Avaliação do efeito de corantes em células fotovoltaicas para uso integrado em edificações

Abstract

This work focuses on the integration of photovoltaic modules into buildings, particularly through the Building-Applied Photovoltaics (BAPV) and Building-Integrated Photovoltaics (BIPV) approaches, which are gaining popularity due to their potential to reduce the dependence on non-renewable energy sources and promote sustainability. The challenge lies in creating photovoltaic products that are aesthetically pleasing while maintaining high performance. The study proposes to evaluate the behavior of solar cells before and after encapsulation using different colors, with the aim of quantifying the effect of each color on solar cell performance. The results show that encapsulation using dyes significantly reduces the levels of short-circuit current along with an increase in opacity. The highest losses occurred with black color with losses near 67%. The findings suggest that there is a trade-off between the level of coloration and desired architectural and civil integration.
