Purpose The purpose of this paper is to investigate the chemical, optical and photovoltaic properties of titanium dioxide/reduced graphene oxide (TiO2/rGO) photoanodes immersed in natural Roselle and synthetic (N719) dyes for dye-sensitized solar cell (DSSC) application. Design/methodology/approach TiO2 mixed with rGO were doctor-bladed on fluorine doped tin oxide (FTO) glass substrate. The chemical and optical properties of TiO2/rGO photoanodes immersed in Roselle and N719 dyes were characterized using Fourier-transformed infrared (FTIR) and ultraviolet–visible (UV–vis) spectroscopies, respectively. The DSSC’s photovoltaic performances were tested using Visiontec Solar I-V tester at standard illumination of AM1.5 and irradiance level of 100 mW/cm2. Findings The presence of anthocyanin dye from Roselle flower was detected at 604 nm and 718 nm. TiO2/rGO+Roselle dye sample revealed the smallest energy gap of 0.17 eV for ease of electron movement from valence band to conduction band. The TiO2/rGO-based DSSC fabricated with Roselle dye had a power conversion efficiency, ƞ of 0.743 per cent higher than TiO2/rGO photoanode sensitized with N719 dye (0.334 per cent). The obtained J-V curves were analyzed by a single-diode model of Lambert W-function and manual optimization to determine the internal electrical parameters of the DSSC. The average and uncertainty values of Jsc and ƞ were evaluated at different Rsh range of 1362 Ω to 32 k Ω. Research limitations/implications Rs values were kept constant during optimization work. Originality/value New ideality factor of TiO2/rGO-based DSSC was re-determined around 0.9995.

“…A new type of material based on hybrid perovskites (organic‐metal halides, hybrid) compositions gained attention as a top cell material joining the Si solar cells. [ 40–46 ] However, the hybrid perovskite solar cells are currently facing stability and Pb‐toxicity challenges, and serious efforts are in progress across the globe to address them. [ 46–50 ] On observing all these existing technologies and associated challenges, one can conclude that further research is needed to develop new tandem solar cell materials suitable for utility and residential/commercial installations similar to today's mainstream PV s. Though developing an utterly new multijunction/tandem combination is approachable for the long run, a more practical and quick solution is to make the tandem configuration with the existing solar cell technologies.…”

This review points out the current need for further research on tandem solar cells as the commercial single‐junction solar cell technologies report close to their maximum performance limit. First, the conceptual insight and the desired interconnection schemes for tandem solar cells are briefly presented. Then, a comprehensive discussion on the structural, optical, and electronic properties of CuGaSe2, evaluating its use as a top cell absorber material, is presented. Furthermore, the current status and the critical analysis of CuGaSe2 solar cells, which finds that the adapted conventional device architecture possesses severe limitations, are presented. Based on the drawbacks of the existing materials in use, new materials to fabricate CuGaSe2 solar cells are proposed. Also, tandem configurations with newly proposed CuGaSe2 solar cell architecture by choosing Si photovoltaics as bottom cells are devised. In the end, further challenges in the devised tandem configurations with a focus on their band alignments are elucidated.
