“…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.

“…IS has been extensively applied to many photovoltaic systems, such as dye-sensitized solar cells [33], organic solar cells [34] and perovskite solar cells [35][36][37][38][39]. IS corresponds to a frequency-dependent technique that allows decoupling electronic parameters, such as capacitances and resistances in photovoltaic devices.…”

“…Using an optimum thickness of 6 nm, these PT-based cells achieved a mean efficiency of 14.7% [25], compared to the relative low (11%) efficiency of the reference PEDOT:PSS cell. Such results show that PT can indeed work as efficient hole transporters.…”

“…This polymer has been used as a 9 nm-thick HTL of a perovskite solar cell based on CH 3 NH 3 PbI 3 in an inverted device architecture and with C 60 as the electron transport layer [25]. In this configuration, the PPN HTL allowed an open-circuit voltage of 970 mV, a short-circuit current density of 19.7 mA¨cm´2, a fill factor of 66% and a PCE of 12.8%, while the reference cell with a PEDOT:PSS HTL reached only a PCE of 11% and a low of V OC of 790 mV.…”

“…With the benefit of its insolubility in DMF, a high mean efficiency of 15.8% was achieved in 2015, with a V OC of 1.02 V and a J SC of 21 mA¨cm´2, the champion cell reaching even a PCE of 16.5% [25]. Associated with a very smooth surface, the PPP film had a thickness of 11 nm and shows a ten-times higher recombination resistance (as measured by electrochemical impedance spectroscopy) than that measured on PEDOT:PSS (7ˆ10 6 Ω against 8ˆ10 5 Ω).…”

Hybrid organometal halide perovskites have attracted much attention these past four years as the new active layer for photovoltaic applications. Researches are now intensively focused on the stability issues of these solar cells, the process of fabrication and the design of innovative materials to produce efficient perovskite devices. In this review, we highlight the recent progress demonstrated in 2015 in the design of new π-conjugated organic materials used as hole transporters in such solar cells. Indeed, several of these "synthetic metals" have been proposed to play this role during the last few years, in an attempt to replace the conventional 2,2 1 ,7,7 1 -tetrakis-(N,N-di-4-methoxyphenylamino)-9,9 1 -spirobifluorene (Spiro-OMeTAD) reference. Organic compounds have the benefits of low production costs and the abundance of raw materials, but they are also crucial components in order to address some of the stability issues usually encountered by this type of technology. We especially point out the main design rules to reach high efficiencies.
