“…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.

Continuing growth in global energy consumption and the growing concerns regarding climate change and environmental pollution are the strongest drivers of renewable energy deployment. Solar energy is the most abundant and cleanest renewable energy source available. Nowadays, photovoltaic technologies can be regarded as viable pathways to provide sustainable energy generation, the achievement attained in designing nanomaterials with tunable properties and the progress made in the production processes having a major impact in their development. Solar cells involving hybrid nanocomposite layers have, lately, received extensive research attention due to the possibility to combine the advantages derived from the properties of both components: flexibility and processability from the organic part and stability and optoelectronics features from the inorganic part. Thus, this review provides a synopsis on hybrid solar cells developed in the last decade which involve composite layers deposited by spin-coating, the most used deposition method, and matrix-assisted pulsed laser evaporation, a relatively new deposition technique. The overview is focused on the hybrid nanocomposite films that can use conducting polymers and metal phthalocyanines as p-type materials, fullerene derivatives and non-fullerene compounds as n-type materials, and semiconductor nanostructures based on metal oxide, chalcogenides, and silicon. A survey regarding the influence of various factors on the hybrid solar cell efficiency is given in order to identify new strategies for enhancing the device performance in the upcoming years.

“…Unfortunately, these types of cells present many limitations such as the low charge carrier mobility [8] and low device lifetimes. In order to overcome the low mobility associated to organic materials, many authors have focused on hybrid nanocomposite structure with the aim to combine the properties of organic and inorganic materials in one device such as P3HT poly (3-hexylthiophene) blended with silicon nanowires SiNWs [9,10] which present a high crystallinity degree. Since the discovery of intense photoluminescence from the porous silicon by L.T.…”

Silicon nanowires (SiNWs), with different ratios, have been elaborated by metal assisted chemical etching (MACE) on P3HT:SiNWs blends, deposited onto PET substrate. X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM) and hotoluminescence (PL) measurements have been used to control the structural, morphological and optical properties of the investigated structure. The best concentration chosen is followed by an annealing treatment. Our results prove that the optimal structure is obtained with the nanocomposite P3HT:SiNWs (1:1). The moderate annealing temperature, around 90 °C, is most appropriate. A correlation between XRD, AFM and PL measurements can explain the decrease of charge transfer and the coupled of SiNWs with increasing concentration. Our results can improve the possibility to integrate those kinds of structures as an active layer in the photovoltaic applications.
