New insights into Viticulture, Enology and Vitivinicultural Economy arise from the fourteen articles published by the Ciência e Técnica Vitivinícola in 2021. Research carried out by several international teams covered a wide range of topics that seek to respond to current main challenges: chemical, morphological and anatomical features of the grapevine cultivars explored to withstand biotic and abiotic stresses; seaweed foliar application to grapevines as an innovative and integrated vineyard management technique; nutritional management of grapevine cultivars under cold climate conditions and under water constraint scenarios; viability and cost-effectiveness of photovoltaic solar energy for wineries; viticultural technologies and the food safety of wine; characterization of grapes and methods for juice production; chemical composition of grape seeds; development of analytical and sensory methodologies; portrait of the wine spirits sector in Portugal and its recent evolution.

Perovskite Photovoltaic

Methyl ammonium lead iodide CH3NH3PbI3 Perovskite was synthesized by a new method mixing between one and two steps, in addition, the ethanol solvent was used to dissolve CH3NH3I and compared with isopropanol solvent. The characterizations of synthesized perovskite samples included the structural properties, morphological characteristics and optical properties. The intensity and orientation in X-ray diffraction patterns appear clearly in ethanol solvent while disappearing at a peak at 12o due to the speed reaction of perovskite in this solvent. Additionally, the ethanol solvent increasing the grain size of perovskite which homogeneity of the surface morphology. the ethanol solvent cause a decrease in the wavelength of absorbance edge in addition to an increase in the energy bandgap value. Keywords: Ethanol Solvent, Perovskite, Photovoltaic Technologies, X-ray diffraction.
