Abstract:Building integrated photovoltaics (BIPV) offer an aesthetical, economical and technical solution to integrate solar cells harvesting solar radiation to produce electricity within the climate envelopes of buildings. Photovoltaic (PV) cells may be mounted above or onto the existing or traditional roofing or wall systems. However, BIPV systems replace the outer building envelope skin, i.e., the climate screen, hence serving simultanously as both a climate screen and a power source generating electricity. Thus, BIPV may provide savings in materials and labor, in addition to reducing the electricity costs. Hence, for the BIPV products, in addition to specific requirements put on the solar cell technology, it is of major importance to have satisfactory or strict requirements of rain tightness and durability, where building physical issues like e.g., heat and moisture transport in the building envelope also have to be considered and accounted for. This work, from both a technological and scientific point of view, summarizes briefly the current state-of-the-art of BIPV, including both BIPV foil, tiles, modules and solar cell glazing products, and addresses possible research pathways for BIPV in the years to come.

“…Fabrication of multifunctional super-hydrophobic fi lms and coatings is gaining more and more academic and industrial interest due to a combination of liquid repellency with other properties such as electrical conductivity [1][2][3][4][5][6][7][8] , magnetic activity [9][10][11][12][13][14] , transparency [15][16][17][18][19] , antimicrobial properties [20][21][22][23][24][25] , strong substrate adhesion [26,27] , mechanical robustness [27][28][29][30][31][32] , icing prevention [33][34][35][36][37][38][39][40][41][42][43] and self-healing [44] . As such, multifunctional liquid repellent fi lms and coatings can be used in many applications including corrosion prevention, electromagnetic shielding, biomedical technologies, lab-on-a-chip, solid state and electrochemical batteries, membrane science, exterior/interior paint and coatings industry to name a...…”

“…Various other investigations also exposed superhydrophobic surfaces to icing conditions and reported similar observations, i.e., ice accretion was delayed but would eventually occur after an extended period of time. [10][11][12][13][14][15][16][17][18] One of the few cases that reported complete ice prevention involved the use of an electrical heater to assist in ice shedding on a superhydrophobic surface. 19 Therefore, it is clear from these studies that the current designs of superhydrophobic surfaces cannot inherently thwart the occurrence of ice formation.…”

Superhydrophobic coatings have shown promise in reducing both ice accretion and accumulation on a surface. However, recent studies revealed conflicting reports of ice adhesion strength on superhydrophobic surfaces. Therefore, a comprehensive experiment was conducted to measure the ice adhesion strength of a variety of hydrophobic and superhydrophobic coatings by subjecting test substrates to a super-cooled spray consisting of 20 µm droplets in a walk-in cold chamber, and at an air temperature of -20°C. The accreted ice was then removed by pressurized air in a tensile direction for a mode-1 fracture. The relationships between surface wettability, roughness parameters and ice adhesion were then studied in detail. Results showed that for hydrophobic surfaces, a high contact angle and receding contact angle resulted in a lower ice adhesion strength. However, ice adhesion strength for superhydrophobic surfaces correlated weakly with receding contact angle. It was discovered that low surface autocorrelation lengths for superhydrophobic surfaces would result in low ice adhesion strength. This is due to the fact that closely spaced surface features create a high capillary pressure between the surface asperities to resist the penetration of impacting super-cooled droplets to result in ice formation at a Cassie wetting state. However, if the surface asperities are infiltrated with water droplets, the ice adhesion strength can be affected by secondary surface roughness parameters such as arithmetic mean roughness, kurtosis and skewness. Nomenclature 2τ= cohesive fracture energy ω = adhesive fracture energy υ = Poisson's ratio for ice A = area c = "defect" diameter h = ice accretion thickness E = Young's modulus of ice z = surface feature amplitude P c = critical ice fracture pressure S a = arithmetic surface roughness S sk = surface skewness S ku = surface kurtosis 2 S al = surface autocorrelation length S q = surface root mean square roughness t x = autocorrelation function in the x-direction t y = autocorrelation function in the y-direction
