In the design and fabrication of photovoltaic cells, acceptors are as important as donors. Quite a large variety of donors exist while most common acceptors are fullerene based and these acceptors are limited in properties. Herein we report the design, optoelectronic and photoelectrochemical properties of three new stannum‐based bimetallic nanoparticles (SnTi, SnV and SnCr) combined with poly(3‐hexylthiophene)(P3HT) as electron donor material in the fabrication of bulk heterojunction photovoltaic cells. SnCr nanoparticles displayed excellent electrocatalytic and photoelectronic properties. Solar cell device constructed with P3HT as donor and SnCr as acceptor achieved an open circuit voltage ca. 1 V and efficiency 1.46 %.
