“…Segundo Gul et al (2016), metade das empresas que fabricam essas placas, estão localizadas na China e na Alemanha, e desenvolvem materiais com eficiências que variam de 15,0 à 16,9%; sendo que a maior eficiência em módulos comerciais é de 16,9%, alcançadas por uma empresa de Taiwan (T10 da Neo Solar Power Corporation).Os módulos de índio disseleneto de cobre (CIS), que também podem apresentar o Gálio em sua composição (CIGS), (WALTER et al, 1997), pode chegar a uma eficiência 18,8%, como acorrido em um teste realizado em dezembro de 2013 (GUL, 2016).…”

O aumento da demanda de energia elétrica no Brasil para os próximos 10 anos é de 4,25% ao ano, demandando assim uma expansão do sistema de 3,8% a.a., com previsão de crescimento médio da carga de energia de 2.900 MW ano-1. O aumento da demanda, somado aos recorrentes déficits hídricos em várias usinas hidrelétricas e a lentidão da expansão do sistema de geração sustentável, acarretará aumento do consumo de energia gerada por meio de combustíveis fósseis. Neste contexto, a implantação de sistemas híbridos (energia elétrica fotovoltaica e aquecedor de água solar) integrados a rede de distribuição de energia elétrica, apresenta-se como uma alternativa para reduzir essa demanda, com um potencial de produção média de cerca de 3.000 MWh mês-1 a cada 10 mil casas, que corresponde a energia produzida por uma pequena central hidrelétrica de 6 MW (FC = 0,7) de capacidade instalada. Palavras-chave: energia solar, aquecimento de água, matriz energética. Integration of photovoltaic systems and water heater solar roofs in residential ABSTRACT: The increase in electric energy demand in Brazil for the next 10 years is 4.25% per year, thus requiring an expansion of the system of 3.8% per year, with an expected average energy load growth of 2,900 MW year-1. The increase in demand coupled with the recurring water deficits in several hydroelectric plants and the slow expansion of the sustainable generation system will increase the consumption of energy generated by fossil. In this context, the deployment of hybrid systems (photovoltaic electricity and solar water heater) integrated electrical power distribution network, presents itself as an alternative to reduce this demand, with an average production potential of about 3,000 MWh month-1 every 10,000 homes, equivalent to the energy produced by a small hydroelectric power plant of 6 MW (FC = 0,7) of installed capacity.

“…The diode ideality factor A of around 1.6 reveals that the carrier recombination near the junction area (space-charge region) was relatively dominant. The space-charge region (SCR) recombination has been reported as the primary recombination mechanism for the CIGS solar cells in the literature [46,63,64]. The diode current based on the SCR recombination path can be described by [65]…”

Cu(In,Ga)Se 2 (CIGS) films were prepared by a single-stage co-evaporation process at Se flux rates of 10 Å s −1 , 20 Å s −1 , and 30 Å s −1 and substrate temperatures ranging from 400 °C to 500 °C. The flux rates of the Cu, In, Ga, and Se were kept constant throughout each deposition of the films. The grain sizes, surface morphologies, and crystallinity of the CIGS films improved with increasing substrate temperatures or Se flux rates. The causes of the formation of voids on the surface of CIGS films deposited with a low Se flux rate of 10 Å s −1 at substrate temperatures of 475 °C and 500 °C were addressed. The higher Se flux rates of 20 Å s −1 and 30 Å s −1 repressed the formation of voids for the CIGS films deposited at the relatively higher substrate temperatures of 475 °C and 500 °C. The conversion efficiencies of CIGS solar cells were significantly improved by increasing the substrate temperatures or the Se flux rates, largely contributed from the enhancement of the open-circuit voltage and fill factor because of the restraint of the carrier recombination. The short-circuit current densities were slightly enhanced by the increment of the substrate temperatures or the Se flux rates, resulting from the improved crystalline quality of the CIGS films. Moreover, the EQE results suggest that the effective carrier-diffusion lengths of the films deposited at the relatively high substrate temperatures were increased, leading to the enhancement of the short-circuit current density. The efficiencies of CIGS solar cells prepared with a Se flux rate of 10 Å s −1 improved from 10% to 12.4% when the substrate temperatures increased from 400 °C to 500 °C. The efficiencies of cells deposited at the substrate temperature of 500 °C improved to 15.4% as the Se flux rates increased from 10 Å s −1 to 30 Å s −1 .

This work concentrates on the rewiew of the study of the photoelectrical phenomena of thin films for solar cells and also show the search of a new physical effects, which may be the basis for the development of new technologies, diagnostic methods, new types of photoconverters, and devices on these multinary semiconductors.Solar cells which based on silicon or binary III-V semiconductor compounds and their solid solutions successfully fulfilled their role as the first energy sources in outer space in the 1950s-1990s. Since 1997, technological development has been carried out for amorphous Si, CdTe thin film polycristal and CuInSe 2 (CIS) solar cells in the thin film solar cell family. Thin film solar cells based on CuInSe 2 and the related materials heretofore have been studied only for the aims of creating efficiencies. Complex physical and technological studies of the thin film solar cells on the basis chalcogenide chalcopyrite materials have made it possible to create devices with high radiation hardness and efficiencies as high as 18% [1][2][3][4]. At the same time, basic studies aimed to speed up film deposition is conducted from the aspect of material and substrate technologies for further cost reductions. For CIS solar cells research and development efforts continue to establish both element technologies necessary for the improvement in product quality and efficiency and large-area film fabrication technologies as essential part of the solar cell production process.
