
