Summary: Poly[3‐(4‐octylphenyl) thiophene] (POPT) and poly[3‐(4‐octylphenoxy) thiophene] (POPOT) with high head‐to‐tail regioregularities have been synthesised and photovoltaic properties have been investigated. POPT‐ blend ‐PCBM exhibits an interesting behaviour in bulk heterojunction whereas POPOT presents poor photovoltaic performances. UV‐visible absorption and AFM images of the blends are presented to explain these results.
