What problem is addressed by the project?
The aim of the project carried out by the Military Institute of Engineer Technology was to achieve low-cost, air- and heat-stable new organic compounds for use as hole transport layers (HTMs) in perovskite solar cells. Symmetrical and asymmetrical imines have been proposed as organic compounds, obtained by a one-step condensation process of an aldehyde with amines/diamines, where only water is a by-product of the reaction. The proposed method of imine synthesis can be described as environmentally friendly also due to the fact that no inorganic catalysts are used.
An additional advantage of the proposed solution is the reduction of the manufacturing cost of the HTM layer, currently based mainly on the commercial compound Spiro-OMeTAD (about 494 Euro/gram), whose cost is about 7.6 times higher than that of the proposed imine (65 Euro/g).
Furthermore, in order to minimise solar cell manufacturing costs, a thermal imaging camera was proposed and successfully applied to the fabricated layers to analyse surface defects and electrical and thermal parameters crucial to the design of efficient perovskite solar cells.
Advantages of the proposed imine-based solution with respect to Spiro-OMeTAD:
price, efficiency (PCE), durability and environmental performance.
