Unlike historical cinematic movements, these subgenres are the result of our techocentric culture and commercialism. In this respect these subgenres are less motivated by a collective ideology, but rather a cultural phenomenon resulting from increased access to popular culture, hypermedia devices, social media, and new marketing techniques. This paper investigates the displacement of traditional models of temporality through the metamorphosis of today＇s audiovisual culture, outlining the subject＇s embodiment of voyeurism and exhibitionism, ushering in a hyper-real era of self-myth making and consumption.展开更多

First, donor/acceptor(D/A) weight ratios were scanned,and then further optimization was performed by using different additives, i.e. 1,8-diiodooctane(DIO), diphenyl ether(DPE),1-chloronaphthalene(CN) and N-methyl-2-pyrrolidone(NMP), on the basis of best D/A ratio(1:1, w/w), respectively. Finally,the conventional or inverted device architectures with different buffer layers were employed to fabricate NF-PSC devices, and meanwhile, the morphology of the active layers was further optimized by controlling annealing temperature and time. As a result,a record efficiency of 11.3% was achieved, which is the highest result for NF-PSCs. It's also remarkable that the inverted NF-PSCs exhibited long-term stability, i.e. the best-performing devices maintain 83% of their initial PCEs after over 4000 h storage.展开更多
