High-efficiency perovskite solar cell using cobalt doped nickel oxide hole transport layer fabricated by NIR process

Lead halide perovskite solar cells (PVSCs) have potential toward commercialization because of their high efficiency and low cost. The hole transport layer (HTL) of p-i-n perovskite solar cell is usually made of NiOX. However, the NiOX needs to be processed at 300 C for 15 min for good hole transport property. This long heating time prohibits the development of continuous commercial process. Thus, a rapid heating process for the NiOX film deposition is critical to realize the commercialization of PVSCs in the future. In this study, we develop a facile method to obtain high quality NiOX films annealed by NIR in a short time of 50 s. A short-wave NIR lamp at 2500 K was used to systematically investigate the effect of NIR intensity on the film quality of sol-gel NiOX. The PVSCs fabricated from NIR-annealed NiOX (NIR-NiOX) film show a comparable power conversion efficiency (PCE) to those fabricated from traditional hot-plate annealed-NiOX (HP-NiOX). In addition, the NIR annealed cobalt-doped NiOX (NIR-Co:NiOX) was synthesized to replace pristine NIR-NiOX. The PCE of PVSCs fabricated from this new NiOX film can be increased from 15.99% to 17.77%, which is due to the efficient hole extraction, less charge accumulation, and reducing Voc loss resulting from the improved hole mobility, reduced interface resistance and well-matched work function. Our study paves a way to fulfill the requirements of low cost and low energy consumption of large scale production of high efficiency PVSCs.

Enantioselective alpha-C-H functionalization of amides with indoles triggered by radical trifluoromethylation of alkenes: Highly selective formation of C?CF3 and C?C bonds

A dual copper/chiral phosphoric acid-catalyzed asymmetric tandem remote C(sp3)-H/unactivated alkene functionalization reaction triggered by radical trifluoromethylation of unactivated alkenes for the concomitant construction of C?CF3 and C?C bonds was described. This approach provided an efficient method for the synthesis of valuable chiral trifluoromethylated indole derivatives with excellent regio-, chemo-, and good enantioselectivity.

Transport and chemistry at electroactive interfaces studied using line-imaging Raman spectroscopy

Line-imaging Raman spectroscopy provides a contiguous series of Raman spectra along a line in space. The resulting image provides a one-dimensional spatial profile containing information about the bonding and chemical environment being sampled. The instrument configuration described here has a spatial resolution of about 5 mum and a spectral resolution of approximately 10 cm-1. Two examples highlight the use of in situ line-imaging Raman spectroscopy in electrochemical engineering. In the first example, the cation transport and redox characteristics of a thin (? 36 nm) nickel hexacyanoferrate film are probed. The oxidation state of iron centers within the nickel hexacyanoferrate thin film is shown to be readily modulated between ferric and ferrous states in the freshly prepared film. However, repeated cycling results in an irreversible loss of capacity as the iron centers no longer are able to efficiently switch into the ferric state. In the second example, we demonstrate the simultaneous imaging of a thin film of semiconducting copper (I) thiocyanate and the electrolyte chemistry from which the film was deposited. We show that copper thiocyanate electrodeposits have the beta crystal form and the deposition involves a CuSCN+ precursor that forms via homogeneous solution phase chemistry upon addition of copper sulfate to a potassium thiocyanate containing electrolyte.

Electrodeposition of p-type CuSCN thin films by a new aqueous electrolyte with triethanolamine chelation

A stable aqueous electrolyte solution containing Cu2+ and SCN- was prepared by adding triethanolamine (TEA, N(CH 2CH2OH)3) to chelate with Cu(II) cations. The electrolyte solutions were basic, with pH values in the range of 8.5-9, and could be used in the electrodeposition of CuSCN as a hole-conducting layer on a ZnO substrate and as an electron-conducting layer for nanocrystal photovoltaic cells because it could prevent the ZnO layer from acidic etching. CuSCN films were potentiostatically deposited on indium tin oxide glass substrates through the aqueous solutions, and the deposition potential for the sole CuSCN phase layer was determined by a linear sweep voltammetry measurement. The influence of applied potentials, electrolyte components, and deposition temperatures on the stoichiometry, phase, and particle morphology of the CuSCN films was investigated by X-ray photoelectron spectra, X-ray diffraction, and a field-emission scanning electron microscope. The results showed that the morphology of the dense CuSCN films was trigonal pyramid and the stoichiometric portions of SCN/Cu were excess of SCN. The current-voltage (I-V) characteristic of the junction between electrodeposited CuSCN and ZnO nanostructured layer displayed p-type semiconductor characteristics of CuSCN. The transmittance measurements detected high transmittance (?87%) in the visible wavelength range, and the direct transition band gap calculated was 3.88 eV.

Evaluation of Small Molecules as Front Cell Donor Materials for High-Efficiency Tandem Solar Cells

Three small molecules (SMs) (DR3TSBDT, DR3TBDTT, and DRBDT-TT) were used as the front cell donor materials for highly efficient tandem OSCs which ensured both high open-circuit voltages and current density. The SM:PC71BM single-junction cell was fabricated with a structure of ITO/CuSCN/SM:PC71BM/ETL-1/Al. A thin layer of CuSCN processed from dimethyl sulfi de solution was spin-cast on top of precleaned ITO substrates and annealed in air at 120C for 10 minutes. or DR3TBDTT:PC71BM, chloroform was used for solvent vapor annealing. The tandem OSCs based on DR3TBDTT and DRBDT-TT also showed high PCEs of 10.73% and 10.43%, respectively. However, the overall open-circuit voltages is a little lower than the sum of open-circuit voltages of the subcells, suggesting a suboptimal contact at active layer/intermediate layer interface. A higher PCE would be obtained if the ICLs would be further optimized. All these demonstrate that the monodisperse SMs could perform as promising donor materials for high-performance tandem solar cells.

Inorganic Hole-Transporting Materials for Perovskite Solar Cells

In the last few years, inorganic?organic metal halide perovskite solar cells (PSCs) have attracted a great deal of attention as a promising next-generation solar-cell technology because of their high efficiencies and low production cost. Hole-transporting materials (HTMs) play an essential role in effective charge extraction and thus in achieving high overall efficiency. Therefore, searching for an efficient, stable, and low-cost HTM in PSCs has been one of the hottest research topics in this field. Inorganic p-type semiconductors that possess several appealing characteristics, such as suitable energy levels, high hole mobility, and high chemical stability, as well as low production cost, etc., are promising HTM candidate materials in PSCs. Here, specific attention is paid to the recent progress in inorganic HTMs being explored for PSCs. A variety of methods developed for the fabrication of these inorganic HTMs are summarized in detail, together with their corresponding performance in PSCs. Finally, an outlook on further enhancements of highly efficient PSCs based on inorganic HTMs is presented.
