Job Details
In this context, it was recently shown in the framework of our LIA jointlab 'Next-PV' that combining a porous TiO2 layer with the introduction of K+ cations within the perovskite enables to solve hysteresis issues. In addition, the use of functional polyvinylcarbazoles and ionic liquid polymers in the hole-transporting layer has led to enhanced performance and stability. Nonetheless, the origin of the improvements has not been rationalized yet. As a consequence, the objective of this project is the thorough characterization of the different interfaces present in these devices by exploiting the facilities offered by the ELORPrintTec facility.
The working plan will consists in the following steps: i) Fabrication and characterization of state of the art perovskite solar cells involving functional polyvinylcarbazoles and ionic liquid polymers; ii) Characterization of the morphology and electronic properties of the perovskite layers (SEM, UV-visible, fluorescence, UPS); iii) Characterization of the atomic composition and band alignment at the different interfaces present in the devices by UPS, XPS and IPES analyses: a) TiO2/lead perovskite; b) lead perovskite/hole transporting layer; c) hole-transporting layer/gold.
