Low‐light applications provide an exciting market opportunity for organic solar cells (OSCs). However, so far, studies have only considered OSCs of limited commercial viability. Herein, the applicability of a fully‐scalable, flexible, inverted non‐fullerene acceptor (NFA) containing OSC is demonstrated by showing its superior performance to silicon under low‐light, achieving 40 µW cm−2 maximum power output at 1300 lx illumination. The effect of parasitic resistance and dark current on low‐light performance are identified. Furthermore, an atmosphere sensitive light‐soaking (LS) effect, critical for low‐light performance and resulting in undesirable S‐shaped current‐voltage characteristics, is analyzed. By employing different interlayers and photoactive layers (PALs) the origin of this LS effect is identified as poor electron extraction at the electron transport layer (ETL)/PAL interface when the common ETL ZnO is used. Two strategies are implemented to overcome the LS effect: replacement of ZnO with SnO2 nanoparticles to reduce ETL sub‐gap electron trap states or tuning the NFA energy levels to optimize interfacial energetics. Finally, the commercial viability of these LS‐free devices is demonstrated by fabricating fully printed large‐area modules (21.6 cm2) achieving a maximum power output of 17.2 µW cm−2, providing the most relevant example of the currently obtainable performance in commercial low‐light OSCs.

Fully printed perovskite solar cells (PSCs) were fabricated in air with all constituent layers, except for electrodes, deposited by the blade coating technique. The PSCs incorporated, for the first time, a nanometer-thick printed Bathocuproine (BCP) hole blocking buffer using blade coating technique and deposited at relative humidity up to 50%. The PSCs with a p-i-n architecture (Glass/Indium tin oxide(ITO)

RESUMOA partir da prerrogativa de que os estudos de recepção/consumo devem considerar o processo comunicacional sempre como uma relação, priorizamos, neste trabalho, investigar os usos e apropriações do Twitter e os sentidos circulantes na hashtag #primeiroassedio. Fomentada por um coletivo feminista, a hashtag foi uma reação a diversos comentários de caráter pedofílico divulgados na internet sobre uma participante de 12 anos de um popular reality show brasileiro. O caso nos mostra como a circulação de comentários sobre a programação televisiva nas redes sociais digitais pode motivar o debate e proporcionar visibilidade a questões sociais, como a cultura do assédio. Palavras-chave:Twitter, circulação, cultura do assédio. ABSTRACTFrom the prerogative that the studies of reception and consumption must always consider the communication process as a relation, we've prioritized this paper to investigate Twitter's uses and appropriations and current directions in the #primeiroassedio hashtag. Fomented by a collective, to bring attention to the harassment culture, especially the pedophile culture, through reports of the first harassment suffered by women after the public case involving a 12-year girl participant of a popular Brazilian reality show was disclosed. The case shows how the circulation of comments on the television programming in digital social networks can encourage debate and provide visibility to social issues, such as the harassment culture.
