Single crystals of n‐WSe 2 have been grown by the chemical vapour transport (CVT) technique, using Br 2 , TeCl 4 , and SeCl 4 as transporters. Crystal lattice parameters have been determined for all the crystals grown above with an X‐ray diffractometer. The composition of the above crystals were examined by energy dispersive analysis of X‐rays (EDAX). Optical and some electrical transport measurements are carried out to judge the semiconducting nature of the as‐grown crystals. Photoelectrochemical (PEC) solar cells were frabricated by using these crystals as photoelectrodes and platinum grid as counter electrode in an aqueous iodine/iodide solution. Some of the PEC cell parameters were determined. The results thus obtained have been discussed in detail.
