고분자태양전지는 용액공정에 의한 생산이 가능하여, 경량, 저비용, 기계적 유연성 및 고효율과 같은 많은 이점이 있다. 이들은 지난 수십 년 동안 많은 관심을 끌어왔다. 공액 고분자 전해질(conjugated polymer electrolyte, CPE) 및 비공액 고분자 전해질(non-conjugated polymer electrolyte, NPE) 재료는 기존의 금속 산화물 중간층과 관련된 일반적인 약점(전하 수집능력 저하 및 금속/고분자 계면에서의상용성 저하 등)을 극복하기 위해 사용되었다. 그러나 CPE의 합성은 매우 복잡한 합성과정이 필요하며, 대량합성이 어려운 단점이 있다. 따라서 상대적으로 합성이 용이한 NPE를 개발 혹은 기존에 개발되어 있는 NPE를 이용하면 보다 쉽게 단점을 극복할 수 있다. 이온 그룹이 포함되어 있는 경우 NPE는 특히 고분자 태양전지를 구현함에 있어 많은 이점을 제공할 수 있으며, 이에 본 총설에서는 그 동안 개발 혹은 응용되었던 NPE에 대한 내용을 다루었다.

Abstract ▼ AI-Helper

Polymer solar cells have attracted extensive attention over the past decade due to their benefits, such as good solution-process-ability, light weight, low-cost, mechanically flexibility, and high efficiency. Conjugated (CPE) and non-conjugated (NPE) polyelectrolyte materials have been employed to avoid the typical weaknesses associated with conventional metal oxide interlayers. However, the application of CPEs is more complicated than that of NPEs because the synthesis procedures are complicated. NPEs containing charged ion groups can provide numerous benefits for renewable energy applications. Especially when implemented in polymer solar cells.

문제 정의

The final chapter examines the emerging applications of NPEs in organic optoelectronic devices and details how the NPE molecular structure dictates the most relevant properties of these devices. The readers are encouraged to read this review for basic information and descriptions of the current work in this field of renewable energy research.
Various NPEs have attracted significant attention due to their more facile synthesis compared to that of CPEs, and their unique properties can be advantageous to PSC applications. This article has reviewed the design and synthesis pathways of NPEs, their electronic properties, and their application in PSCs. Alongside the development of NPEs, the structure-property relationships of NPEs and their influence on PSC performance warrant further investigation.
When PEIH⁺BIm₄^- was applied as the interfacial layer, the PCE was observed to increase as the interlayer thickness increased. This study demonstrates that using a variety of organic cathode interlayers in organic solar cells can result in unique properties emerging from each interlayer, which can lead to specific applications in the device field[43].

제안 방법

In the second section, we discuss the electronics properties of NPEs and present a comprehensive account of their application in energy fields, particularly as PSCs. The final chapter examines the emerging applications of NPEs in organic optoelectronic devices and details how the NPE molecular structure dictates the most relevant properties of these devices. The readers are encouraged to read this review for basic information and descriptions of the current work in this field of renewable energy research.
This review primarily focuses on the fundamentals and applications of NPEs and is organized as follows: First, we provide a general background on NPEs and introduce the syntheses of various NPE structures. This section also discusses how to prepare the main types of CPE structures and extensively compares the different synthetic approaches.
X-ray photoelectron spectroscopy (XPS) was used to analyze the structure of PVPy-ZW and its addition to ITO or ITO/ZnO surfaces, which showed potential for being able to adjust the work function of the electrodes. This study also conducted Kelvin probe microscopy (KPM) measurements to examine the work function shifts of ZnO and ITO surfaces in the presence of PVPy-ZW. The work function shifts of the electrodes treated with NPE was 4.
The electronic properties of PVPy-ZW were examined for its application as a cathode buffer layer in organic photovoltaic devices, which were fabricated with either modified or standard PSCs.

성능/효과

In 2016, Shin and co-workers[66] reported another example of the application of NPEs to modify cathode buffer layers. The polyelectrolyte PVPy-F was easily synthesized from poly(4-vinyl pyridine), and upon its implementation in the device an improved PCE of 3.46% was obtained (Table 1).
