Abstract
Overview and strategies for assessing chemical function, properties and application of naphthalene diimide (NDI) as an effective electron transport layer (ETL) in perovskite solar cells (PSCs).
Highlights
It is predicted that 2040 world energy demand will be around 18 million tonnes of oil equivalent (Mtoe), a 26% increase when compared to 2017.1 Within this prediction, the demand for electricity increases by 2.1% per year – which is double the rate of demand for all forms of energy.[2]
Within inverted p–i–n devices with P(NDI2DT-TTCN) and PCBM as electron extraction layers, the performance of devices based on P(NDI2DT-TTCN) signi cantly outperformed the devices based on PCBM alone (17.0 vs. 14.3%)
The results suggested that naphthalene diimide (NDI)-ID is a promising electron transport layer (ETL) material which can produce high-performing and thermally stable perovskite solar cells (PSCs) devices
Summary
It is predicted that 2040 world energy demand will be around 18 million tonnes of oil equivalent (Mtoe), a 26% increase when compared to 2017.1 Within this prediction, the demand for electricity increases by 2.1% per year – which is double the rate of demand for all forms of energy.[2]. His research interests are in the design and development of p-functional materials for organic and perovskite solar cells, chemical sensing, self-assembly, and supramolecular chemistry. Research on PSCs has intensi ed with the most recent reports of PCE of >25% challenging the status of silicon as the dominant semiconductor material for low-cost photovoltaics.[34,35] Importantly, stability of the highest efficiency devices (>24% PCE) in humid conditions without encapsulation has improved signi cantly over time.[36] It is evident that given the efficiency/fabrication cost ratio of PSCs, this technology is considered more viable for global future energy needs when compared with other third-generation technologies such as OPVs and DSSCs
