Achieving peak efficiency requires closely matched current generation in all junctions, especially in integrated configurations. However, real-world conditions vary significantly due to factors such as sunlight spectrum, diffuse-to-direct sunlight ratio, angular distribution of light, subcell temperature coefficients, and ground reflection. This study introduces a comprehensive optical and device simulation to optimize perovskite/silicon tandem cells, considering experimental luminescent coupling (LC) efficiency and its dependence on working conditions, alongside variations in radiative recombination, effect of temperature on absorptivity spectra, and cloud cover. Our results show potential energy yield improvements of up to 1.4 % with LC, based on current perovskite radiative recombination records, and up to 4 % with direct bandgap materials. Although radiative recombination's dependence on excitation intensity reduces output power and requires thicker absorbers, LC compensates for these losses. LC also lowers the optimized bandgap for the perovskite top cell from 1.72 eV to 1.64–1.68 eV, or even lower in regions with redshifted irradiance. Additionally, optimization revealed that thinner silicon bottom cells require a higher perovskite top cell bandgap, impacting the balance between fabrication cost and cell stability.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"290 ","pages":"Article 113730"},"PeriodicalIF":6.3,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144105524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, laser-structured screens with a polyimide (PI) barrier layer have gained prominence due to their significantly higher lifetime. In this work, we build upon the state-of-the-art by creating a prototype screen comprising of a new liquid photopolymer barrier layer, combined with conventional PI, resulting in a ‘hybrid barrier layer’. The aim of this work was to laser structure a full grid layout on the prototype and determine whether the hybrid barrier layer offers additional benefits, such as narrower fingers with reduced paste spreading. We successfully lasered a busbarless grid layout comprising of 120 fingers onto the prototype screen. This process was completed in just 10 minutes, and the laser-structured screen openings were tapered. For comparison, we used an industry standard screen coated only with PI as a reference. The average printed contact width of the prototype was approximately 23 μm, comparable to the average 21 μm of the reference. Also, a low wet silver laydown of 9 mg was applied to print the front side cell layout. The core widths of the printed fingers were measured to be 18 μm for the prototype and 16 μm for the reference screen. Both screens exhibited paste spreading of 5 μm.

A major concern is, however, that the minority carrier lifetime (lifetime) of silicon solar cells degrades severely under high-energy electron irradiation. Fortunately, thermal and hydrogenation processes can potentially recover all the irradiation losses. This work studies these defects and their recovery using contactless lifetime measurement and deep-level transient spectroscopy (DLTS). Both fired and unfired Ga-doped passivated emitter and rear contact (PERC) solar cell precursors are used in this work. The precursors were irradiated with 1 MeV electrons and annealed at 300 °C and 380 °C, respectively. All the samples exhibited lifetime recovery, with fired samples recovering faster and achieving higher saturated lifetime. After ∼360s of annealing at 380 °C, the irradiated fired samples recovered to their pre-irradiation lifetime, whereas the irradiated non-fired samples required 71.5 times longer (25,740 s). Remarkably, longer annealing caused reductions in lifetime, likely due to surface-related degradation. The DLTS measurements revealed a clear reduction of recombination-active defects after annealing, including V-V<sup>+</sup> and C<sub>i</sub>-C<sub>s</sub> in irradiated fired samples and V-V<sup>+</sup> in irradiated unfired samples. This study demonstrates that the firing process is critical for optimizing the recovery of irradiation damage in silicon solar cells. Hydrogenation of the silicon bulk results in quicker recovery and superior End-of-life performance compared to thermal recovery without hydrogen. Therefore, Ga PERC with bulk hydrogenation can recover radiation-induced damage, rendering it suitable for LEO missions.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"290 ","pages":"Article 113729"},"PeriodicalIF":6.3,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144089793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
