Powder pressed cuprous iodide (CuI) as a hole transporting material for perovskite solar cells

This study focuses on employing cuprous iodide (CuI) as a hole-transporting material (HTM) in fabricating highly efficient perovskite solar cells (PSCs). The PSCs were made in air with either CuI or 2,2′,7,7′-Tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene (spiro-OMeTAD) as HTMs. A simple and novel pressing method was employed for incorporating CuI powder layer between perovskite layer and Pt top-contact to fabricate devices with CuI, while spiro-OMeTAD was spin-coated between perovskite layer and thermally evaporated Au top-contact to fabricate devices with spiro-OMeTAD. Under illuminations of 100 mW/cm2 with an air mass (AM) 1.5 filter in air, the average short-circuit current density (JSC) of the CuI devices was over 24 mA/cm2, which is marginally higher than that of spiro-OMeTAD devices. Higher JSC of the CuI devices can be attributed to high hole-mobility of CuI that minimizes the electron-hole recombination. However, the average power conversion efficiency (PCE) of the CuI devices were lower than that of spiro-OMeTAD devices due to slightly lower open-circuit voltage (VOC) and fill factor (FF). This is probably due to surface roughness of CuI powder. However, optimized devices with solvent-free powder pressed CuI as HTM show a promising efficiency of over 8.0 % under illuminations of 1 sun (100 mW/cm2) with an air mass 1.5 filter in air, which is the highest among the reported efficiency values for PSCs fabricated in an open environment with CuI as HTM.

Compositionally tunable photoluminescence emission in Cu 2ZnSn(S1-xSex)4 nanocrystals

Inorganic nanostructures: Alloyed Cu2ZnSn(S1-xSe x)4 wurtzite nanocrystals (10nm in size) with a varying composition (x=0-1) were synthesized using a colloidal hot injection route. A photoluminescence (PL) emission study of these nanocrystals shows a compositionally tunable band-gap ranging between 0.9-1.4eV that directly correlates to the sulfur-to-selenium ratio (see picture).

Mixed-valence CuIICuI15I17 cluster builds up a 3D metal-organic framework with paramagnetic and thermochromic characteristics

Four cubane-like CU4I4 units are assembled around an iodine atom to form the giant, mixed-valent CuIICuI 15I17 cluster. The CuIICuI 15I17 cluster and a bipyrazole linker form a 3D open framework with paramagnetic and thermochromic properties. This paper also touches on the resemblance of this cluster to the self-similar object of a Sierpinski tetrahedron.

Boric Ester and Thiourea as Coupling Partners in a Copper-Mediated Oxidative Dehydrosulfurative Carbon-Oxygen Cross-Coupling Reaction

A copper-mediated oxidative dehydrosulfurative carbon-oxygen cross-coupling reaction with boric ester and six-membered cyclic thiourea for single-step production of densely substituted 2-alkoxypyrimidines incorporated in a privileged scaffold is described. This is the first demonstration of boric ester acting as an alkoxy donor in a metal-catalyzed coupling reaction to produce ether. The reaction method offers a shortcut for producing 2-alkoxypyrimidine derivatives with rapid diversification and expands the utility of boric ester and the scope of Liebeskind-Srogl-type reactions.

The Role of Charge Selective Contacts in Perovskite Solar Cell Stability

Lead halide perovskite solar cells have rapidly achieved high efficiencies comparable to established commercial photovoltaic technologies. The main focus of the field is now shifting toward improving the device lifetime. Many efforts have been made to increase the stability of the perovskite compound and charge-selective contacts. The electron and hole selective contacts are responsible for the transport of photogenerated charges out of the solar cell and are in intimate contact with the perovskite absorber. Besides the intrinsic stability of the selective contacts themselves, the interfaces at perovskite/selective contact and metal/selective contact play an important role in determining the overall operational lifetime of perovskite solar cells. This review discusses the impact of external factors, i.e., heat, UV-light, oxygen, and moisture, and measured conditions, i.e., applied bias on the overall stability of perovskite solar cells (PSCs). The authors summarize and analyze the reported strategies, i.e., material engineering of selective contacts and interface engineering via the introduction of interlayers in the aim of enhancing the device stability of PSCs at elevated temperatures, high humidity, and UV irradiation. Finally, an outlook is provided with an emphasis on inorganic contacts that is believed to be the key to achieving highly stable PSCs.
