SusMat, Journal Year: 2022, Volume and Issue: 2(3), P. 243 - 263

Published: March 9, 2022

Abstract Organic solar cells (OSCs), benefiting from their significant advantages, such as light weight, flexibility, low cost, and large area manufacturing adaptability, are considered promising clean energy technologies. Currently, the power conversion efficiency (PCE) of state‐of‐the‐art OSCs has reached over 18% through materials device engineering. Specifically, cathode engineering with interlayer (CIMs) is an important strategy to improve PCEs stability OSCs. Among various CIMs reported in literature, perylene diimides (PDIs) more appropriate for working interlayers owing distinct advantages suitable levels, high electron affinity, mobility, facile modification. In this review, mechanism concisely summarized, recent research progress on PDI derivatives systematically reviewed. Finally, prospects suggestions provided development PDI‐based practical applications.

Polymer‐Coated Organic Crystals with Solvent‐Resistant Capacity and Optical Waveguiding Function

Angewandte Chemie International Edition, Journal Year: 2021, Volume and Issue: 60(20), P. 11283 - 11287

Published: March 10, 2021

Abstract Recently, luminescent organic crystals have been widely studied as new optoelectronic materials. However, corrosion and dissolution of by solvents always a great challenge for the application in various fields. In this work, we propose general method fabricating solvent‐resistant coating to prevent from being corroded or dissolved solvents. The coatings involved layer‐by‐layer assembly poly(diallyldimethylammonium) (PDDA) poly(styrenesulfonate) (PSS) onto crystals, followed immersing coated into polyvinyl alcohol (PVA) aqueous solutions 2 minutes. can remain intact over 24 h common without damaged even insoluble dichloromethane 5 days. Moreover, thin transparent little effect on optical properties which still excellent waveguide performance with coatings.

Significant Photostability Enhancement of Inverted Organic Solar Cells by Inserting an N-Annulated Perylene Diimide (PDIN-H) between the ZnO Electron Extraction Layer and the Organic Active Layer

ACS Applied Energy Materials, Journal Year: 2020, Volume and Issue: 3(12), P. 11655 - 11665

Published: Nov. 24, 2020

We investigate the effect of adding an N-annulated perylene diimide dye with a pyrrolic NH functional group (PDIN-H) onto electron extraction layer (EEL) in bilayer configuration (ZnO/PDIN-H) on photostability inverted organic solar cells (OSCs). To do so, we insert thin PDIN-H between ZnO and bulk heterojunction (BHJ) active layer. Results show that under prolonged ultraviolet (UV) irradiation, ZnO/PDIN-H EEL exhibit substantially higher compared to reference only ZnO, leading respective T80 values ≳780 h versus ∼124 h, where is time before power conversion efficiency (PCE) decreases 80% its initial value. The PCE arises primarily from more stable open-circuit voltage (Voc) fill factor (FF) UV stress. Changes dark reverse current characteristics Voc stability acquired upon top mainly due ability ITO/ZnO/PDIN-H contact maintain blockage hole injection even after Analysis dependence light ideality factors verifies inserting prevents significant extent UV-induced surface recombination observed at ZnO/active-layer interface, thus enhancing cells' photostability. hole-only devices photoelectron spectroscopy reveal passivation defects by primary origin suppressing thereby increasing findings provide not critical insights into substantial role collection photodegradation OSCs but also strategies control them can be utilized well beyond specific material system being studied here.

Journal of Chemical Education, Journal Year: 2024, Volume and Issue: 101(7), P. 2765 - 2778

Published: June 27, 2024

Green chemistry as a subject has yet to become standard practice in schools, particularly the secondary curriculum. While there are initiatives incorporate sustainability principles education, Philippines lags behind this trend. Thus, study aimed investigate awareness, attitude, knowledge, perception, and views of Senior High School (SHS) science teachers (n = 43) toward green education. Through mixed-methods design, assessed need integrate into By merging quantitative qualitative results, revealed that (1) is increase awareness chemistry; (2) promoting positive attitude can help integration (3) should be equipped with content pedagogical knowledge deliver theories principles; (4) although implementation perceived challenge, potential solutions overcoming these barriers. These findings aim provide baseline data for effective teacher development program will capacitate Filipino concepts classroom.
