“…Different nanoscale structures like mesoporous inorganic films mixed with organics, alternating inorganic-organic lamellar structures and nanowire structures may be made. Hybride solar cells exist in many variations and combinations and thus constitute a very broad group of solar cells, where e.g., nanoparticle, nanowire, quantum dot, graphene, carbon nanotube, conjugated polymer, silicon, cadmium telluride, cadmium sulfide, perovskite, titanium dioxide and dye sensitized materials among others are being applied [86][87][88][89][90][91][92][93][94][95][96][97][98][99][100].…”

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.

BACKGROUND: Cyclic aromatic disulfides (CAD) can be used as cross-linking agents or precursors for the synthesis of high temperature resistant polymers such as poly(phenylene disulfides) (PPD). Chemical synthesis of CAD relies on the use of corrosive agents, detrimental for the environment. This paper reports an environment friendly chemoenzymatic procedure to obtain PPD starting from simple aromatic dithiols. RESULTS:The enzymatic reaction was carried out in an aqueous mixture with acetonitrile as co-solvent, using 1,4-and 1,3-benzenedithiol as monomers and a fungal laccase (EC 1.10.3.2) as catalyst. The products obtained were identified as mainly cyclic aromatic disulfides. Thermal analysis suggested that the enzymatically-synthesized CAD display thermal stability and are amenable precursors of high molecular weight sulfur-containing polymers through solvent-free, melt ring opening polymerization (mROP). After mROP, polymeric molecules around 12.8 kDa were obtained and identified as PPD. The resultant PPD shows uniform size, resistance to temperatures up to 400 ∘ C and electrical insulating properties. CONCLUSION: Laccase-catalyzed synthesis of CAD represents a novel reaction, not previously described elsewhere for oxidoreductases. A 100% substrate conversion was achieved under mild reaction conditions and no over-oxidation of CAD was observed, representing an advantage over chemical synthesis. The CAD products precipitated completely from the reaction medium, thus simplifying the purification process.

“…The heterojunction provides a three-dimensional blend of electron-donating and electron-accepting materials characterised by a large donor/acceptor interface area which increases the probability of exciton capture and dissociation, thereby increasing the potential power output of the solar cells [5][6][7] . Furthermore, it has been suggested that creating BHJs composing of both conductive organic polymers and inorganic nanocrystals could combine material advantages, such as flexibility and stability, of organic and inorganic devices 8 . However, the synthesis of these devices often requires multiple steps, causing complications for large scale implementation for future commercialisation opportunities 1,5,6,9 .…”

“…However, the synthesis of these devices often requires multiple steps, causing complications for large scale implementation for future commercialisation opportunities 1,5,6,9 . With regard to the fabrication of BHJs for energy harvesting applications, poly(3-hexylthiophene) (P3HT) is commonly used as the organic component, due to its high absorption coefficient (roughly 10 5 cm -1 ) within the visible region of the solar spectrum 3,8 . Whereas for the inorganic component, metal sulphides have been extensively studied 10,11 .…”
