“…Gewohn et al [20,58] used an experimental approach similar to Saw et al [55] and based on measured external quantum efficiency and reflectance of modules coloured with eight colourants (CMYK, RGB, and white) to develop a model for the prediction of final appearance and yield of arbitrarily coloured BIPV modules. The model was based on coloured textile (CoTex) layers that were laminated onto the front glass.…”

“…In the last few years, some research has investigated the manufacturing process of coloured PV modules, and different technologies have been demonstrated. Furthermore, experimental evaluations of the electric behaviour of coloured modules have been conducted, including in real exposure conditions [23][24][25][26][27][28], and reviews have been published about the available technologies and their related performance [6,14,[29][30][31]. On the other hand, the scientific literature is currently lacking an extensive review of the models and simulation frameworks used to assess and investigate the relation between colours and performance in BIPVs.…”

Coloured building integrated photovoltaics (BIPVs) may contribute to meeting the decarbonisation targets of European and other countries. Nevertheless, their market uptake has been hindered by a lack of social acceptance, technical issues, and low economic profitability. Being able to assess in advance the influence of the coloured layers on a module’s power generation may help reduce the need for prototyping, thereby allowing optimisation of the product performance by reducing the time and costs of customised manufacturing. Therefore, this review aims at investigating the available literature on models and techniques used for assessing the influence of coloured layers on power generation in customised BIPV products. Existing models in the literature use two main approaches: (i) detailed optical modelling of the layers in the module’s stack, including coloured layers, and (ii) mathematical elaboration of the final product’s measured characteristics. Combining the two approaches can provide improved future models, which can accurately assess every single layer in the module’s stack starting from measured parameters obtained with simpler equipment and procedures.

“…[ 6,7 ] Other techniques studied include the use of automotive paints, [ 8 ] colored polymers, [ 9 ] as well as the use of textiles. [ 10 ] The technologies mentioned so far produce colors using absorptive materials. Other approaches focus on light management, like the implementation of resonant nano‐scatterers [ 11 ] or the Morpho‐color concept, which uses nanostructures that, via interference effects, can produce significant reflectance of light (>60%) on wavelengths that belong to blue, green, and red hues.…”

Herein, the application of a comprehensive modeling framework that can help optimize the design of multilayered optical filters for coloring photovoltaic (PV) modules is presented based on crystalline silicon solar cells. To overcome technical issues related to the implementation of color filters (CFs) on PV modules, like glare and color instability, colorimetry metrics, such as the hue, chroma, luminance color space, and the quantitative concept of difference between two colors are extensively deployed. It is showcased in this work that designing colored modules with high hue and chroma stability is possible by using a front‐side texturing with edged geometry, like V‐shaped grooves and inverted pyramids, while obtaining colors with relatively high luminance values, indicating good brightness. Furthermore, it is argued that adapting the rear surface of the front glass with a random textured layout where the CF is applied can improve color and luminance stability without significant loss of chroma while eliminating glare. Finally, the models can be used to optimize the number of layers for a given CF, reducing unnecessary optical losses. Compared to a standard PV module, performance simulation of optimized, bright‐colored PV modules predicts relative energy yield losses ranging from 7% to 25%.

“…The underlying idea is that additional surfaces may thus be unlocked for PV electricity generation. Options in various stages of development include colouring of glass, 7 foils 8,9 or textiles 10 in front of the cells, up to assembling even semi‐transparent stone or wood veneer in front 11 . A more detailed review has been published by PVPS task 15 12 .…”

In this paper, we first give some historical background and trends in PV module technologies with a focus on the growing trend towards ‘PV everywhere’, mainly targeting improved aesthetics, dimensional freedom including curved surfaces, weight concerns and specific reliability testing. This section acts as an introductory review of the field.Then, in the following sections, we elaborate on two technological developments in this field where we are active: (i) multi‐wire interconnection and (ii) advanced encapsulation.In terms of multi‐wire interconnection, this technology offers improved aesthetics, a similar performance and dimensional freedom compared to the traditional tabbing‐stringing process, and the experiments show promising results on extended reliability testing, including thermal cycling, damp heat and humidity freeze, as well as high‐temperature storage.In terms of advanced encapsulation, we introduce our approach for curved surfaces using a double‐membrane laminator and present results on fabricating curved modules, targeting as demonstration examples on the one hand, glass–glass sunroofs, and on the other hand, lighter‐weight bonnets for automotive applications.We mix examples targeting building and automotive applications, to illustrate the variety of requirements (colours, curvature, weight, reliability, safety), although this variety within building and vehicle applications is probably as large as between them.
