It has been established that for OSCs SRH recombination dominantly affects short circuit current (<span>(:{J}_{sc})</span>), while for PSCs open circuit voltage (<span>(:{V}_{oc})</span>) is mostly affected, both resulting in a significant reduction of efficiency. Considering that one of the fundamental differences between organic materials and perovskites is the mobility of charge carriers, the influence of mobility on the loss of <span>(:{J}_{sc})</span> and <span>(:{V}_{oc})</span> due to SRH recombination in both types of solar cells was investigated. Higher <span>(:{V}_{oc})</span> and <span>(:{J}_{sc})</span> losses were observed in PSCs. The obtained results were explained by analyzing the operation of the devices in short-circuit and open-circuit. Unlike PSCs, in short-circuit of OSCs, a significant amount of charge carriers remains in the active layer. The pronounced SRH recombination appears which reduces the conductivity and therefore the drift current and consequently <span>(:{J}_{sc})</span>. At open circuit, in both OSCs and PSCs, the drift current balances the diffusion current which is found to be independent of SRH recombination. The decrease in conductivity therefore leads to an increase in the electric field, thus lowering <span>(:{V}_{oc})</span>. Obtained results are supported by experimental evidence from literature.</p></div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"132 11","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00340-026-08722-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149339623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intensity-dependent evolution of the SSPM patterns, particularly the increase in the number of concentric diffraction rings, was analyzed to determine the nonlinear refraction (NLR) coefficients of MEH-PPV and PBDB-T, yielding values of ~ 9.707 × 10<sup>− 11</sup> m<sup>2</sup>/W and ~ 1.281 × 10<sup>− 10</sup> m<sup>2</sup>/W, respectively.

The sensor features a fully symmetrical dual-core configuration with uniform air-hole diameters arranged in a hexagonal lattice, wherein two open-ring channels are incorporated on the D-shaped polished surface. One channel is coated with a gold (Au) film for RI sensing, while the other is filled with ‘polydimethylsiloxane (PDMS) + Au film’ mainly for temperature sensing, thereby effectively suppressing cross-sensitivity of the two sensing parameters. First, the finite element method (FEM) is employed to numerically optimize the structural parameters, within the optimized configuration, the proposed sensor can detect the RI and T simultaneously, with a range of 1.18–1.34 and − 40 °C to 100 °C, achieving a maximum RI sensitivity of 19,000 nm/RIU when RI is 1.34 and an average T sensitivity of − 0.5 nm/℃. Then, combining the sensitivity matrix decoupling method with the segmented fitting method, the detection accuracy of dual-parameter sensing has been effectively improved. Finally, a fabrication tolerance analysis confirms that a ± 10% variation in structural parameters exerts negligible influence on the resonance wavelength, demonstrating excellent robustness. Comparative analysis with previously reported dual-parameter sensors demonstrates that the proposed sensor provides competitive advantages in terms of wide low-RI detection range, broad temperature detecting range especially for low-temperature environment, and structural simplicity, making it highly promising for applications in gas sensing, chemical analysis, biomedicine, and low-temperature industrial monitoring.</p></div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"132 10","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00340-026-08723-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149133198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
