Organometallic complexes (OMCs) consisting of organic and metal active moieties have shown immense potential for application in solar cells. The diverse structure, rich porosity, and unique charge centers of OMCs enable them to be functional in solar cells. In this review, we introduced four types of OMCs, such as crown organometallic complexes, β-diketone metal complexes, cyclometallic complexes, and main chain metal-containing polymers, providing an in-depth analysis of the structure-performance relationship. OMCs could serve as active or interlayer materials in a variety of solar cell systems such as organic solar cells, perovskite solar cells, and dye-sensitized solar cells, especially some metals to improve the photoelectric performance of the device as dopants. In the end, perspectives on the opportunities and challenges of OMCs are given.

“…They can be categorized into following types: (a) Ru complex dyes, (b) metal free organic dyes, (c) quantum dot sensitizer, (d) perovskite based, (e) porphyrin, and (f) natural based photosensitizers. Ru(II) based sensitizers generally consist of a central metal ion with ancillary group , (e.g., bipyridines, terpyridines, or polypyridines and substituents such as alkyl, aryl heterocycle, carboxylate, etc. ), ligands , (e.g., monodentate (pyrazole, CN, and NCS), and bidentate (cyclometalated and noncyclometalated), and at least one anchoring group , (phosphonate and carboxylate).…”

Continual escalation of our world population demands a vast and safe energy supply, the majority of which has been produced by fossil fuel sources. However, because of the huge energy demand, exponential depletion of these nonrenewable energy sources is inescapable and forthcoming in the coming century. Hence, utilization of renewable energy such as solar energy has gained attention because of its direct conversion of light energy into electrical power without any harmful environmental impacts. Solar energy has been harvested by different types of solar cells varying from inorganic to organic to the combination of both. Among them, the dye-sensitized solar cell (DSSC) with a biopolymer-based electrolyte has gained enormous consideration from researchers because of its sustainability, abundance of available raw material, low production cost, and easy production in addition to the low volatilization of electrolytes compared to liquid state electrolytes. This review aims to give an overview of the recent inputs in the development of biopolymer-based DSSCs. The performance of the biopolymers as electrolytes in DSSCs will be critically reviewed based on the physicochemical properties of the biopolymers. Key technical challenges and future research areas for the advancement of biopolymer-based DSSCs are also discussed.

Summary During the recent period of time, dye sensitized solar cells (DSSCs) have become an exciting invention to meet our energy demands. Its reasonable cost of production and easy fabrication make it a powerful competent to the conventional solar cells. But non‐achievement of expected efficiency is the key challenge faced by the scientific society. To overcome this, boundless research is going on the revamping of DSSC. Among the four chief parts of DSSC, the photoanodes gain more attention due to its dual function. Scilicet, it act as a charge carrier and as a surface for dye adsorption as well. Hence photoanode modification plays a crucial role in enhancing the power conversion efficiencies of DSSCs. It comprises of wide bandgap semiconducting metal oxides, among which TiO2 stands out with higher efficiency. Likewise in the case of photosensitizers, metal complex based dyes (mainly ruthenium based) take the lead in augmented efficiency. This paper critically reviews the work on all the metal oxides used as photoanode materials, comparing their band gap with the best efficiencies reported for each and analyzing their advantages and disadvantages. An overview of the performance of DSSCs based on different metal atom doped metal oxide photoanode, incorporation of various carbonaceous materials and different passivating agents has been included. Also, the modification in the photosensitizer has been discussed, examining the reports on organometallics based dyes and metal free organic dyes.
