Title in Portuguese
Fabricação e caracterização de uma célula solar à partir do polímero poli (N-vinilcarbazol) - PVK dopado com perclorato de lítio.
Keywords in Portuguese
Células solares (fabricação)
Conversão de energia elétrica
Polímeros (materiais)
Abstract in Portuguese
O objetivo do trabalho foi demonstrar que o polivinilcarbazol (PVK) dopado com Perclorato de Lítio (LiClO4) pode converter energia luminosa em energia elétrica. Esse material polimérico possui a propriedade de absorver e gerar pares de elétron-lacunas fornecendo uma corrente elétrica quando exposto à iluminação. Para essa finalidade foi construído um dispositivo (célula solar) com a seguinte estrutura: vidro / ITO / a-Si:H (p) / polímero PVK / µ-Si:H (n) / Al, tendo o PVK dopado como camada ativa. O estudo proposto, dessa maneira, teve como finalidade: pesquisar, desenvolver, fabricar e caracterizar esse dispositivo, analisando suas características elétricas e ópticas, sua eficiência de conversão (rendimento) e outros fatores relacionados ao seu desempenho e do processo de fabricação.

Abstract in English
The objective of this article is to demonstrate that the Poly(N-vinylcarbazole) PVK dumped with lithium perchlorate (LiClO4) can transform solar energy to electrical energy. This polymer material has the property of absorbing and generate electron hole pairs, providing an electric current when exposed to enlightenment. To achieve that, a solar cell has been constructed with the follow structure: glass structure/ITO/a-Si:H (p)/polymer PVK/µ-Si:H (n)/Al, with the PVK working as active layer. This proposed article had the objective to research, develop, construct and characterize this device, analyzing its electrical and optical characteristics, efficiency and other topics related to its development and construction process.
