چکیده
A series of low bandgap indacenodithiophene polymers is purified by recycling SEC in order to isolate narrow polydispersity fractions. This additional purification step is found to have a significant beneficial influence on the solar cell performance and the reasons for this performance increase are investigated.

Synthesis of thienoselenadiazole-containing conjugated copolymers and their application in polymer solar cells
INTRODUCTION In recent years, polymer solar cells (PSCs) have attracted great attention due to the energy crisis all over the world. Compared with inorganic solar cells, PSCs have many advantages, such as light weight, solution processability, mechanical flexibility and low cost.1 The stateof-the-art of PSCs are based on a fullerene-derivative acceptor, such as [6,6]-phenyl-C61-butyric acid met...
متن کاملWide Band Gap Polymer Based on Indacenodithiophene and Acenaphthoquinoxaline for Efficient Polymer Solar Cells Application
A new wide band gap polymer PIDT-AQx with indacenodithiophene (IDT) as the electron-rich unit and acenaphthoquinoxaline (AQx) as the electron-deficient unit has been designed and synthesized. The optical band gap of PIDT-AQx was 1.81 eV with a HOMO energy level of −5.13 eV. Polymer solar cells with the blend of PIDT-AQx/PC71BM as the active layer achieved a power conversion efficiency (PCE) of ...
متن کاملThe Application of Wide Band Gap Conjugated Polymers in Single Junction Polymer Solar Cells
In this research, a new phenanthroline derivative was synthesized and characterized on purpose to polymerize the monomer via a Stille-polymerization with different electron donating moieties leading to a range of new wide band gap polymers. The novelty in this monomer would be the long side chains in order to ensure the solubility of the entire polymer. Hence there would be no necessity for the...
متن کاملAcid azo dyes for efficient molecular photovoltaic: study of dye-sensitized solar cells performance
In this paper we sensitized three free-metal azo days Dye 1, Dye 2 and Dye 3 based on 1,8-naphthalimide with n-propyl as the electron donor group. We used sulfonic acid and hydroxyl substituents as the electron acceptor anchoring group in synthesized dyes. The proposed dyes were sensitized from acenaphthene as the starting material by standard reactions and characterized by different techniques...
متن کاملDevelopment of novel conjugated donor polymers for high-efficiency bulk-heterojunction photovoltaic devices.
Solar cells are one attractive method for harnessing inexhaustible clean energy from the sun. Organic photovoltaic technology is emerging as a potential competitor to silicon-based photovoltaic cells (PVCs), and their power conversion efficiencies (PCE) can now exceed 6%. Polymeric bulk-heterojunction (BHJ) PVCs, whose photoactive layer is composed of a blend of bicontinuous and interpenetratin...
