Team of 25 researchers from 7 institutes in Europe, USA and China (Linköping University, Sweden: Shula Chen, Xiao-Ke Liu, Liangqi Ouyang, Yingzhi Jin, Galia Pozina, Irina A. Buyanova, Weimin M. Chen, Olle Inganäs, Fengling Zhang, Feng Gao; Georgia Institute of Technology, USA: Zilong Zheng, Veaceslav Coropceanu, Jean-Luc Brédas; Chinese Academy of Sciences, China: Deping Qian, Huifeng Yao, Sunsun Li, Bowei Gao, Jianhui Hou; École Polytechnique Fédérale de Lausanne, Switzerland: Wolfgang Tress; Imperial College, UK: Thomas R. Hopper, Artem A. Bakulin; The Hong Kong University of Science and Technology, Hong Kong: Jing Liu, Shangshang Chen, He Yan; University of Cambridge, UK: Jiangbin Zhang) have come together to develop rules for designing high-efficiency organic solar cells. Their research, 'Design rules for minimizing voltage losses in high-efficiency organic solar cells', was published in Nature Materials. Lead researcher, Prof. Feng Gao of Linköping University, says, 'We have formulated some rational design rules to minimize energy losses in organic solar cells. Following these rules, we present a range of examples with low energy losses and high power conversion efficiencies.' The research provides two fundamental rules to minimize energy losses in organic solar cells - (1) Minimize the energy offset between donor and acceptor components. (2) Make sure that the low-gap component in the blend has a high photoluminescence yield. According to researchers, theoretically the limit for the fraction of the sun's energy that can be obtained in solar cells is around 33%, but laboratory experiments with silicon-based solar cells have achieved 25% at best. Prof. Olle Inganäs of Linköping University, 'But we now know that there is no difference - the theoretical limit is the same for solar cells manufactured from silicon, perovskites, or polymers.'

According to the latest research by Stanford University business academics, Prof. Navdeep Sahni and Prof. Harikesh Nair, people are very good at distinguishing native advertisements from digital content, but the ads still exert significant influence on shopping behavior. Native advertisements blend with the digital content and closely match style and layout of the surrounding media. Regulators are often concerned regarding their deceptive sponsorship disclosure and the resulting misguided purchases by consumers. Prof. Sahni says, 'Native advertising is a relatively new form of advertising. Advertisers and publishers have embraced this because of the rise in mobile browsing behavior, and because banner ads are hard to implement on mobile screens, and are known to be not very effective.' Professors developed a field experiment in which they manipulated how native advertising for specific restaurants appeared on a restaurant search mobile app, creating two 'extreme' ad presentation conditions (no-disclure and prominent-disclosure) to compare to a more typical native ad. The study examined differences in how over 200000 users responded to the varied presentations and found that responses to typical native ads were similar to those in the full-disclosure condition. Prof. Sahni adds, 'We found that people who respond to the ad can spot this kind of advertising in its typical format...The effect of advertising seems to happen through direct exposure and can result in conversion even if people don't click on the ad itself.' The study suggests that because consumers who are more likely to be affected by ads can identify typical native ads easily, making the ads more prominent is unlikely to change people's behavior. For consumers, implications of the study are that even in a time of advanced analytics, ad exposure continues to have a deeply subtle, and thus harder-to-quantify, effect. Read on...

Collaborative partnerships between local government, community, nonprofit organizations, academia and businesses can do wonders to enhance the various aspects of localities, cities and regions. An old factory site being rehabilitated as a business park in Lackawanna (New York, USA) is an example of sustainable redevelopment and the impact a local government can have on climate change. Erie County Executive Mark Poloncarz, Deputy Executive Maria Whyte and others officials visited Conrnell Universuty campus and discussed the redevelopment project with faculty and shared county initiatives focused on sustainability and economic growth, quality of life and building strong communities. Mr. Poloncarz says, 'Strong partnerships and sustainable practices are essential to progress, giving more people a say in their community and making responsible use of our resources to effect change that benefits generations yet to come.' Basil Safi, Executive Director of the Office of Engagement Initiatives at Cornell, says, 'The event was organized as a launching point to further community-engaged research and learning collaborations with Erie County', seeding ideas for potential projects involving Cornell students and faculty.' Initiatives for a Smart Economy (I4SE) is an economic development strategy Erie County enacted in 2013 and updated last year as I4SE 2.0. It contains 71 initiatives and is focused on inclusion and creating shared opportunities for all residents, to address persistent poverty and underemployment. Max Zhang, associate professor of mechanical and aerospace engineering at Cornell, says, 'I can envision that students team up with community partners to address specific challenges they are facing.' Rebecca Brenner, a lecturer at the Cornell Institute for Public Affairs, began a project in spring 2017 in Buffalo (NY) on improving communications during an emergency for that city's diverse, multilingual refugee population, and creating an emergency notification plan with nonprofit resettlement agencies as community partners. Erie County has about 300 current strategic initiatives led by county departments with community partners. They include fostering hiring of disadvantaged residents in high-poverty areas for construction jobs amid Buffalo's building boom; exploring the feasibility of a new convention center to spur tourism; creating an agribusiness park in rural southern Erie County; supporting health and human services agencies and energy programs targeting low-income households; and infrastructure and environmental remediation in county parks. Shorna Allred, associate professor of natural resources at Cornell, says, 'I was quite impressed and intrigued by what they are doing in Buffalo...We are similarly trying to bring together a partnership of people to work on sustainability issues across the city...'
