Three new beta-substituted Zn-II-tetraarylporphyrinate dyes (1-3), bearing octyloxy chains at the o,o-, o,p- or o-positions of the four phenyl groups respectively, were synthesized, characterized and investigated as sensitizers for DSSCs. In particular, the alkoxy group position strongly influences their electronic absorption and electrochemical features. Improvements in power conversion efficiency ranging from 40% to 80% were obtained with respect to a reference dye (4) characterized by the presence of sterically bulky t-butyl groups at the m-positions.

Summary: This paper investigates the linear and nonlinear properties of a non-classic push-pull molecule based on the concept of a 'donor-free' chromophore. The results show that the silane-functionalized derivatives exhibit stronger nonlinear optical activity than the nitro substituted, which is significant for second-order nonlinear optical materials.

Effect of the ZnSnO/AZO Interface on the Charge Extraction in Cd-Free Kesterite Solar Cells

Carla Gobbo, Valerio Di Palma, Vanira Trifiletti, Claudia Malerba, Matteo Valentini, Ilaria Matacena, Santolo Daliento, Simona Binetti, Maurizio Acciarri, Giorgio Tseberlidis

Summary: This paper investigates the use of Cu2ZnSnS4 (CZTS) as an absorber material and CdS as a buffer layer in thin film solar cells. However, CdS has toxicity and poor band alignment with CZTS. As an alternative, ZnSnO (ZTO) is used as a buffer layer due to its abundance and non-toxic nature. Atomic layer deposition (ALD) is employed to deposit ZTO with different compositions and thicknesses. The results show that ALD can produce compact and homogeneous ZTO layers without the need for the i-ZnO layer, leading to a simpler and more eco-friendly solar cell structure with comparable efficiencies to the traditional one.

Summary: Thin film photovoltaic devices based on CdTe and Cu(In,Ga)Se2 can be replaced with more environmentally friendly Cu2ZnSn(S,Se)4-based technology. By using manganese as a potential alternative to zinc, it is possible to further reduce production costs and improve sustainability. This study focuses on the growth and characterization of Cu2MnSnS4 thin films, which have shown promising efficiency and voltage in solar devices, but also high defectivity that needs to be addressed for the development of Mn-based photovoltaics.

Steric hindrance in the on-surface synthesis of diethynyl-linked anthracene polymers

Simona Achilli, Francesco Tumino, Andi Rabia, Alessio Orbelli Biroli, Andrea Li Bassi, Alberto Bossi, Nicola Manini, Giovanni Onida, Guido Fratesi, Carlo Spartaco Casari

Summary: This research demonstrates that the formation of polymers hosting sp carbon chains using anthracene-based precursor molecules on Au(111) is affected by steric hindrance between aromatic groups. Through scanning tunneling microscopy experiments and density functional theory simulations, it is found that the de-metalation of organometallic structures leads to a lateral separation of adjacent polymers, preventing the formation of ordered domains.
