“…Combined use with AVA or other surface passivating additives could therefore offer avenues into further lifetime enhancement [100]. A recent example of such work showed that adding phenethylammonium Iodide (PEAI) reduced PCE loss in AVA0.03MAPbI3 devices stored in ambient conditions, although it should be noted that the devices in this study were of low PCE to begin with (PCE 5.95%) [101].…”

Perovskite solar cells (PSCs) have already achieved comparable performance to industrially established silicon technologies. However, high performance and stability must be also be achieved at large area and low cost to be truly commercially viable. The fully printable triple-mesoscopic carbon perovskite solar cell (mCPSC) has demonstrated unprecedented stability and can be produced at low capital cost with inexpensive materials. These devices are inherently scalable, and large-area modules have already been fabricated using low-cost screen printing. As a uniquely stable, scalable and low-cost architecture, mCPSC research has advanced significantly in recent years. This review provides a detailed overview of advancements in the materials and processing of each individual stack layer as well as in-depth coverage of work on perovskite formulations, with the view of highlighting potential areas for future research. Long term stability studies will also be discussed, to emphasise the impressive achievements of mCPSCs for both indoor and outdoor applications.

“…As illustrated in Figure 20g, the authors reported that the MWCNTs will act as an electrical highway for charge transport between individual perovskite NPs, facilitating the hole collection efficiency of the perovskite/MWCNT interface. Papadatos et al [274] fabricated a HTM-free PSC using a methylammonium/5-aminovaleric acid/phenethylammonium iodide lead perovskite. The HTM-free PSCs utilized a carbon electrode where all processes were conducted under RH of 40 -60%, achieving an efficiency of 7.11%.…”

Unlike fossil fuels, the sun is an inexhaustible energy source that delivers more energy to the earth in 1 h than the entire planet consumes in one year. Energy can be harvested from the sun using photovoltaics (PV) and stored (e.g., batteries), meaning solar energy can be used as and when required. [3,4] Currently, the commercial PV market is dominated by single-junction crystalline silicon (c-Si) PV which deliver power conversion efficiencies (PCE) of over 26% under 1 Sun illumination (AM 1.5 standard). [5,6] Despite their high efficiencies, the fabrication of c-Si PV is nontrivial and lacks electronic tunability. Furthermore, the record efficiency for c-Si PV is 26.7% [5] which is very close to the theoretical limit of 29.4%. [7] This clearly indicates that c-Si PV is a mature technology and there is limited room for improvement. [8] Over the past two decades, third-generation solar cells such as dye-sensitized solar cells, [9,10] quantum dot solar cells, [11,12] organic solar cells, [13,14] and perovskite solar cells (PSCs) [15,16] have been developed as alternatives to c-Si technologies. Of these third-generation solar cells, single-junction PSCs have generated significant attention due to their intense visible to near-infrared absorptivity, [16-18] long diffusion lengths of the charge carriers, [19,20] high efficiency, [21,22] electronic and physical tunability, [23,24] and low manufacturing costs. [25,26] After the first report by Miyasaka's group in 2009, [27] the PCE for single junction devices increased considerably from 3.8% to 25.2%, [27,28] making it the fastest advancing PV technology to date. This has uniquely placed PSCs as the frontrunner technology to potentially replace or coexist with c-Si PV. The term "perovskite" refers to a group of compounds that share the same lattice structure as calcium titanium oxide (CaTiO 3). All PV perovskite materials have the general chemical formula ABX 3 , as illustrated in Figure 1a. Organic-Inorganic hybrid PSCs are typically made using an organic/ inorganic cation (A = methylammonium (MA) CH 3 NH 3 + , formamidinium (FA) CH 3 (NH 2) 2 + , or cesium), a divalent cation (B = Pb 2+ or Sn 2+) , [29] and an anion (X = Cl − , Br − , or I −), illustrated in Figure 1b. [16,30] A is surrounded by eight lead halide octahedra (B in the center of octahedra) and forms a cubic perovskite structure. When the size of A or/and X is changed, the structure of perovskite will distort. The Goldschmidt tolerance factor (t) [31] of perovskite is an empirical index for Organic-inorganic hybrid perovskite solar cells (PSCs) have attracted significant attention in recent years due to their high-power conversion efficiency, simple fabrication, and low material cost. However, due to their high sensitivity to moisture and oxygen, high efficiency PSCs are mainly constructed in an inert environment. This has led to significant concerns associated with the long-term stability and manufacturing costs, which are some of the major limitations for the commercialization of this cutting-edge tech...

“…During the past decade, organic–inorganic halide perovskites (PVKs) have risen as one of the most promising semiconductor families for various advanced applications in optoelectronics, such as light emitting diodes (LEDs) [ 1 ], lasers [ 1 ], photodetectors [ 2 ], scintillators [ 3 ], and solar cells [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ]. PVKs are especially promising for photovoltaic applications due to a broad range of favorable properties: (i) preparation from solutions, at low temperature and low cost, (ii) long charges diffusion lengths, (iii) direct optical transition, (iv) a bandgap that can be tuned by playing on the material composition, and (v) low exciton binding energy [ 2 , …”

“…To date, 2,2′,7,7′-tetrakis( N , N ’-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD) is the most popular hole-transporting material (HTM), and TiO 2 is a popular electron-transporting material (ETM). However, a different cell architecture has proven more suitable for producing highly stable devices [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. It is composed of three stacked mesoporous layers, i.e., TiO 2 /ZrO 2 /carbon.…”

During the past decade, the power conversion efficiency (PCE) of perovskite solar cells (PSCs) has risen rapidly, and it now approaches the record for single crystal silicon solar cells. However, these devices still suffer from a problem of stability. To improve PSC stability, two approaches have been notably developed: the use of additives and/or post-treatments that can strengthen perovskite structures and the use of a nontypical architecture where three mesoporous layers, including a porous carbon backcontact without hole transporting layer, are employed. This paper focuses on 5-ammonium valeric acid iodide (5-AVAI or AVA) as an additive in methylammonium lead iodide (MAPI). By combining scanning electron microscopy (SEM), X-ray diffraction (XRD), time-resolved photoluminescence (TRPL), current–voltage measurements, ideality factor determination, and in-depth electrical impedance spectroscopy (EIS) investigations on various layers stacks structures, we discriminated the effects of a mesoscopic scaffold and an AVA additive. The AVA additive was found to decrease the bulk defects in perovskite (PVK) and boost the PVK resistance to moisture. The triple mesoporous structure was detrimental for the defects, but it improved the stability against humidity. On standard architecture, the PCE is 16.9% with the AVA additive instead of 18.1% for the control. A high stability of TiO2/ZrO2/carbon/perovskite cells was found due to both AVA and the protection by the all-inorganic scaffold. These cells achieved a PCE of 14.4% in the present work.
