Efficient flexible polymer solar cells based on solution-processed reduced graphene oxide-Assisted silver nanowire transparent electrode Original Research Article Organic Electronics, Available online 3 August 2017, Pages Xiaoqin Zhang, Jiang Wu, He Liu, Jiantai Wang, Xiaofei Zhao, Zhiyuan Xie
Graphical abstractA kind of solution-processible transparent and conductive film consisting of rGO nanosheets and AgNWs is proposed to serve as the transparent electrode in flexible polymer solar cells. The hybrid film is prepared via layer-by-layer blade coating that is compatible to roll-to-roll manufacturing of polymer solar cells. The resultant polymer solar cells show similar photovoltaic performance but superior flexibility compared to those fabricated on the commercial ITO/PET substrate.Image 1
 | Adsorption of chloroform on N-doped and Al-doped graphene: A first-principle study Original Research Article Chemical Physics Letters, Available online 2 August 2017, Pages Y.L. Tian, J.F. Ren, W.W. Yue, M.N. Chen, G.C. Hu, X.B. Yuan
Graphical abstractDoped graphene acted as adsorbent to adsorb different molecules especially for pollutants has attracted many researcher's interests. In this article, we report that the sensitivity of graphene system to chloroform (CHCl3) could be enhanced to a higher level through N-doping and Al-doping based on density functional theory calculations (DFT). The adsorption energies, band structures, density of states (DOS) as well as differential charge density distributions are obtained. Our calculations reveal that there are higher charge transfer and smaller adsorption distance and bigger adsorption energy when CHCl3 is adsorbed on the surface of Al-doped graphene comparing with adsorptions for pristine graphene and N-doped graphene. The p-p orbital coupling between Al and Cl is stronger than those of C-Cl and N-Cl, which suggests that Al-doped graphene is more sensitive to the adsorption of CHCl3. Al-doped graphene is strongly reactive to CHCl3, which means it can be a good candidate for sensors or catalyst to detect and adsorb CHCl3.
