Description

In the past decades, scientists have been attracted to focus on developingvarious clean and renewable energy technologies to fulfill the world energydemands. Among them, the photovoltaic (PV) technologies especially perovskitesolar cells (PSCs), have seen rapid progress in the optoelectronic applicationsdue to the excellent power conversion efficiencies (PCEs) and relatively low costas scalable and sustainable energy sources. During the course of developingeffective PSCs, various types of device architecture have been explored andreported. Nevertheless, one of the most prominent components that contributesfor the excellent performance of PSCs is the hole transporting material (HTM).The suitable HTM plays a significant role in suppressing charge recombinationand blocking electron carrier movement that lead the fabricated device to exhibitenhanced cell efficiency with higher Voc. Therefore, we continue our research onadvancement of various categories of photoelectric materials by investigatingnovel small organic salts and metal complexed molecules that can be preparedeasily and use them as efficient HTMs in PSCs. Along the way, we will refine ourdesign strategies of these HTMs to enhance power conversion efficiency andstability of the PSCs. We also will work with our collaborators to fine tune the cellarchitecture by using refined HTMs, changing cell layer configuration, employingadditives, or modifying perovskite composition to optimize and enhance deviceperformance.Our key research involves the rational design and preparation of photovoltaic materials with superb stabilities and photoelectric properties while developingefficient lead or lead free inverted PSCs. The current objective of this proposal isto develop novel photoelectric materials for inverted PSC applications and ourspecific aims are as the followings: 1) Preparation of HTMs for inverted PSCapplications using self-assembled monolayer, hydrophilic, and/or fluorinecontaining concepts, resulting in HTMs with/without salt configurations forefficiency comparison; 2) Employment of efficient methodologies to synthesizevarious metal complexed HTMs, especially, that can help to improve theformation and stability of perovskites in inverted PSCs; 3) Evaluation of cellperformance of inverted PSCs using prepared materials, and then refine therelated HTMs analogues based on the photovoltaic properties of these identifiedhits.; 4) Exploration of the critical and complete HTM structure and deviceproperties relationship by the investigation of the resulting data and thecorresponding cell interfacial mechanisms to generate patentable HTMs forinverted PSCs with marketable potential and offer valuable research insights atthe same time.
