Global warming is an environmental issue that threatens life on Earth. A significant rise in global temperature at the end of the century is estimated to be 2.4 ◦C, which necessitates action. The growth of energy needs urges scholars/researchers to think about developing suitable solutions. The key goal is to achieve zero-net emissions by 2050 in accordance with the goals outlined in the Paris Agreement (Climate Accords). To accomplish this, it is vital to have a strong strategy that initially includes high emissions reduction goals and addresses the challenges of global warming on our planet. Therefore, by 2050, the global energy strategy aims to eliminate emissions from the energy industry to zero. It is worth noting that most energy of the energy consumed comes from transport, power generation, industry, and buildings. The use of renewable technology is a method that is widely recommended to eliminate such challenges. Solar energy has two main technologies: solar photovoltaic (PV) and concentrating solar power (CSP), which have great potential in fulfilling energy needs. This work provides insight into solar energy technology’s role in global decarbonisation and towards net-zero emissions by 2050 through wide deployment and energy yield. The perspectives of solar energy technologies can save the environment by reducing emissions and energy supply, lowering energy bills, and creating job opportunities. Hence, investment in solar energy and other clean energy technologies will substantially achieve sustainable development in the coming decades; as forecasted, solar energy will have great installation capacity worldwide.

Dye-sensitized solar cells (DSSCs) play a significant role in the development of affordable, safe, and efficient solar energy technology. In this research, we have designed nine new dyes (J01-09) by modifying an experimentally reported thiophene-based dye (DSS) in the literature. The diethylaniline in the DSS as the electron donating group was replaced with diphenylamine to reduce planarity in the dye. The designed dyes all have donor and acceptor groups linked by a π-linker group (D-π-A). Using DFT and TD-DFT, we investigated the impact of the diphenylamine moieties on the planarity, photochemical and photophysical properties of the modeled dyes in isolation. The optimized structures, UV–Vis absorption, photochemical, and photovoltaic parameters were computed to study the photosensitizing capability of the modeled dyes. The photochemical and photovoltaic parameters of the study include; open-circuit voltage (V OC), light-harvesting efficiency (LHE), driving force of electron injection (ΔGinj), driving force of regeneration (ΔGreg), excited-state lifetime (τ), ionization potential (IP), adiabatic ionization potential (AIP), vertical ionization potential (VIP), electron affinity (EA), chemical hardness (η), electrophilicity index (ω), electron-donating power (ω-) and electron-accepting power (ω+) were calculated. Our findings indicate that only J03 and J08 absorb at longer wavelengths (719 and 753 nm respectively) indicating lower absorption energy bandgap compared to the DSS dye, attributed to the extension of conjugation between the thiophene and donor groups. Also, only J03 and J08 exhibited lower ΔGinj values (−0.985 and −0.667 eV respectively) and ΔGreg values (0.245 and 0.179 eV respectively) implying the dyes can be regenerated spontaneously compared to the DSS dye. Therefore, J03 and J08 are more promising to be developed as a superior photosensitizer in DSSCs. [ABSTRACT FROM AUTHOR]
