“…These materials mostly contain three main components: a divalent cation, which is frequently lead, a nitrogen-based cation, and halide anions. Since lead is a toxic element, research has been conducted to replace this element with different options [11,12]. In this paper, we use manganese halide compounds to build materials emitting in the near-infrared (NIR) region.…”

In recent years, metal-halide hybrid materials have attracted considerable attention because materials, such as lead-iodide perovskites, can have excellent properties as photovoltaics, light-emitting devices, and photodetectors. These materials can be obtained in different dimensionalities (1D, 2D, and 3D), which directly affects their properties. In this article, we built 0D, 1D, and 2D manganese halide materials with 3-aminopyridine (3AP) or 4-ethylpyridine (4EtP). Two isomorphic complexes with 3AP and manganese chloride ([MnCl2(3AP)4]) or manganese bromide ([MnBr2(3AP)4]) were obtained with the amino group in 3AP assisting in the formation of 0D structures via hydrogen bonding. By modifying the reaction conditions, 3AP can also be used to build a 2D coordination polymer with manganese chloride ([MnCl33AP]− [3APH]+). Unlike 3AP, 4EtP does not provide the opportunity for hydrogen bonding, leading to the formation of two additional isomorphic compounds built of individual 1D chains with manganese chloride ({MnCl3(4EtP)2}n) and manganese bromide ({MnBr2(4EtP)2}n). In the visible region, the 0D and 1D manganese halide compounds have similar photoluminescence properties; however, 0D and 1D have different near-IR emissions. In conclusion, hydrogen-bonding groups can play a role in the formation of discrete manganese-halide units, 1D halide chains, or 2D polymeric sheets.

“…This new design of dual absorbers has been reported in thinfilm CZTS/CIGS, PbS, and perovskite/ perovskite materials. [9][10][11][12][13][14][15][16][17][18] We undertook a theoretical investigation of this design in lowering the nonabsorption and thermalization losses.Our double-absorber device is distinct from tandem or multijunction device in a way that tandem is the current-matched device with a tunnel junction in between. It has complex additional circuitry to be fabricated and managed, resulting in parasitic losses and an intricate fabrication process.…”

The solar cell device architecture is critical for photovoltaic action and achieving high efficiency. Herein, a dual‐absorber solar cell is demonstrated where a stack of two band‐aligned absorbers with different bandgaps facilitates absorption of a broader range of the solar spectrum resulting in higher short‐circuit current. This dual‐absorber design is analyzed and a narrow range of optimal parameters which can achieve net efficiency gain is summarized. By introducing an additional absorber–absorber interface, the interfacial defect and band offset become essential parameters for the efficient functioning of a dual‐absorber device. Single‐, double‐, and triple‐absorber configurations, their performance enhancement, and synergetic spectrum utilization are compared. The proposed dual‐absorber design is more straightforward and has comparable performance to a tandem device, thus presenting a potentially cost‐effective solar cells design.

The current global scenario underlines the urgency of addressing energy consumption and its environmental implications. Contemporary international strategies aim to foster public awareness and engagement in sustainable energy initiatives. The World Environment Protection Commission aspires to qualify for an equitable transition toward energy‐efficient technologies, strategic policies, and achieving net‐zero carbon emissions. The principal aspiration is to enhance community understanding of energy and environmental policies. Furthermore, a root cause analysis reveals that understanding the foundational factors, both internal and external, underpinning the attainment of these objectives is of paramount importance. This study investigates the comparative advantages of renewable energy over non‐renewable sources. It conducts a thorough analysis of various factors, encompassing energy sourcing, variables, challenges, technological progress, and the deployment of energy‐efficient systems. Utilizing a strategic approach and conducting pre‐ and post‐analysis data evaluations, it aims to promote the adoption of sustainable practices for a greener future. Emphasizing the importance of international cooperation and the effective implementation of policies, this research underscores the critical role of practical action in fostering energy sustainability and environmental preservation.
