“…Generally, for PVD, semiconductors based on silicon are fabricated that reported as high as 25% photoenergy conversion efficiency 69 . While the solar cells based on the silicon are efficient enough for commercial applications, lack of flexibility and high cost of production hinders their suitability 70 . Hence, researchers are working towards developing an environmentally friendly solar‐cell technology that is produced easily and provides a higher efficiency in photoenergy conversion 71,72 .…”

Porphyrins have multiple roles in living and nonliving systems because of their exceptional tunable chemical and physical properties. They are interesting macrocyclic compounds that could be modified in a number of ways. The structural diversity of porphyrinoids make them a unique choice for functional devices exhibiting photo‐ and electrochemical properties. Their properties can be modified or altered by either protonating the nitrogen atoms or by inducing charge transfer to the metal center. Structural changes induced by flattening and planar distortions, redox reactions, solvents, and porphyrin aggregations also influence the photo‐ and electro‐chemical properties of porphyrinoids. This review gives a brief explanation on the effects of structural orientation, molecular structure, and charge on the properties of porphyrinoids. The review also illustrates the correlation between the geometrical features and the photo‐ and electrochemical behavior of porphyrinoids.

“…[3,4] However, despite having an efficiency that is good enough for commercial use, silicon-based solar cells have certain drawbacks like stability problems, high production costs, and a lack of flexibility. [5] Second-generation thin film PV cells are much more affordable, but their widespread application is constrained by inefficient performance. Perovskite solar cells (PSCs), which belong to this third generation of solar cells, [6][7][8] have gained popularity among researchers because of their quick increase in efficiency over the course of a decade.…”

In this paper, the encapsulating effect of single molecule of zinc porphyrin (Zn−P) inside semiconducting single walled carbon nanotubes (NT17) on the stability and optoelectronic properties of organic solar cells is investigated, assuming that this nano‐hybrid system will serve as the active layer in solar cell device. Making use of density functional theory (DFT), we looked at the optoelectronic characteristics of the isolated Zn−P molecules as well as two different configurations of the hybrid system that has a single Zn−P molecule inserted into NT17 (Zn−P@NT17 and Zn−P2@NT17). The addition of a zinc atom at the core of a porphyrin molecule results in the emergence of novel electronic and chemical characteristics, leading to distinct behavior compared to a free‐base porphyrin. These distinctions hold substantial implications for a range of applications, encompassing catalysis, sensing, and energy conversion processes. According to the study's outcomes, a charge transfer (CT) between the Zn−P molecules and the NT17 nanotube caused the structure to remain stable, and assuming to the electronic and optical computations the CT in Zn−P@NT17 hybrid nanosystems has been identified, along with its orientation. The results show that type II heterojunctions on filled semiconducting carbon nanotubes are likely to make them a viable choice for charge and light transport in the active layer, which can help create filled NT‐based OSCs that are extremely efficient.
