“…However, efficiencies that were reported in subsequent studies did not improve any further, and they ranged from 1–5.5% at most [340,341,342,343,344]. In 2014, Amalina and Rusop conducted an investigation into the properties of CuI thin films [340].…”

“…Hanif et al in 2017 modified CuI by adding TMED (tetramethylethylenediamine) and NH 4 SCN (ammonium thiocyanate) in the fabrication of ss-DSSCs [344]. The study included several volume variations of TMED (0.1, 0.2, and 0.4 mL) and mixing ratios of TMED:NH 4 SCN (1:1, 1:2, 2:1) .…”

“…CuI with simple TMED (0.4 mL) exhibited a conductivity of 0.29 S m −1 , whereas the corresponding value with added TMED:NH 4 SCN (2:1) was 0.39 S m −1 and that with pristine CuI was 0.26 S m −1 . The fabricated ss-DSSC consisted of nanorods of TiO 2 on the photoanodes that were sensitized by N3 dye, followed by the HTM layer, and lastly platinum as a CE [344]. The performance of ss-DSSCs with the HTM based on pure CuI resulted in a PCE of 0.46%, whereas the cells containing CuI-TMED had an efficiency of 0.9%, and those with CuI-TMED:NH 4 SCN exhibited the highest efficiency of 1.52%.…”

“…Hence, the highest efficiency was 3.28 times higher when CuI was dissolved in TMED:NH 4 SCN than when pure. Therefore, the combination of TMED and NH 4 SCN with CuI is integral to improved optical and electrical properties of ss-DSSCs employing CuI [344].…”

Dye-sensitized solar cells (DSSCs) have been intensely researched for more than two decades. Electrolyte formulations are one of the bottlenecks to their successful commercialization, since these result in trade-offs between the photovoltaic performance and long-term performance stability. The corrosive nature of the redox shuttles in the electrolytes is an additional limitation for industrial-scale production of DSSCs, especially with low cost metallic electrodes. Numerous electrolyte formulations have been developed and tested in various DSSC configurations to address the aforementioned challenges. Here, we comprehensively review the progress on the development and application of electrolytes for DSSCs. We particularly focus on the improvements that have been made in different types of electrolytes, which result in enhanced photovoltaic performance and long-term device stability of DSSCs. Several recently introduced electrolyte materials are reviewed, and the role of electrolytes in different DSSC device designs is critically assessed. To sum up, we provide an overview of recent trends in research on electrolytes for DSSCs and highlight the advantages and limitations of recently reported novel electrolyte compositions for producing low-cost and industrially scalable solar cell technology.

“…Mainly, the optical and electrical properties of CuI can be tuned through the synthesis and preparation conditions. Several studies show the successful utilization of γ-CuI as a hole transport layer in solid-state dye-sensitized [ 14 ], organic solar cells [ 15 ] and perovskite solar cells [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ], due to their band-matching and hole transporting properties. These show that a CuI hole-transporter not only enhances the power conversion efficiency but also improves charge extraction and stability.…”

Thermally Evaporated Copper Iodide Hole-Transporter for Stable CdS/CdTe Thin-Film Solar Cells

et al. 2022

This study focuses on fabricating efficient CdS/CdTe thin-film solar cells with thermally evaporated cuprous iodide (CuI) as hole-transporting material (HTM) by replacing Cu back contact in conventional CdS/CdTe solar cells to avoid Cu diffusion. In this study, a simple thermal evaporation method was used for the CuI deposition. The current-voltage characteristic of devices with CuI films of thickness 5 nm to 30 nm was examined under illuminations of 100 mW/cm2 (1 sun) with an Air Mass (AM) of 1.5 filter. A CdS/CdTe solar cell device with thermally evaporated CuI/Au showed power conversion efficiency (PCE) of 6.92% with JSC, VOC, and FF of 21.98 mA/cm2, 0.64 V, and 0.49 under optimized fabrication conditions. Moreover, stability studies show that fabricated CdS/CdTe thin-film solar cells with CuI hole-transporters have better stability than CdS/CdTe thin-film solar cells with Cu/Au back contacts. The significant increase in FF and, hence, PCE, and the stability of CdS/CdTe solar cells with CuI, reveals that Cu diffusion could be avoided by replacing Cu with CuI, which provides good band alignment with CdTe, as confirmed by XPS. Such an electronic band structure alignment allows smooth hole transport from CdTe to CuI, which acts as an electron reflector. Hence, CuI is a promising alternative stable hole-transporter for CdS/CdTe thin-film solar cells that increases the PCE and stability.
