Atomic layer deposited (ALD)-SnOx is well suited as an ETL for tandem devices due to its ability to uniformly coat textured surfaces, but its high density of defects significantly limits efficiency compared to conventional solution-processed SnOx.

In this study, we introduced N-(2-phenoxyethyl) guanidine nitrate salt (NPEGN) as a surface passivator to effectively engineer surface defects and reduce nonradiative recombination at the interface. The NPEGN introduction on the perovskite surface results in large grains with fewer grain boundaries, leading to the formation of low-dimensional 2D phase on the perovskite surface. Furthermore, NPEGN treatment passivates defects through ionic and hydrogen bonding with perovskite and inhibits perovskite degradation by preventing ion migration. Additionally, improved energy-level alignment at the perovskite/electron transport layer interface enhances charge transport capacity and reduces charge recombination. Consequently, the efficiency of perovskite solar cells with NPEGN treatment increases to 21.02%, while the unencapsulated devices retained 100% of their initial power conversion efficiency for 2200 h in nitrogen atmosphere and 90% of their initial efficiency for 450 h at 65°C.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 7","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762109","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}

However, Br-rich WBG devices still suffer from poor morphology, significant open-circuit voltage (VOC) loss, and instability due to their rapid crystallization and defect-rich nature to date. Herein, an amino acid derivative additive, N-(Chloroacetyl)glycine ethyl ester (CGEE), is introduced to address the above challenges. It is found that CGEE effectively regulates the pace of perovskite crystal growth through dual interactions with PbI2 and FAI. Furthermore, the carbonyl group of CGEE passivates perovskite defects, therefore suppressing nonradiative recombination and enhancing stability of the devices. By leveraging the multifunctional properties of CGEE, it can retard crystallization process, mitigate film stress, improve interfacial energetic alignment, and passivate lattice defects. With these merits, small-area inverted devices achieved a champion efficiency of 22.23% (compared to 20.68% in control device) and an exceptional fill factor of 85.59%, with negligible efficiency decay over 1000 h observation period. Additionally, a 5 × 5 cm mini-module with an effective area of 12.8 cm2 is fabricated, exhibiting good uniformity and achieving a champion efficiency of 16.4%.

These approaches mitigate trap states and recombination losses, significantly enhancing device efficiency and long-term stability. This study investigates the impact of surface passivation on the PSC performance by employing iodide-based passivators—phenethylammonium iodide (PEAI), octylammonium iodide (OAI), and guanidinium iodide (GUI)—alongside the Lewis base molecule 1,3-bis(diphenylphosphino)propane (DPPP), which, to the best of our knowledge, is introduced for the first time in n-i-p structured PSCs. SEM and XRD analyses revealed that DPPP-passivated samples exhibited superior morphological and structural stability after long-term ambient aging compared to other passivations. Under indoor 1000 Lx LED light illumination, the DPPP-passivated device achieved an iPCE of 33.14%, closely approaching the highest iPCE of 34.47% obtained with PEAI. Furthermore, the DPPP-passivated device demonstrated the highest stability under thermal stress (85°C) with a T80 of 753 h.

In industrial TOPCon cells, the high-temperature firing process during metal contact formation degrades the passivation quality of poly-Si/SiOx contacts, necessitating improvements to maintain cell performance. While previous studies examine degradation factors related to the rear structure, research on mechanisms driven by the firing process remains limited. This study identifies how excess hydrogen, rather than phosphorus in-diffusion, degrades passivation quality by diffusing from SiNx into SiOx during the firing process. Thermal stress during the firing process dissociates c-Si/SiOx bonds, while interstitial hydrogen accumulates at the SiOx interface and forms hydrogen pores as defects, reducing passivation quality. To mitigate this, we introduce an Al2O3 layer as a hydrogen diffusion barrier, effectively preventing hydrogen diffusion into SiOx. This approach increases the implied open-circuit voltage (iVoc) after firing, achieving a record 729.8 mV with Al2O3/SiNx double passivation layers. These findings advance the understanding of degradation mechanisms in industrial TOPCon solar cells during firing and offer practical strategies for optimizing industrial-scale solar cell manufacturing.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 6","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688823","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}
