The current unsustainable energy consumption of society has increased the demand for clean and virtually unlimited energy sources, such as solar energy. In the market of solar electricity, building integrated photovoltaics (BIPV) has been receiving considerable attention. For this application, the compatibility of photovoltaic modules with construction materials requires the development of flexible, low-weight, thin-film solar cells. MAPbI3 solar cells (1.55 eV bandgap) with light trapping (LT) structures were chosen for this study, as these have excelled at maintaining high optical performance, despite low cell thickness.A particularity of the BIPV industry is that, unlike most photovoltaic studies, the aesthetics related to the colours of the building material are valued. Thus, this work developed a computational method that designs solar cells with LT features capable of increasing both the optical performance and the solar cell affinity to a specific colour. The focus was then to study how the geometrical features of solar cells and respective LTs affect the colour and optical properties, as well as their layout optimization and angular sensitivity. Here we specifically addressed magenta and green chromaticity since these cover the reflection peaks of the primary colours in the RGB system, and are generally some of the hardest colorations to obtain for high-performance solar cells.A variety of LTs were designed, simulated and optimized, from simple gratings to complex semi-spheroids. The maximum current density values were obtained for solar cells with top dome structures-22.07mA/cm2 for magenta and 21.40mA/cm2 for green - reaching an increase of 6.68% and 3.44%, respectively, relative to the reference cell in planar configuration. Regarding angular homogeneity, this work tested incidence angles between 0◦ and 60◦, where, at the highest illumination angle, a maximum current density of JSC = 20.85mA/cm2was obtained, for magenta domes, corresponding to a relative JSC loss of 5.53%.

520 $a O atual consumo de energia insustentavel aumentou a procura de fontes de energia limpa ilimitadas, como a energia solar. No mercado de eletricidade solar, fotovoltaicos integrados em edificios (BIPV) tem recebido consideravel atencao. A compatibilidade dos modulos fotovoltaicos com os materiais de construcao requer o desenvolvimento de celulas solares de filme fino, flexiveis e de baixo peso. Celulas de MAPbI3, (bandgap1.55 eV) com estruturas de captura de luz (LT) foram escolhidas para este estudo, devido as suas excelentes propriedades oticas, apesar da baixa espessura da celula.Uma particularidade desta industria e o valor estetico da cor dos materiais de construcao, algo raramente considerado em estudos fotovoltaicos. Nesse sentido, este trabalho desenvolveu um metodo computacional que concebe celulas solares com estruturas LT, responsaveis por aumentar a performance otica e pela reflexao de uma cor especifica na celula solar. Este estudo focou-se no modo como as caracteristicas geometricas das celulas solares e LTs afetam a cor e as propriedades opticas, bem como na otimizacao dos layouts e sensibilidade angular. Aqui abordamos especificamente as cromaticidades magenta e verde, uma vez que estas cobrem a reflexao das cores primarias no sistema RGB e sao, geralmente, das coloracoes mais dificeis de obter para celulas solares de alto desempenho.5Uma variedade de LTs foram projetados, simulados e otimizados, desde gratings simples ate semiesferoides complexos. Os valores maximos de densidade de corrente foramobtidosem celulas solares com estruturasem cupula-22.07mA/cm2 para magenta e 21.40mA/cm2 para verde-atingindo um aumento de 6,68% e 3,44%, respectivamente, em relacao a celula plana de referencia. Relativamente a homogeneidade angular, este trabalho testou angulos de incidencia entre 0◦ e 60◦, onde,no maior angulo,uma densidade maxima de corrente de 20.85mA/cm2foi obtida para cupulas magenta, correspondendo a uma perda relativa JSC de 5,53%.
