Special Issue Information

Dear Colleagues,

We welcome you to contribute to this Special Issue, entitled “Perovskite Photovoltaics: From Materials to Device Applications.” Hybrid organic–inorganic perovskite solar cells have sparked significant research interest and have developed rapidly. In only a few years, the power conversion efficiency of perovskite solar cells has rapidly increased from the initial 3.8% to the certified 25.5%, indicating great potential for continuous improvement. The focus of this Special Issue will be on the technology of perovskite thin films and perovskite devices. Excellent perovskite film and crystal properties can effectively improve the device’s stability and energy conversion efficiency. This has been extensively used to improve device efficiency, particularly in interface passivation, crystal optimization, etc. The aim of this Special Issue is to present the most recent experimental and theoretical advances in the field through a combination of original research papers and review articles from leading groups worldwide.

In particular, the topics of interest include, but are not limited to, the following:

  • Interface passivation and crystal optimization of perovskite films;
  • Preparation of indoor perovskite photovoltaic devices;
  • Optimization process of lead-free perovskite devices;
  • Preparation of novel two-dimensional perovskite devices.

High-quality perovskite films (PFs) are crucial for achieving high-performance perovskite solar cells (PSCs). Herein, we report a dual-modification strategy via incorporating CsPbBr3 QDs into MAPbI3 perovskite bulk and capping the interface of the perovskite/hole transport layer (HTL) with phenylethylamine iodide (PEAI) to improve perovskite crystallinity and interface contact properties to acquire high-quality PFs with fewer defects. CsPbBr3 QDs promoted perovskite grain growth and reduced bulk defects, while PEAI surface modification passivated interfaces, improved hydrophobic properties, and prevented carrier recombination at the perovskite/HTL interface. Benefiting from growth control and the effective suppression of both bulk and interface carrier recombination, the resulting devices show a greatly improved photoelectric conversion efficiency (PCE) from 17.21% of the reference cells to 21.04% with a champion Voc of 1.15 V, Jsc of 23.30 mA/cm2, and fill factor (FF) of 78.6%. Furthermore, the dual-modification strategy endows PFs with promoted moisture tolerance, and the nonencapsulated PSCs retain 75% of their initial efficiency after aging for 30 days at 40% relative humidity and room temperature, which is significantly higher than the 59% value of the original PSCs. Good operational stability and the maintained efficiency of the target device over time suggest the potential for future commercialization. Full article

As a novel technology, perovskite solar cells (PSCs) have attracted worldwide attention due to their high photoelectric conversion efficiency (PCE) and low fabricating cost. Moreover, with the development of this technology, PSCs have achieved a great breakthrough in PCE. However, the heavy metal element Pb in PSCs does harm to human health and ecological environments, which restricts the further application of Pb-based PSCs. Under certain circumstances, the leakage of lead will cause serious pollution to the environment. The purpose of this review is to summary and discuss the way of lead leakage suppression. Among them, we pay more attention to the method of packaging technology, chemisorption procession and the limitations of each method. Finally, strategies of highly PCE and non-toxic perovskite devices are proposed. Full article
