Special Issue Information

Dear Colleagues,

Organic solar cells are an important family of third generation photovoltaic technology and have stimulated extensive interest in the solar cell research community. Organic solar cells typically contain a mixture of an electron donor and an electron acceptor; either one or both of them are organic semiconductors (molecular or polymeric materials). These solar cells are light-weight, inexpensive, and compatible with large-scale roll-to-roll fabrication. Fueled by multidisciplinary research efforts, the past five years have seen a rapid advancement in their performance.

This Special Issue on “Organic Solar Cells” will discuss state-of-the-art topics concerning organic solar cells (e.g., the design and synthesis of organic semiconductors, material characterization, device photophysics and characterization, the design and fabrication of novel device architectures, etc.). The Special Issue will be of great interest to the organic solar cell research community. Your contribution to the issue will be greatly appreciated.

Title: Towards High Performance Organic Photovoltaic Cells: A Review of Recent Development in Organic Photovoltaics
Authors: Junsheng Yu *, Yifan Zheng and Jiang Huang
Affiliation: State Key Laboratory of Electronic Thin Films and Integrated Devices, School of Optoelectronic Information, University of Electronic Science and Technology of China (UESTC), Chengdu 610054, China; E-Mail: jsyu@uestc.edu.cn
Abstract:
Organic photovoltaic cells (OPVs) have been hot in trail during last decade due to their promising application in relieving energy pressure and environmental problem caused by the increasing combustion of fossil fuels. Lots of effort has been paid on understanding the photovoltaic mechanism, including evolving chemical structural motifs and designing device structures, leading to remarkable enhancement on the power conversion efficiency of OPVs from 3% to over 15%. In this brief review, the advanced progresses and the state-of-art performance of OPVs in very recent years are been summarized. Based on several latest developed approaches to accurately detect the separation of electron-hole pairs in femtosecond regime, the theoretical interpretation to exploit the comprehensive mechanistic picture of energy harvesting and carrier generation are discussed, especially for OPVs with bulk and multiple heterojunctions. Subsequently, the novel structural designs of device architecture of OPVs embracing external geometry modification and intrinsic structure decoration are presented. Additionally, some approaches to further increase the efficiency of OPVs are described, including thermotics and dynamics modification methods. Finally, this review highlights the challenges and prospects with the aim of providing a better understanding towards the high efficient OPVs.

Title: Synthesis of Thiophene- and 1,3,4-Thiadiazole-Based Donor-Acceptor Alternating Copolymers Suitable for Polymer Solar Cells with High Open Circuit Voltage
Author: Tomoya Higashihara
Affiliation: Department of Polymer Science and Engineering/Organic Device Engineering, Yamagata University, 4-3-16 Jonan Yonezawa, Yamagata-ken 992-8510 Japan; E-mail: thigashihara@yz.yamagata-u.ac.jp
Abstract: We report synthesis and characterization of 1,3,4-thiadiazole (TD)-containing p-conjugated alternating copolymers with thiophene-based donor units, such as thiophene, selenophene, thienothiophene, 3,3-didodecyl bithiophene and (E)-1,2-di-(3-dodecylthiophene)vinylene. The polymers were synthesized by stille coupling reaction between 2,5-bis(5’-bromo-3’,4’-didodecylthien-2’-yl)-1,3,4-thiadiazole and different distannyl compounds. Most of polymers show deep highest occupied molecular orbital energy levels due to the strong electron withdrawing ability of the TD unit. We also investigated the crystalline structures in the thin-films and their solar cell performances, showing the highest Voc value of 0.99 V.
