Fabrication and performance evaluation of dye-sensitized solar cell integrated with natural dye from Strobilanthes cusia under different counter-electrode materials

Recent Progress, Advancements, and Efficiency Improvement Techniques of Natural Plant Pigment‐Based Photosensitizers for Dye‐Sensitized Solar Cells

“…In the same manner, 0.13% of PCE was produced when graphite was used as CE while lotus leaf extract photosensitizermodified TiO 2 -FTO photoanode [48]. It can be concluded that graphite presents feasible potential as an alternative to platinum due to its affordable cost and performance output due to having more than 0.0385% efficiency than FTO glass and platinum by using Strobilanthes cusia photosensitizer [49]. Kumar et al [50] designed and fabricated a new costeffective, enhanced performance CE using a carbon material produced with the organic ligand 2-methyl-8hydroxyquinolinol (Mq).…”

“…A ruthenium-based dye and platinum are the most common materials used as photosensitizer and counterelectrode, respectively, in the production of the DSSCs, the third generation of photovoltaic technologies. However, their expensive cost, the complexity and toxicity of ruthenium dye, and the scarcity of platinum sources preclude their use in the DSSCs [49]. Thus, an alternative way to produce cost-effective dyes on a large scale is by extracting natural dyes from plant sources.…”

“…The dependence on renewable energy resources including wind energy, hydro energy, solar energy, biomass, biofuels, and geothermal energy has increased. Among them, solar energy has attracted the attention of researchers, academics, industrialists and policy makers most because of its outstanding properties such as being environmentally friendly, simply exploitable, inexhaustible, renewable, cost‐effective, non‐contaminating and adaptable to various applications [2–7] . To harness solar energy effectively, many technologies are used; photovoltaic (PV) cells and concentrating solar power (CSP) are the most commercialized among them.…”

[2][3][4][5][6][7] To harness solar energy effectively, many technologies are used; photovoltaic (PV) cells and concentrating solar power (CSP) are the most commercialized among them. In uninhabited places, CSP appears to be slightly more advantageous, whereas photovoltaics are preferred in humid areas.…”
