As we know, when we prepare meso perovskite solar cells, we need calcinate mesoporous TiO2 at 500℃. And what is the suitable heating and cooling rate? Thank you in advance!
For heating mp-Tio2 multi-step heating was generally used.
Ramp (min) 5 15 5 5 5
Temp (ºC) 125 325 375 450 500
Hold (min) 5 5 5 15 15
The hotplate is left to cool slowly to 150 ºC before removing the samples. The resulting meso-TiO2 film look uniform and semi-transparent.
