Description
The project addresses these issues starting from the premise that coherent experimental and theoretical studies should be done using from the start cheap deposition techniques applicable on large areas (printing and sputtering). Besides allowing the scaling up, such techniques can be better controlled offering a better homogeneity in deposition than the spin-coating method. The overall objectives of the project are: A) to develop efficient, stable, reproducible standard and inverted perovskite solar cells and photovoltaic modules fabricated with affordable large area and environmental friendly technologies. B) to strengthen the knowledge base concerning the application of environmental technology; new knowledge will be acquired regarding how PSCs can be optimized for large scale applications and how can they be fabricated using environmentally friendly technologies with low carbon footprint. Specific objectives: O1 - understand the physical working principles of perovskite solar cells and find solutions to increase and stabilize the PCE while enlarging the area of the cells; O2 – reduce the amount of costly materials and toxic solvents used in the fabrication process of both standard and inverted PSC structures with other inexpensive and environmental friendly; O3 - stabilize the PCE performance of PSC via compositional engineering and proper replacements including the selective contacts; O4 - enhance the charge collection efficiency by optimizing interfaces between the layers in the cell; O5 - develop cheap large area fabrication technologies (printing and sputtering) for all the component layers in PSCs, standard and inverted structures; O6 - obtain efficient large area encapsulated PSCs and photovoltaic modules with PCE over 15%.
