“…After working under 1 sun in air for more than 1000 h, the cells still gave stable PCE (Figure 4 e) [ 63 ] and CH 3 NH 3 PbI 3 led to a better interface and improved device performance. [ 66 ] Effects of TiO 2 nanoparticle size and carbon electrode composition on the device performance were systematically studied. [ 67 ] This printing technique has potential for mass production of perovskite solar cells.…”

widely commercialized, but possiblities to increase their performance are limited, because nowadays the so-called balance of systems (BoS) cost of PV modules makes up most of the cost. [ 1 ] As much of the BoS scales with area, performance improvement seems the only way to decrease the cost of PV power further. Therefore, new PV cells are sought either to allow for higher effi ciencies than what is possible with Si PV without cost increase, or, as explained in section 3.4, to provide lowcost added effi ciency to Si PV. Emerging solar cells such as dye-sensitized, bulkheterojunction and quantum-dot solar cells can be fabricated via low-temperature solution processing, that holds promise for low-cost large scale application, but best power conversion effi ciencies (PCE) are half of, or less than that of the best commercial Si PV cells. [ 2 ] This is where perovskite solar cells enter, as for the fi rst time in PV history it is possible to produce high-effi ciency cells at low monetary and energy costs, with apparent ease of fabrication from earth-abundant, readily available raw materials. The PCE for perovskite solar cells has increased from 2.2% to 20.1% since 2006, showing an inviting vista of commercialization. [ 3,4 ] Perovskite solar cells are named after the crystal structure of the light absorbers, the structure of the mineral CaTiO 3 . Many compounds with ABX 3 stoichiometry take this structure, where A and B are 12-and 8-coordinates cations, respectively, and X is the anion. [ 4 ] Of the many ABX 3 only few are suitable to be efficient light absorbers for solar cells due to requirements such as appropriate bandgap for good light-harvesting ability, energy level/band alignment with contacting materials, long charge carrier lifetime, τ, and high mobility, µ. Perovskites generally have divalent anions, and the strong electrostatic bonding mostly makes their (high) bandgaps not suitable for solar PV. Mitzi et al. initiated using perovskites containing halides, ammonium cations and Sn 2+ in optoelectronic devices, which formed the basis for the development of perovskites for solar cells. [ 5 ] Here we will focus on such halide perovskites, together with one divalent (Pb 2+ ) and one monovalent (mostly CH 3 NH 3 + ) cation. The most effi cient halide perovskite solar absorbers consist of organic ammonium ions (CH 3 NH 3 + or NH = CHNH 3 + ), Pb 2+ and halide ions (I − , Br − ).[ 4 ] CH 3 NH 3 PbI 3 possesses broad and intense light absorption. It is an ambipolar semiconductor (can be n-or p-type), and its charge carriers can have long diffusion lengths and lifetimes, which allow excellent PCE for solar cells made with it. [3][4][5][6] Another advantage of perovskite absorbers is the low-temperature solution-processing ability, which helps

Stitching triple cation perovskite by a mixed anti-solvent process for high performance perovskite solar cells

With the rapid development of organic-inorganic lead halide perovskite photovoltaics, increasingly more attentions are paid to explore the growth mechanism and precisely control the quality of perovskite films. In this study, we propose a "stitching effect" to fabricate high quality perovskite films by using chlorobenzene (CB) as an anti-solvent and isopropyl alcohol (IPA) as an additive into this anti-solvent. Because of the existence of IPA, CB can be efficiently released from the gaps of perovskite precursors and the perovskite film formation can be slightly modified in a controlled manner. More homogeneous surface morphology and larger grain size of perovskite films were achieved via this process. The reduced grain boundaries ensure low surface defect density and good carrier transport in the perovskite layer. Meanwhile, we also performed the Fourier transform infrared (FTIR) spectroscopy to investigate the film growth mechanism of unannealed and annealed perovskite films. Solar cells fabricated by using the "stitching effect" exhibited a best efficiency of 19.2%. Our results show that solvent and solvent additives dramatically influenced the formation and crystallization processes for perovskite materials due to their different coordination and extraction capabilities. This method presents a new path towards controlling the growth and morphology of perovskite films.

Perovskite solar cells fabricated from organometal halide light harvesters have captured significant attention due to their tremendously low device costs as well as unprecedented rapid progress on power conversion efficiency (PCE). A certified PCE of 20.1% was achieved in late 2014 following the first study of long‐term stable all‐solid‐state perovskite solar cell with a PCE of 9.7% in 2012, showing their promising potential towards future cost‐effective and high performance solar cells. Here, notable achievements of primary device configuration involving perovskite layer, hole‐transporting materials (HTMs) and electron‐transporting materials (ETMs) are reviewed. Numerous strategies for enhancing photovoltaic parameters of perovskite solar cells, including morphology and crystallization control of perovskite layer, HTMs design and ETMs modifications are discussed in detail. In addition, perovskite solar cells outside of HTMs and ETMs are mentioned as well, providing guidelines for further simplification of device processing and hence cost reduction.
