Abstract:In the context of sustainability and in the face of ambitious goals towards the reduction of CO2 emission, the modification of transparency in architecture becomes an important tool of energy flow management into the building. Windows that dim to stop the energy transfer reduce the cooling load in the building. Recently, however, the latest achievements in the development of electrochromic materials allowed us to integrate some additional—previously unknown—functionalities into EC devices. The purpose of this … Show more
“…Some technologies alter the light transmission properties of the windows and are grounded in the use of liquid crystals, polymers, etc. [ 110 ] ( Figure 15 ). We believe that the utilization of magnetic FFs for the fabrication of “smart” windows is a promising technology due to the unique properties of FFs.…”

Magnetite nanoparticles with different surface coverages are of great interest for many applications due to their intrinsic magnetic properties, nanometer size, and definite surface morphology. Magnetite nanoparticles are widely used for different medical-biological applications while their usage in optics is not as widespread. In recent years, nanomagnetite suspensions, so-called magnetic ferrofluids, are applied in optics due to their magneto-optical properties. This review gives an overview of nanomagnetite synthesis and its properties. In addition, the preparation and application of magnetic nanofluids in optics, nanophotonics, and magnetic imaging are described.

“…The EC glazing requires a voltage of up to 10 V in order to enter the active phase. Solutions are being tested in which the EC glazing, similar to batteries, has the ability to store electricity, i.e., the so-called electrochromic energy storage devices (EECD) [22]. Nevertheless, the advantage of all PV-EC configurations results from the convergence of electricity generation and operation of the EC panes.…”

“…Solutions for changing the available colors are also being tested, such as red-blue (CoOx) or yellow-green (Rh 2 O 3 ) [28]. In the case of the EECD glazing in window applications, in addition to the standard color of the active phase, i.e., Prussian blue, a green color is available [22]. The above aesthetic differentiation can be related to the SBS configuration of the PV-EC glazing.…”
The paper provides an architectural analysis of the switchable PV-EC glazing technology based on combining photovoltaic (PV) technology with electrochromic (EC) glazing. The integration of these technologies is considered to constitute future-oriented façade solutions in shaping buildings that are energy-saving and environmentally friendly. The paper aims to define theoretical models of windows using PV-EC technology as solutions adequate from the architectural point of view. To achieve this goal, a comparative analysis of three PV-EC technologies was conducted, i.e., side-by-side (SBS) technology and tandem technologies, namely tandem solid technology (TST) and tandem liquid technology (TLT). The analysis covered functional aspects related to such issues as thermal and visual comfort, energy and aesthetics. The analysis led to extracting the features of the three compared technologies; consequently, their strengths and weaknesses were determined. As a result, seven window models were developed which, based on the above analysis and the insights derived from it, were recognized as the solutions in which the potential of PV and EC technology is best used. The dominant advantages of SBS, being the most developed technology and one with the greatest flexibility in construction applications, are indicated. The research is of a contributory nature, as it constitutes the basis for further numerical and simulation research. Such studies may prove useful to architects in making design decisions, especially at the initial design stages. However, at the current stage of technological development, the study mainly serves as an introduction to further research on improving the PV-EC properties towards integration with the building and its architecture.
