Processable Multipurpose Conjugated Polymer for Electrochromic and Photovoltaic Applications

Abstract

A benzotriazole and 3-hexylthiophene (3HT) bearing a donor-acceptor-donor (D-A-D) type conjugated polymer (PHTBT) was synthesized. The polymer is both p and n-dopable, fluorescent, soluble in common organic solvents, and processable. Electrochemical and spectroelectrochemical characterization of PHTBT and its photovoltaic performance in organic bulk heterojunction (BHJ) solar cells (SC) have been measured. Using PHTBT as donor material in BHJ solar cells resulted in increased open circuit voltage (V oc ) up to 0.85 V.

Miscibility of Polythiophene‐graft‐poly(methyl methacrylate) brushes with Poly(vinylidene fluoride): Morphology, Optical and Conductivity Properties

“…Poly(3-alkylthiophene) (P3AT) is an important member in the family of conjugated semiconducting polymers showing excellent optical and electronic properties which have been extensively studied for its applications in LEDs, [19,20] solar cells, [21,22] FETs, [23] etc. Our strategy is to incorporate these optical and conducting properties in a commodity polymer by producing miscible polymer blends.…”

“…This indicates that the electrochemical processes are not diffusion limited but are surface localized. 18,40 Optical Properties…”

“…The efficiency of bulk heterojunction solar cells depends on finding a balance between high interfacial area for effective photogeneration of charges and appropriate phase separation into continuous p-and n-type domains for effective charge transport towards the electrodes. Many research findings have been reported so far, describing the development of organic bulk heterojunction solar cells using polymer/fullerene, 10,12,[16][17][18] polymer/polymer, 19,20 and molecular blends. 21,22 The concept of hybrid solar cells using both organic and inorganic materials has been implemented to overcome certain drawbacks of organic semiconductors.…”

Передача электронного возбуждения из органической матрицы в нанокристаллы CdS, полученные методом Ленгмюра--Блоджетт

“…При этом метод ЛБ предполагает наличие твердой органической мат-рицы, которую при необходимости можно удалить [2]. Органические материалы в совокупности с полупровод-никовыми НК перспективны для создания солнечных батарей [3][4][5][6]. В таких структурах ключевыми являются процессы передачи электронного возбуждения из орга-нической матрицы в НК [6][7][8][9][10][11].…”
