Bulk-Heterojunction Organic Solar Cells: Five Core Technologies for Their Commercialization

by Hongkyu Kang, Geunjin Kim, Junghwan Kim, Sooncheol Kwon, Heejoo Kim, Kwanghee Lee

The past two decades of vigorous interdisciplinary approaches has seen tremendous breakthroughs in both scientific and technological developments of bulk-heterojunction organic solar cells (OSCs) based on nanocomposites of π-conjugated organic semiconductors. Because of their unique functionalities, the OSC field is expected to enable innovative photovoltaic applications that can be difficult to achieve using traditional inorganic solar cells: OSCs are printable, portable, wearable, disposable, biocompatible, and attachable to curved surfaces. The ultimate objective of this field is to develop cost-effective, stable, and high-performance photovoltaic modules fabricated on large-area flexible plastic substrates via high-volume/throughput roll-to-roll printing processing and thus achieve the practical implementation of OSCs. Recently, intensive research efforts into the development of organic materials, processing techniques, interface engineering, and device architectures have led to a remarkable improvement in power conversion efficiencies, exceeding 11%, which has finally brought OSCs close to commercialization. Current research interests are expanding from academic to industrial viewpoints to improve device stability and compatibility with large-scale printing processes, which must be addressed to realize viable applications. Here, both academic and industrial issues are reviewed by highlighting historically monumental research results and recent state-of-the-art progress in OSCs. Moreover, perspectives on five core technologies that affect the realization of the practical use of OSCs are presented, including device efficiency, device stability, flexible and transparent electrodes, module designs, and printing techniques.

Bulk-heterojunction organic solar cells based on solution-processable organic semiconductors enable completely new functionalities of being printable, portable, wearable, biocompatible, and attachable to any curved surfaces. The recent major advances in device efficiency and stability, flexible transparent electrodes, module design, and printing technologies for their commercialization are reviewed. The existing challenges and perspectives for these five core technologies are discussed.

Why You Should Stop Using Telegram Right Now

by manishs
Earlier this week, The Intercept evaluated the best instant messaging clients from the privacy standpoint. The list included Facebook's WhatsApp, Google's Allo, and Signal -- three apps that employ end-to-end encryption. One popular name that was missing from the list was Telegram. A report on Gizmodo sheds further light on the matter, adding that Telegram is riddled with a wide range of security issues, and "doesn't live up to its proclamations as a safe and secure messaging application." Citing many security experts, the report states:One major problem Telegram has is that it doesn't encrypt chats by default, something the FBI has advocated for. "There are many Telegram users who think they are communicating in an encrypted way, when they're not because they don't realize that they have to turn on an additional setting," Christopher Soghoian, Principal Technologist and Senior Policy Analyst at the American Civil Liberties Union, told Gizmodo. "Telegram has delivered everything that the government wants. Would I prefer that they used a method of encryption that followed industry best practices like WhatsApp and Signal? Certainly. But, if it's not turned on by default, it doesn't matter."The other issue that security experts have taken a note of is that Telegram employs its own encryption, which according to them, "is widely considered to be a fatal flaw when developing encrypted messaging apps." The report adds:"They use the MTproto protocol which is effectively homegrown and I've seen no proper proofs of its security," Alan Woodward, professor at the University of Surrey told Gizmodo. Woodward criticized Telegram for their lack of transparency regarding their home cooked encryption protocol. "At present we don't know enough to know if it's secure or insecure. That's the trouble with security by obscurity. It's usual for cryptographers to reveal the algorithms completely, but here we are in the dark. Unless you have considerable experience, you shouldn't write your own crypto. No one really understands why they did that."The list goes on and on.

Partially Single-Crystalline Mesoporous Nb2O5 Nanosheets in between Graphene for Ultrafast Sodium Storage

by Liu Wang, Xiaofang Bi, Shubin Yang
Thumbnail image of graphical abstract

Partially single-crystalline mesoporous Nb2O5 nanosheets with orthorhombic structure in between graphene are scalably fabricated via a simple nanocasting method. The well-designed architecture provides numerous open and short channels for fast diffusion of sodium ion and good electronic conductivity, resulting in an enhanced electrochemical performance and a favorable high-rate behavior for sodium storage.
