In-depth analysis of chloride treatments for thin-film CdTe solar cells

Nature Communications, Published online: 24 October 2016; doi:10.1038/ncomms13231

High performance CdTe thin film solar cells typically require a chloride activation treatment. Here, Major et al. show that the main effect of the most effective chloride-based treatments is chloride accumulation at grain boundaries and that it results in improved open circuit voltages.

Using o-Chlorobenzaldehyde as a Fast Removable Solvent Additive during Spin-Coating PTB7-Based Active Layers: High Efficiency Thick-Film Polymer Solar Cells

by Jinxiang Chen, Lianjie Zhang, Xiaofang Jiang, Ke Gao, Feng Liu, Xiangjun Gong, Junwu Chen, Yong Cao
Thumbnail image of graphical abstract

o-Chlorobenzaldehyde (CBA) is a derivative of chlorobenzene (CB). The boiling point of CBA is 212 °C, much lower than 332 °C for 1,8-diiodooctane (DIO). With CBA as solvent additive in CB host solvent, CBA could be fast removed during spin-coating 100, 200, and 300 nm thick thieno[3,4-b]thiophene/benzodithiophene polymer (PTB7):[6,6]-phenyl C71-butyric acid methyl ester (PC71BM) active layers, achieving power conversion efficiencies of 9.11%, 8.24%, and 7.11%, respectively, much higher than 7.53%, 5.71%, and 4.93% for corresponding DIO control devices with vacuum drying.

Using small amounts of solvent additives during fabrication of organic solar cells has been formerly shown to render a facile approach for improving the performance by tuning the active layer nano-morphology. However, in certain cases, solvent additives are now found to accelerate device degradation. This is reported by Peter Müller-Buschbaum and co-workers in article number 1600712.

Transparent conducting oxide-free nitrogen-doped graphene/reduced hydroxylated carbon nanotube composite paper as flexible counter electrodes for dye-sensitized solar cells

Publication date: 1 December 2016
Source:Journal of Power Sources, Volume 334
Author(s): Jindan Zhang, Mei Yu, Songmei Li, Yanbing Meng, Xueke Wu, Jianhua Liu
Three-dimensional nitrogen-doped graphene/reduced hydroxylated carbon nanotube composite aerogel (NG/CNT-OH) with unique hierarchical porosity and mechanical stability is developed through a two-step hydrothermal reaction. With plenty of exposed active sites and efficient multidimensional transport pathways of electrons and ions, NG/CNT-OH exhibits great electrocatalytic performances for I/I3 redox couple. The subsequent compressed NG/CNT-OH papers possess high electrical conductivity and good flexibility, thus generating high-performance flexible counter electrodes (CEs) with transparent conducting oxide free (TCO-free) for dye-sensitized solar cells (DSSCs). The flexible NG/CNT-OH electrodes show good stability and the DSSCs with the optimized NG/CNT-OH CE had higher short-circuit current density (13.62 mA cm−2) and cell efficiency (6.36%) than DSSCs using Pt CE, whereas those of the DSSCs using Pt CE were only 12.81 mA cm−2 and 5.74%, respectively. Increasing the ratio of hydroxylated carbon nanotubes (CNT-OH) to the graphene oxide (GO) in the reactant would lead to less content of doped N, but better diffusion of electrolyte in the CEs because of more complete GO etching reaction. The design strategy presents a facile and cost effective way to synthesis three-dimensional graphene/CNT composite aerogel with excellent performance, and it can be potentially used as flexible TCO-free CE in other power conversion or energy storage devices.
