“…Notably, the achieved J sc values are 14–17% higher than those integrated from the IPCE curves (Table ). These results may be rationalized in terms of the following reasons: (1) the absorption and reflection by the FTO glass may lead to a loss of 10–15% in the IPCE; , (2) J sc may be enhanced due to the higher temperature associated with the full irradiation used for the J – V test; and 3) the full irradiation for the J – V test produces more electrons, leading to a higher charge transport/collection efficiency compared with the monochromatic light used in the IPCE measurement. , …”

Concerted companion dyes (CC dyes) like XW61 have been demonstrated to be an effective platform for developing efficient DSSCs. However, the moderated phenothiazine-based electron donor in XW61 results in unsatisfactory J sc. To address this problem, a stronger fluorenyl indoline-based electron donor has been used to construct porphyrin dye XW68 and organic dyes Y1–Y2. The stronger electron-donating character of the fluorenyl indoline unit leads to an enhanced J sc value (20.48 mA·cm–2) for the individual dye XW68. On this basis, CC dyes XW69–XW70-C8 have been designed and synthesized by combining the frameworks of Y1 and Y2 with XW68. The complementary absorption characters of the porphyrin and the organic dye moieties lead to panchromatic absorption with a strong light-harvesting capability from 350 to 700 nm and the onset wavelength extended to ca. 840 nm in the IPCE curves. As a result, excellent J sc values have been achieved (>22 mA·cm–2). In addition to the advantages of high J sc, bulky octyl groups have been introduced into the donor of XW70-C8 to reduce dye aggregation and suppress charge recombination. Finally, a highest PCE of 11.1% with a satisfactory J sc (22.25 mA·cm–2) and an enhanced V oc (750 mV) has been achieved upon coadsorption of XW70-C8 with CDCA. In addition, the CC dye XW70-C8-based solar cells exhibit excellent long-term photostability. These results provide an effective method for rationally improving the photovoltaic behavior, especially the J sc of CC dyes, by introducing strong electron donor moieties with suitable substituents.

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.
