Researchers led by Prof. GE Ziyi at the Ningbo Institute of Materials Technology and Engineering (NIMTE) have introduced a groundbreaking multifunctional additive to enhance the efficiency and stability of inverted perovskite solar cells (PSCs).
Innovative Solution for Solar Cell Enhancement
Published in Angewandte Chemie International Edition, the study highlights the development of potassium (4-tert-butoxycarbonylpiperazin-1-yl) methyl trifluoroborate (PTFBK) as an additive. This compound effectively addresses defects and facilitates charge carrier transport in perovskite films, crucial for enhancing PSC efficiency and stability.
Addressing Limitations in Perovskite Solar Technology
Despite their promising properties, PSCs have faced challenges related to power conversion efficiency (PCE) and long-term stability. Defects in perovskite films contribute to these limitations, hindering commercialization efforts.
Synergistic Effects Lead to Remarkable Results
The integration of PTFBK into perovskite precursor solutions offers multiple benefits, including defect passivation and improved carrier extraction. This leads to the formation of high-quality perovskite films with larger grain size, enhancing overall cell performance.
Future Implications and Support
This breakthrough not only improves PSC efficiency but also enhances their durability and flexibility, paving the way for their widespread adoption in various applications. The study received support from prominent funding bodies, underscoring the significance of this research in advancing solar energy technologies.
