These organic HTL are chemically and thermally unstable, degrading when exposed to air and moisture. This work, for the first time, attempts to explore the possibility of replacing the conventional organic HTL with the thermally and chemically stable, high hole mobility, inorganic III-nitride p-InGaN material as an HTL in PSC. The p-InGaN HTL-based PSC achieved a power conversion efficiency (PCE) of 21.6%, which is reasonable when compared to the PCE of 32.9% and 34.5% delivered by the conventional organic Spiro-OMeTAD HTL and the HTL-free configurations. These can be attributed to the assisted hole extraction by the HTL and the direct contact of the MAPbI₃ perovskite absorber with the optimal higher work-function Pt back contact for the Spiro-OMeTAD HTL-based and HTL-free-based devices, respectively. We observed that variations in the back metal contact have a significant impact on the PCE of Spiro-OMeTAD HTL-based and HTL-free PSC, respectively. Although the p-InGaN and Spiro-OMeTAD HTL-based PSCs demonstrate equivalent values of PCE at all high temperatures, 400–700 K. The HTL-free cell shows higher thermal resilience compared to its HTL-based counterpart devices. Our work reveals that utilizing the p-InGaN HTL increases longevity due to material stability, whereas eliminating the HTL can deliver higher PCE and reduced costs.</div></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":"11 ","pages":"Article 100510"},"PeriodicalIF":0.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145981497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A catalyst for this transformation is the ability to manufacture autonomous lithium-ion batteries (LIBs), a vital component for EVs. Leading countries are competing to ensure an independent and autonomous supply of raw materials necessary for this energy shift, especially for nickel manganese cobalt oxide (NMC) chemistry, a significant cathode for LIBs. Morocco, a North African country, has a large production capacity for NMC raw materials, including nickel, manganese, and cobalt, but these resources are mostly exported in their raw or intermediate forms without significant valorisation to meet the NMC cathode requirements. To mitigate this challenge, this article develops refining processes that valorise actual mineral resources to produce the battery-grade precursors necessary for NMC cathodes. A rigorous examination of earlier studies found that sulphate precursors are the main metal sources used to make NMC cathodes in both research and industry. Refining processes have been established to transform natural manganese ore into a high-purity manganese sulphate precursor. Regarding nickel and cobalt sulphate, transformational processes were developed by adapting existing facilities. These processes will enable Morocco to produce 600 metric tonnes of nickel sulphate, 9305 metric tonnes of cobalt sulphate, and 56,160 metric tonnes of manganese sulphate, which in turn allows the manufacture of almost 370,000 EVs.

Though PCMs have been widely explored, their thermal control ability depends on the type of PCM, operation under constant/cyclic load, ambient temperature, etc. This study evaluates the suitability of different PCMs for thermal management of a battery pack (18 V, 7.2 Ah) under diverse operating conditions through a combined experimental and numerical approach. The operating parameters studied are charge/discharge at various C-rates, constant &amp; cyclic load profiles, PCM types, and ambient temperatures. The surface temperature and temperature non-uniformity of the battery module are monitored and compared under natural air convection, both without and with PCM cooling. The results showed that the use of PCM lowered the average battery pack temperature compared to air cooling, and achieved a reduction of 7 °C at 2 C discharging. Furthermore, the use of PCM improved the temperature non-uniformity of the battery module, limiting it to 4.5 °C during discharging at 2 C, which is 16.6 °C in natural convection. Under cyclic loading conditions, the use of PCM led to a significant temperature reduction of approximately 20 °C compared to natural convection. Moreover, numerical simulations reveal that Eicosane performs better at an ambient temperature of 30 °C, whereas 1-Hexadecanol is more effective at 40 °C. Additionally, results confirm that higher ambient temperatures adversely impact the battery surface temperature.

Three time series models, namely, exponential smoothing (Holt-Winters), autoregressive integrated moving average (ARIMA), and trigonometric seasonality, Box-Cox transformation, ARMA errors, trend, and seasonal components (TBATS) were employed to predict future emissions. The dataset was partitioned into training (1961–2012) and testing (2013–2022) sets to evaluate model performance.
