i want to embed C60 into CuPC then i will use it as hole transport layer for Perovskite Solar cells.
Thanks in advance for your expert opinion
Dear Mujahid,
If your evaporator can cope co-deposition of C60 and CuPc, then it should be fine. It very much depends on what device structure you plan to do. CuPc itself can be used for a hole transport layer. However it may not be efficient as some metal oxides. Bear in mind that CuPc films can absorb the blue region of light.
Xuhua Wang i would like to say special thanks for your time, actually i want to improve the hole mobility and i am thinking about if embed C60 or hat cn then i can improve the hole mobility. so what's your opinion ?
Dear Mujahid
Firstly C60 is an electron dominiated materials. It is very often used for electron injection. Secondly, the energy levels of HOMO and LUMO are 5.55eV and 3.83eV. From energy alignment point view, it isn't good idea to do what you plan to do.
Hope it helps.
