Project Description

The aim of the project is to develop methodologies and protocols for the production and characterisation of fully printed and efficient FPSC based on hybrid perovskite with different compositions and with a printed top electrode based on inexpensive conductive materials.

Project Relevance

Perovskite solar cells (PSCs) are one of the most promising photovoltaic devices for generating alternative green energy from the sun. Perovskites offer unique advantages over classical inorganic semiconductor materials, such as low-temperature solution processing and the use of various deposition techniques to print perovskite thin films on different types of (rigid or flexible) substrates. These features of perovskites may enable large scale production of cost effective and fully printable flexible PSEs (FPEs). The project focuses on an experimental study of processes for the fabrication of partially and fully printed CPSEs on the surface of plastic substrates by the slit-coating method. The objectives of the project are to optimise the printing process of SPSEs, analyse physico-chemical properties of printed thin films of functional layers of SPSEs and investigate photovoltaic properties of the manufactured devices. The results of the project will contribute to the progress of key basic and applied research in PSPE, will play an important role in mastering the necessary skills and know-how for fabrication and research of flexible and printed perovskite-based optoelectronic devices, and in the development of a modern laboratory for high-level research in flexible electronics.

Project Impact

- Optimal parameters were determined for the printing of functional HPSE layers on the surface of PET/ITO substrates using the slit-coating method.
- The morphological, structural and optoelectronic properties of the obtained thin films were analysed.
- Printed PGEs using different ETLs (SnO2, ZnO and PCBM) and HTLs (P3HT, Spiro-OMETAD and PTAA) in combination with MAPbI3 pervovskite were fabricated.
- The photovoltaic properties of the obtained devices were studied.
- Experimental data were analysed and the effect of different ETL and HTL materials on the performance of the devices was investigated.
- Experimental HTL devices with efficiencies of ≥ 8% were obtained.
- Work is underway to investigate perovskites of complex composition, optimal for printing the photo-active layer of GPSEs.
- Work will be carried out to determine the optimum parameters for printing perovskites of complex composition by the slit coating method, and the physical and chemical properties of the thin films obtained will be investigated.
