“…The physical principles of losses in thin film solar cells and efficiency enhancements methods are addressed by Dhankhar et al [106], where, in general, the investigations on thin film solar cells, including e.g., both amorphous and crystalline silicon, represent an important research field [106][107][108][109][110]. Studies on semi-transparent photovoltaics have also been conducted [28,103,[111][112][113][114][115], likewise life cycle assessments (LCA) of photovoltaics [20,55,116,117].…”

Abstract:Building integrated photovoltaics (BIPV) offer an aesthetical, economical and technical solution to integrate solar cells harvesting solar radiation to produce electricity within the climate envelopes of buildings. Photovoltaic (PV) cells may be mounted above or onto the existing or traditional roofing or wall systems. However, BIPV systems replace the outer building envelope skin, i.e., the climate screen, hence serving simultanously as both a climate screen and a power source generating electricity. Thus, BIPV may provide savings in materials and labor, in addition to reducing the electricity costs. Hence, for the BIPV products, in addition to specific requirements put on the solar cell technology, it is of major importance to have satisfactory or strict requirements of rain tightness and durability, where building physical issues like e.g., heat and moisture transport in the building envelope also have to be considered and accounted for. This work, from both a technological and scientific point of view, summarizes briefly the current state-of-the-art of BIPV, including both BIPV foil, tiles, modules and solar cell glazing products, and addresses possible research pathways for BIPV in the years to come.

“…Os compostos calcopiriticos são completamente miscíveis entre si, quimicamente está-veis e variando-se as proporções desses elementos, obtêm-se propriedades semicondutoras, que absorvem intensamente a radiação solar [3].…”

“…Apresenta-se como um semicondutor do tipo N ou P, dependendo da estequiometria utilizada, possui boa estabilidade térmica e elétrica, sendo atrativo para aplicação em conversão fotovoltaica e um dos materiais semicondutores mais promissores utilizados em células solares nos últimos anos para aplicação como camada absorvedora na forma de filmes. Células solares baseadas em CIS já demonstraram eficiência de 19,9% [3,4].…”

RESUMOOs filmes Cu 0,6 In 0,4 Se 2 foram depositados em substrato de vidro pela técnica de spray-pirólise, para utilização como camada absorvedora de células fotovoltaicas. Foram adotados os seguintes parâmetros de deposição: temperatura de substrato entre 250 e 400ºC, fluxo da solução precursora de 1 mL/min e tempo de deposição de 30 min. As propriedades estruturais, elétricas, morfológicas e óticas dos filmes preparados foram analisadas em função da variação da temperatura de substrato. A análise por difração de raios X mostrou que os picos mais intensos são de orientação (204/220) e que os filmes possuem as fases de CuSe, CuSe 2 e CuInSe 2 . Para o processo de condução elétrica foi observada uma única energia de ativação com valor médio de 0,73 eV. A resistência de folha variou entre 0,277 a 0,576 MΩ/□. Os valores de resistividade elétrica apresentaram pequenas variações tendo um valor médio de 1,44 KΩm. As análises da morfologia dos filmes realizadas por microscopia confocal revelaram que de um modo geral as amostras apresentam-se sem trincas, sendo que as superfícies dos filmes com maior temperatura de deposição foram mais uniformes. A caracterização ótica foi realizada no intervalo de comprimento de onda de 350 a 1100 nm e os filmes apresentaram coeficiente de absorção na ordem de 10 3 cm -1 no comprimento de onda de 550 nm e gap ótico com valor médio de 1,5 eV.

ABSTRACTThe Cu 0.6 In 0.4 Se 2 films were deposited on a glass substrate by the spray-pyrolysis technique, for use as a photovoltaic cell absorber layer. The following deposition parameters were adopted: substrate temperature between 250 and 400ºC, precursor solution flow of 1 mL/min and deposition time of 30 min. The structural, electrical, morphological and optical properties of the prepared films were analyzed as a function of substrate temperature variation. X-ray diffraction analysis showed that the most intense peaks are oriented (204/220) and that the films have CuSe, CuSe 2 and CuInSe 2 phases. . For the electric conduction process, a single activation energy with an average value of 0.73 eV was observed. Sheet resistance ranged from 0.277 to 0.576 MΩ/□. The values of electrical resistivity presented small variations having an average value of 1.44 KΩm. The analysis of the morphology of the films made by confocal microscopy revealed that in general the samples presented no cracks, and the surfaces of films with higher deposition temperature were more uniform. The optical characterization was performed in the wavelength range of 350 to 1100 nm and the films had an absorption coefficient in the order of 10 3 cm -1 at the wavelength of 550 nm and optical gap with an average value of 1.5 eV.
