“…Based on the composition used in dye, it is classified into three main categories viz. metal complex, metal-free organic complex, and natural sensitizer [63]. Ruthenium-based sensitizers are remarkable for achieving higher efficiency in dye-sensitized solar cells [64,65].…”

In this era the requirement for energy is enhancing, therefore, many energy resources are developed among them the emerging third-generation dye-sensitized solar cell is one of the environment-friendly solar cell-based technology. Generally, dye-sensitized solar cells consist of a nanomaterial-based photoanode, dye molecules as an absorber, electrolyte, and counter electrode. In the case of indoor application, this solar cell works easily so this is the characteristics of a dye-sensitized solar cell. Moreover, the outdoor performance of DSSC degrades on exposure to sunlight. Exposure to sunlight increases the temperature of the internal component of DSSC and consequently degradation in device performance. Long-term stability is obtained by the choice of such material where degradation takes place slowly and plastic covers are also coated over DSSC to prevent degradation. The solar response of DSSC towards dye was also mentioned, the higher the percentage of EQE higher the efficiency of the device. In this chapter, the authors discuss the introduction of a solar cell, the working principle of DSSC, and the available research background for outdoor performance and long-term stability with a solar response of device i.e. EQE or IPCE.

“…By applying Fermi-Dirac statistics which dictate that each discrete state can only be occupied by one particle, electron concentration in the conduction band can be expressed. Using this information, electric potential of the DSSC can be determined by solving Poisson's equation [23].…”

Dye-sensitised solar cells (DSSCs) are an important part of research on renewable energy sources as they are less complicated to manufacture and cost less than several other types of solar cells. The performance of DSSC with a combination of mesoporous zinc oxide and natural dyes are simulated using COMSOL Multiphysics. Numerical expression of the electrical properties of a dye-sensitised solar cell is applied to a two-dimensional structure to form an electrical model. Optical properties of the natural dyes are then coupled with this electrical model. The variables tested are thickness of the photoanode layer and absorption coefficient of dyes. Efficiency of the simulated zinc oxide solar cell with N719 dye is 12.4%. Maximum power of 0.309 µW is obtained at a photoanode thickness of 600 nm with current density of 16.815 mA/cm 2 and voltage of 0.756 V. The natural dyes simulated are chlorophyll, betalain and anthocyanin. Of the three, the one with the highest absorption coefficient i.e., betalain resulted in the highest efficiency solar cell. The results were more favourable than several simulations studying titanium dioxide based DSSC.

“…A numerical simulation platform known as Solar Cell Capacitance Simulator (SCAPS-1D) was used to predict the I-V characteristics of our DSSCs and to optimize the AgVO3doping concentration with respect to the output conversion efficiency. The input simulation parameters were extracted from the literature [1,[6][7][8]. During doping, Silver Vanadate (AgVO3) was introduced as extrinsic doping in the mesoporous layer, while the organic dye was treated as an absorbing layer with extinction properties from experimentally measured data.…”

The effectiveness of the mesoporous TiO2 layer, which acts as an active n-type semiconductor layer in dye sensitized solar cells (DSSCs) was investigated by varying the AgVO3-doping. To optimize the meso-superstructure, the doping concentration was varied from 0% to 25% using experimentally validated simulations. Moreover, performance comparisons between experimentally fabricated DSSCs based on natural beetroot and the commonly used N719 dye were made. A 15%doping concentration was found optimum for our DSSC, which delivered an output power of 19.24 mW, 6.1% power conversion efficiency, as well as an open circuit voltage, Voc, of 0.5 V and a short circuit current, Isc, of 21 mA/cm 2 in diffused light conditions. Based on these performance results, we integrated our optimized DSSC in an underwater sensing unit as a light harvester.
