Seventy-two publications are classified into three methodological families: artificial neural networks (ANNs), ensemble methods, and other ML techniques. The review is augmented with a patent landscape for liquid-based PV/T technologies and an evaluation of the experimental basis used to build the reviewed ML models. Results show ANNs lead PV/T modeling (63%), while ensemble models such as Random Forest and XGBoost reach the highest accuracies (R² up to 0.999), and most studies report R² above 0.95.","Journal Pre-proofs  \nA comprehensive review of machine learning applications in liquid-based cooling solutions of PV/T systems  \nKrzysztof Rajski, Mirosław Żukowski, Alina Żabnieńska-Góra, Hussam Jouhara  \nPII: S2451-9049(26)00154-X  \nDOI: [https://doi.org/10.1016/j.tsep.2026.104628](https://doi.org/10.1016/j.tsep.2026.104628)  \nReference: TSEP 104628  \nTo appear in: Thermal Science and Engineering Progress  \nReceived Date: 4 November 2025  \nRevised Date: 23 February 2026  \nAccepted Date: 7 March 2026  \nPlease cite this article as: K.

A total of 72 publications are analyzed and categorized across three methodological families: artificial neural networks (ANNs), ensemble methods, and other ML techniques. The review is complemented by a patent landscape analysis covering liquid-based PV/T technologies and a critical assessment of the experimental foundations underlying the reviewed ML models.  \nThe analysis reveals that ANNs dominate PV/T modeling at 63% of reviewed studies, with Multilayer Perceptron being the most
