Ceramic macro-needles incorporation as reinforcement in commercial refractory castable was studied. Ceramic macro-needles (Ø2x20 mm) were made from kaolinite clay and gibbsite to obtain mullite as the main crystalline phase. Specimens with the ceramic reinforcement were evaluated by compression after being treated at two temperatures (815 and 1400 °C). The results were compared with those obtained using the same commercial concrete but reinforced with steel fibers and without reinforcement. Compression values presented by specimens with ceramic macro-needles were 74% and 50% higher than specimens with steel fibers after exposition to 815 and 1400 °C, respectively. Based on these results, it was established that ceramic macro-needles are a feasible solution to improve the mechanical resistance of castables exposed to high temperatures.

Resumo Células solares com emissor e face posterior passivada (PERC, passivated emitter and rear cell) vêm dominando o mercado fotovoltaico em razão de seu processo de fabricação ser compatível com as linhas industriais que vinham sendo utilizadas e pela produção de dispositivos de alta eficiência. Atualmente o silício tipo p é o mais utilizado pela indústria de células solares, mas o silício tipo n deve ganhar mercado nos próximos anos juntamente com o emprego de lâminas de espessura reduzida. O objetivo deste trabalho é apresentar uma revisão sistemática dos principais estudos na área de células solares base n, sendo elas do tipo PERC, PERT (passivated emitter-rear totally diffused) e TOPCon (tunnel oxide passivated contact), com ênfase para a abordagem de contatos seletivos, emissores seletivos e nos processos utilizados, bem como na análise de células solares de espessura reduzida em relação ao padrão da indústria atual.
