Deliverable D3.3 – Wide band gap HTMs showing high thermal and chemical stability to guarantee their mechanical robustness (Public)Grant Agreement • February 1st, 2018
The importance to design and synthesize new hole transport materials (HTM) for application in perovskite solar cells (PSC) has been highlighted in two recent reviews on this topic.[1-2] The necessary properties of new HTMs are therein described as following. The HOMO level should be lower than the valance band of the perovskite light absorber and a sufficient hole mobility of around 10-3 cm2V-1s-1 is needed. A high glass transition temperature will be favorable to stabilize the amorphous phase beyond the temperature threshold in the device. If possible it is advised to avoid dopants or additives because they contribute to the degradation of the solar cells.[3] Herein, we will take these principles into account in order to design new classes of HTMs.
