- •
We design the experiments to understand interrelationships between morphology and performance parameters.
- •
FF increases with the increased P3HT phase purity and the decreased PCBM aggregate thickness.
- •
VOC increases with the decrease of P3HT conjugate length.
- •
JSC relates to the interfacial region area and the phase purity of P3HT.
- •
The devices having large PCBM crystals can obtain good PCE if they have enough interfacial areas.
