Summary: A facile and robust deposition technique, doctor-blading, is used to efficiently fabricate high-quality perovskite solar cells (PSCs) under a wide range of humidity. By combining an ionic liquid and molecular additives, the morphology and crystallization process of the perovskite film are modulated, resulting in large-size crystal, low defect density, and ultrasmooth surface. The achieved power conversion efficiency (PCE) of 20.34% for doctor-bladed PSCs is the highest reported for one-step solution-processed PSCs without antisolvent assistance.

Summary: The study investigates the impact of Se incorporation on the structural and optical properties of Cu2ZnSnS4 thin films using a simple and cost-effective dip coating technique. The results show that the lattice parameters, morphology, and band gap of CZTSSe films vary with respect to the S/(S + Se) ratio, as characterized through various analysis techniques. Achieving a CZTSSe film with a band gap of 1.27 eV and S/(S + Se) around 30% requires annealing the precursor film with 15 mg of elemental selenium powder.

Summary: This paper presents a geometric method of lattice reduction based on cycles of directional and hyperplanar shears. The 'basis rhombicity' parameter is used to evaluate the deviation from cubicity at each step of the reduction, which is the sum of the absolute values of the elements of the metric tensor associated with the basis. The levels of reduction achieved by this method are similar to the Lenstra-Lenstra-Lovasz (LLL) algorithm, especially for dimensions below 20. This method can be applied to reduce unit cells attached to given hyperplanes.

Summary: The phenomenological theory of martensite crystallography (PTMC) has limitations in describing the structures of variants and the roles of symmetries and metrics. A new theory called correspondence theory (CT) is proposed, which explains martensite variants based on correspondences and symmetries. The study shows that specific misorientations and inter-correspondences between variants have a one-to-one relationship. The prediction of twins' junction planes can be made without calculating stretch matrices.

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

Summary: The phenomenon of ribbon lengthening in PV modules exposed to thermal cycling is not well explained in the literature. In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.

Summary: This study found that decorating subwavelength arrays with SiO2 quasi-nanolenses (qNL arrays) can enhance the absorption of the solar spectrum. Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
