Superhydrophobic and antireflective nanograss-coated glass for high performance solar cells

Nano Research 2014年第5期7卷 670-678页

作者： Hyo Jin Gwon Yensil Park Cheon Woo Moon Sahn Nahm Seok-Jin yoon Soo Young Kim ho Won Jang Electronic Materials Research Center Korea Institute of Science and Technology Seou1136-791 Korea Department of Materials Science and Engineering Korea University Seoul 136-701 Korea School of Chemical Engineering and Materials Science Chung-Ang University Seou1156-756 Korea Department of Materials Science and Engineering Research Institute of Advanced Materials Seoul National University Seou1151-744Korea

We present a facile method for producing superhydrophobic nanograss-coated （SNGC） glass surfaces that possess both reduced reflectivity and self-cleaning properties at the air/glass interface. The refractive index of a CaF2 nanograss （NG） layer on a glass substrate, deposited by glancing angle vapor deposition, is 1.04 at 500 nm, which is the second-lowest value ever reported so far. The fluorinated NG layer gives rise to a high water contact angle （〉150°） and very efficient cleaning out of dust with water drops. Using the dual functionalities of the SNGC glass, we demonstrate superhydrophobic and antireflective organic photovoltaic cells with excellent power conversion efficiency.

Gastric cancer(GC)is a pervasive global malignancy with high mortality rates due to distant metastasis[1].GC metastasis can occur via hematogenous route,peri-toneal route,and specifically through ovarian spread in females[2].Among these,peritoneal metastasis is the most prevalent and challenging condition to treat[3].The Cancer Genome Atlas(TCGA)has uncovered four molec-ular subtypes of GC:microsatellite instability,Epstein-Barr virus-related,chromosomal instability,and genomically stable[4].
