However, the high-transparency TOPVs with ultrathin active layers often suffer from substantial charge recombination, resulting in low power conversion efficiency (PCE). Here, we report a ternary strategy of introducing a UV-absorbing molecule (TPA-TPD) into near-infrared absorbing TOPVs, which can significantly suppress the charge recombination when reducing the thickness of the active layer in TOPVs. Due to its good miscibility and charge transfer properties with the receptors, the aggregation of the receptors was suppressed, and the active layer was preferentially oriented in face-on orientation. The prepared TOPV exhibits an efficiency of 1.03% with a record AVT of 89% and a CRI of 98.1.

Simultaneous measurements of solar cell characteristics and ESR demonstrated that the spin states in the hole-transporting layer change in accordance with the device-performance variation under operation.

For cost reduction, maximizing efficiency is paramount. Tandem solar cells, combining two absorbers with different band gaps, offer improved solar spectrum utilization. Hereby, a two-terminal configuration simplifies the layer structure but demands current matching. While the search for new, especially top absorber materials continues, we focus on fundamental tandem solar cell principles to emphasize key requirements. We analyze how top-cell transparency affects bottom-cell performance in stacked tandems. Imperfect transmission impacts the bottom cell, but in a current-matched device, even the top-cell efficiency. To match the bottom-cell performance, 50% top-cell transmission and 50% efficiency relative to the single bottom cell are required, but higher values to surpass it. Subgap transparency remains a critical challenge, underscoring the need for top-cell efficiencies approaching those of the bottom cell. To relax particularly current-matching constraints, concepts like luminescent coupling, wavelength-selective intermediate reflectors, or bifacial illumination may be considered. Operating under light concentration further enhances efficiency and better justifies tandem fabrication costs. Looking ahead, bifacial tandem concentrator cells, in a three-terminal configuration and combined with spectrum-splitting optics to reduce optical losses and improve adaptability to variable illumination, offer an innovative pathway.</p>","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 9","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202500060","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, parasitic resistance and optical losses must be reduced. In this respect, the impact of the chemical and electrical properties of the transparent conducting oxide (TCO) has somehow been overlooked. Considering the systematic reduction of the electron diffusion length as the low quasi-Fermi level regime is approached, subtle variations of the properties of the TiO₂ photoanode and its interaction with the TCO substrate can compromise optimal performance under indoor illumination. In this work, the performance of DSCs fabricated with commercial fluorine-doped tin oxide (FTO) and indium tin oxide (ITO) substrates, as well as newly prepared ITO substrates of varying conductivity, has been analysed. Furthermore, a variation of the preparation conditions for the TiO₂-based photoanodes was conducted, with thermal treatments at two different annealing temperatures (450 and 550°C). Photovoltaic characterisation and analysis of the impedance response reveal a low conductivity of the substrate proves to be only adverse under 1 sun illumination, deteriorating the fill factor due to the series resistance voltage drop. In contrast, under low illumination intensity, all studied substrates show comparable performance, which can be attributed to the negligible voltage drop over the series resistance related to the significantly lower photocurrent. As a consequence, the conductivity of the TCO substrate is less critical when selecting a substrate for indoor applications. However, the choice of TCO affects the quality of TiO₂ photoanodes, leading to shorter diffusion lengths in some cases. Interestingly, the annealing temperature plays a critical role in homogenising the differences observed while also enhancing the diffusion length, ensuring efficient electron collection under low light conditions.</p>","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 9","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143908880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
