“…Among third-generation solar cells, dye-sensitized solar cells (DSSCs) have gained considerable attention owing to their inherent advantages, including low material cost, tunable optical properties, flexibility, and good performance in a wide range of lighting conditions [5,6]. Furthermore, recent advancements in bifacial DSSC technology have attracted considerable attention, enabling the absorption of sunlight from both front and rear sides [7].…”

“…One of the most common catalyst materials in DSSCs is platinum (Pt) due to its remarkable catalytic activity and high electrical conductivity [13]. However, Pt is prohibitively expensive, rare, and sensitive to contaminants [7], thereby limiting its widespread use in DSSCs. As such, the pragmatic deployment of DSSCs relies on the utilization of durable, recyclable, low-cost substrates with abundant and low-cost catalyst materials.…”

In dye-sensitized solar cells (DSSCs), the counter electrode (CE) plays a crucial role as an electron transfer agent and regenerator of the redox couple. Unlike conventional CEs that are generally made of glass-based substrates (e.g., FTO/glass), polymer substrates appear to be emerging candidates, owing to their intrinsic properties of lightweight, high durability, and low cost. Despite great promise, current manufacturing methods of CEs on polymeric substrates suffer from serious limitations, including low conductivity, scalability, process complexity, and the need for dedicated vacuum equipment. In the present study, we employ and evaluate a fully additive manufacturing route that can enable the fabrication of CEs for DSSCs in a high-throughput and eco-friendly manner with improved performance. The proposed approach sequentially comprises: (1) material extrusion 3-D printing of polymer substrate; (2) conductive surface metallization through cold spray particle deposition; and (3) over-coating of a thin-layer catalyzer with a graphite pencil. The fabricated electrodes are characterized in terms of microstructure, electrical conductivity, and photo-conversion efficiency. Owing to its promising electrical conductivity (8.5 × 104 S·m−1) and micro-rough surface structure (Ra ≈ 6.32 µm), the DSSCs with the additively manufactured CEs led to ≈2.5-times-higher photo-conversion efficiency than that of traditional CEs made of FTO/glass. The results of the study suggest that the proposed additive manufacturing approach can advance the field of DSSCs by addressing the limitations of conventional CE manufacturing platforms.

Dye-sensitized solar cells (DSSCs) have recently entered the market for indoor photovoltaics. Fast electron injection from dye to titania, the lifetime of the excited dye, and the suppression of back electron recombination at the photoanode/electrolyte interface are crucial for a high photocurrent conversion efficiency (PCE). This study presents block copolymers of poly(4vinylpyridine) and poly(styrene)-P4VP 67 -b-PSt x (x=23;61) as efficient accelerators of electron injection from dye to titania with extended lifetime excited states and long-lasting back electron recombination suppression. P4VP 67 -b-PSt 23 and P4VP 67 -b-PSt 61 rendered devices with PCEs of 10.0 and 9.8%, respectively, under AM 1.5G light; PCEs of 19.4 and 16.4% under 1000 lx LED light were attained. Copolymers provided a stable PCE with the two most popular I 3 − /3I − electrolytes based on ACN and 3methoxypropionitrile solvents; PCE history was tracked in the dark and under 1000 h of continuous light soaking with passive load according to ISOS-D1 and ISOS-L2 aging protocols, respectively. The impact of the polymer molecular structure on electron recombination, charge injection, dye anchoring, light absorption, photocurrent generation, and PCE and the long-term history of photovoltaic metrics are discussed.

Semi‐transparent perovskite solar cells (ST‐PSCs) offer a promising pathway for use in building integrated photovoltaic (BIPV) systems instead of conventional panels’ roofs. Furthermore, their potential for bifacial operation, allowing light absorption from both sides, creates new opportunities for their integration as solar cells windows, and greatly improves energy harvesting capacities. This combination of bifaciality and flexibility enhances their efficiency and adaptability, making them well‐suited for integration into various architectural elements. Herein, in this study, the performance of 40 different configurations of bifacial flexible semi‐transparent inverted perovskite solar cells (BF‐STIPSCs) is explored. Using SCAPS‐1D (version 3.3.11), a 3D‐perovskite (PVK) absorber layer is modeled and combined with polymer‐based electron transport layers (ETLs) such as C60 and BCP, along with innovative hole transport layers (HTLs) including D‐PBTTT‐14, Me‐4PACz, NiOx, PANI, Poly‐TPD, PATAA, SrCuO2, V2O5. Various transparent conductive oxides (TCOs) including IWO, ITO, and FTO, and flexible substrates such as silver nanowires (AgNWs) with two‐dimensional transition carbide (MXene: T2CF2) are also examined for their effects on the cells' bifaciality, transparency, and stability. Among the configurations, PET/Ag NWs:MXenes /SrCuO2/(FAPbI3)0.95(MAPbBr3)0.05/C60/BCP/FTO is identified as a high‐performance structure, achieving a power conversion efficiency (PCE) of ≈26%, along with enhanced resilience to temperature variations. These results hold great promise for the integration of perovskite‐based semitransparent bifacial flexible solar cells into real‐world applications.
