- We demonstrate that enhanced device performance of hybrid solar cells based on tetrapod
(TP)-shaped cadmium selenide (CdSe) nanoparticles and conjugated polymer of poly
(3-hexylthiophene) (P3HT) can be obtained by using longer armed tetrapods which aids in better
spatial connectivity, thus decreasing charge hopping events which lead to better charge transport.
Longer tetrapods with 10 nm arm length lead to improved power conversion efficiency of
1.12% compared to 0.80% of device having 5 nm short-armed tetrapods:P3HT photoactive blends.
