I need to measure a parameter for evaluating Spiro layer performance, this parameter should be a quant, and just represent the Spiro performance, without Au.
Saeede,
the quality of Spiro-OMeTAD is determined by its use in the perovskite solar cells. This maerial is used as a a hole transport layer. Therefor it must has the following characteristics:
- high hole conductivity
- uniform thicness as a thin film layer
-free of pinholes and voids
-build an interface with the perovskite with little defects to reduce the recombination of the electron hole pairs at its interface.
The first property can be measured by sheet resistance of the spiro ome tad film while the second and third properties can be measured by microscopic inspection
The last property can be tested when depositing the film on perovskite and measure the lifetime of minority carriers in the perovskite with and without the spiro ome tad.
wish you success
