“…When the thickness and refractive index of the SiN :H are optimized, the colors of solar cells look light blue. To realize colored solar cells, Tobias et al reported a method by changing the thickness of the silicon nitride ( = 1.9) or zinc sulfide ( = 2.3), which acts as a single antireflection coating (ARC) on random pyramid textures [5]. However, this method results in significant sc losses.…”

We presented a method to use SiO2/SiNx:H double layer antireflection coatings (DARC) on acid textures to fabricate colored multicrystalline silicon (mc-Si) solar cells. Firstly, we modeled the perceived colors and short-circuit current density (Jsc) as a function of SiNx:H thickness for single layer SiNx:H, and as a function of SiO2thickness for the case of SiO2/SiNx:H (DARC) with fixed SiNx:H (refractive indexn=2.1at 633 nm, and thickness = 80 nm). The simulation results show that it is possible to achieve various colors by adjusting the thickness of SiO2to avoid significant optical losses. Therefore, we carried out the experiments by using electron beam (e-beam) evaporation to deposit a layer of SiO2over the standard SiNx:H for156×156 mm2mc-Si solar cells which were fabricated by a conventional process. Semisphere reflectivity over 300 nm to 1100 nm andI-Vmeasurements were performed for grey yellow, purple, deep blue, and green cells. The efficiency of colored SiO2/SiNx:H DARC cells is comparable to that of standard SiNx:H light blue cells, which shows the potential of colored cells in industrial applications.

“…By varying the thickness of ARC layers, the spectral reflectance curve can be easily regulated with different peaks in VIS (see Figure 10d). In the literature, Tobias et al [ 93 ] and Zeng et al [ 94 ] have respectively demonstrated c‐Si solar cells with vivid colors involving blue, red, yellow, and green using different ARC materials. Test results show that these colored solar cells achieved PCEs of over 16%.…”

Building‐integrated photovoltaics (BIPVs) stand as a promising solution to provide renewable electricity for achieving zero‐energy buildings, although still hindered from large‐scale implementations due to the difficulty of traditional photovoltaic modules in meeting the standards and aesthetics of architectural materials. The emergence of new photovoltaic materials and devices could pave the way for the future through offering diversity and tunability in colors and transparency along with comparable performance. Herein the recent advances in BIPVs are discussed, starting from an overview of various photovoltaic technologies regarding their material characteristics, state of the art, and adaptability to the built environment. The transparent and colored photovoltaic technologies are then respectively emphasized, concerning design principles, theoretical analysis, technical routes, and corresponding demonstration studies. The various strategies, including the materials and structures adopted to modify the transparency and color of solar cells, are highlighted. Finally, the challenges and future perspectives are addressed, followed by an outlook on factors that are critical for large‐scale implementation of BIPVs in the future.

“…So, in range [0. [2][3][4][5][6][7][8][9][10][11][12][13][14][15] mm, the incident spectrum is decomposed in several spectral bands. For the boundary conditions, in addition to the front and back surface recombination velocity respectively, we take into account current flow at metal-semiconductor interfaces thanks to the Peltier effect (Q P ) and the heat exchange by convection (Q Conv ).…”

“…To adjust the perceived color of a solar cell observed outside a building, we can control the reflection on its top surface, and so adjust the thickness of the anti-reflective coating (ARC) layers [5]. Such a solution is both easy and flexible since we only need to control the duration of a deposited layer.…”

Temperature and color management of silicon solar cells for building integrated photovoltaic

Abstract. Color management of integrated photovoltaics must meet two criteria of performance: provide maximum conversion efficiency and allow getting the chosen colors with an appropriate brightness, more particularly when using side by side solar cells of different colors. As the cooling conditions are not necessarily optimal, we need to take into account the influence of the heat transfer and temperature. In this article, we focus on the color space and brightness achieved by varying the antireflective properties of flat silicon solar cells. We demonstrate that taking into account the thermal effects allows freely choosing the color and adapting the brightness with a small impact on the conversion efficiency, except for dark blue solar cells. This behavior is especially true when heat exchange by convection is low. Our optical simulations show that the perceived color, for single layer ARC, is not varying with the position of the observer, whatever the chosen color. The use of a double layer ARC adds flexibility to tune the wanted color since the color space is greatly increased in the green and yellow directions. Last, choosing the accurate material allows both bright colors and high conversion efficiency at the same time.
