Enhanced performance of carbon-based planar CsPbBr3 perovskite solar cells with room-temperature sputtered Nb2O5 electron transport layer

Inorganic CsPbBr3 perovskite solar cell (PSC) has attracted much attention owing to its outstanding air and thermal stability and low cost manufacture process. Crystalline TiO2 (c-TiO2) has been widely used as electron-transporting layer (ETL) material for inorganic CsPbBr3 PSC. However, c-TiO2 requires high-temperature (>450 C) fabrication process which impedes the application of flexible inorganic CsPbBr3 PSC and its low electron mobility further limits the performance enhancement. Herein, we prepared novel amorphous Nb2O5 (a-Nb2O5) ETL through a facile room-temperature sputtering method for inorganic planar CsPbBr3 PSC. The PSC with a-Nb2O5 ETL has gained a champion efficiency of 5.74%, which is higher than that of the PSC (5.12% or 4.67%) based on crystalline Nb2O5 (c-Nb2O5) ETL or c-TiO2 ETL by high-temperature (500 C) annealing. The improved photovoltaic characteristic for CsPbBr3 PSC with a-Nb2O5 ETL may be ascribed to its suitable work function, high optical transmittance, low charge recombination at the a-Nb2O5/CsPbBr3 interface and the superior crystallinity of CsPbBr3 film deposited on a-Nb2O5 ETL. Moreover, the a-Nb2O5-based CsPbBr3 PSC without encapsulation exhibits a good long-term stability in ambient atmosphere. This work offers a new research direction for preparing high-performance inorganic PSC.

Review of current progress in inorganic hole-transport materials for perovskite solar cells

Plenty of options for inorganic electron transport materials (ETMs) for perovskite solar cells (PSCs) are available. However, most hole transport materials (HTMs) is of organic nature. Organic materials are less stable as they are easily degraded by water and oxygen. Developing more variants of inorganic HTM is a major challenge. Till date, many materials have been reported, but their performance has not superseded that of their organic counterparts. In this review article, we look into the various inorganic HTMs that are available and analyze their performance. Apart from stability, their performance is also a concern for reproducible parameters of device performance. CuSCN, NiOx and MoS2 based PSCs are highly stable devices, maintaining power conversion efficiency (PCEs) over 20% whereas, number of devices made from CuI, CuOx, CuS, CuGaO2 and MoOx but shows low PCEs below 20%. Recently, HTM-free carbon/CNTs/rGO based PSCs shows promises for commercialization. Inorganic HTMs is overcoming the stability and cost issue over organic HTMs, various techniques, their novelty is shown in this work which will contribute in paving a path for synthesizing the ideal inorganic HTM for PSCs.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Structural versatility and electronic structures of copper(i) thiocyanate (CuSCN)-ligand complexes

Copper(i) thiocyanate (CuSCN) is a promising semiconductor with an expansive range of applications already demonstrated. Belonging to the group of coordination polymers, its structure can be easily modified, for example via ligand (L) coordination. In this work, we have analyzed in detail the crystal structures of 26 CuSCN-L complexes that exhibit diverse structures changing from the 3D networks of the parent CuSCN to 2D sheet, 1D ladder, 1D zigzag chain, 1D helical chain, and a 0D monomer as well as intermediate bridged structures. We outline herein the basic structural design principles based on four factors: (1) Cu(i) geometry, (2) CuSCN?:?L ratio, (3) steric effects, and (4) supramolecular interactions. In addition, we employ density functional theory to study the electronic structures of these 26 complexes and find that the opto/electronic properties vary over a wide range, e.g., widened or reduced fundamental band gaps, restricted hole transport due to Cu-SCN network disruption, and the possibility of electron transport through the ligand states. We also observe a correlation between the electronic properties and the dimensionality of the Cu-SCN network. Lowering the dimensionality of the 3D structure to 2D, 1D, and 0D by increasing the number of coordinating ligands, the dispersion and the width of the top valence bands decrease whereas the energy difference between the Cu and SCN states expands. Aliphatic ligands in most cases do not generate electronic states in the band gaps whereas aromatic ligands give rise to states between the Cu and SCN states that lead to optical absorption and emission in the visible range. This study provides guidelines for developing coordination polymer semiconductors based on the Cu-SCN network. The 2D structure is identified as a promising platform for designing new CuSCN-based materials as it retains the carrier transport properties while allowing for properties tailoring through ligand coordination.

The first two inorganic-organic hybrid three-dimensional (3D) polyoxotantalates (POTas) and the first two inorganic-organic hybrid 2D POTas have been obtained. All of these high-dimensional POTas are built from a new-type POTa dimeric cluster {Cu(en)(Ta6O19)}2/{Cu(enMe)(Ta6O19)}2 (en = ethylenediamine, enMe = 1,2-diaminopropane) bridged by copper complexes. Interestingly, extended POTas 1 and 3 can undergo single-crystal to single-crystal structural transformations triggered by water.
