How can I solve the problem of the high resistance of compact TiO2 and mesoporous TiO2 layers in perovskite solar cells?

I prepared perovskite solar cells (Glass/FTO/compact TiO2/mesoporous TiO2/Perovskite/spiro/Gold) inside dry air glove box. The best obtained efficiency was 6.6% which is very low. The resistance...
