Design and Optimization of Concentrated Photovoltaic-Thermal Systems for Solar Hydrogen Production Monash University Malaysia in Malaysia

Green hydrogen production through solar-powered water electrolysis is a critical pathway for global decarbonisation. Conventional photovoltaic-electrolyser systems often waste substantial thermal energy generated during operation, limiting overall efficiency. Concentrated photovoltaic-thermal (CPVT) systems address this challenge by simultaneously generating electrical power and recoverable high-grade thermal energy from solar input. While CPVT technology is promising in regions with high direct normal irradiance, adapting these systems for tropical and equatorial climates—where diffuse radiation is significant—remains a key research challenge. Additionally, optimal strategies for thermal energy harvesting and integration with hydrogen production systems are not fully explored.

This PhD project at Monash University Malaysia focuses on the design, modelling, and optimisation of advanced CPVT systems for solar hydrogen production. The research will emphasise optical system design, thermal management strategies, and multi-physics modelling to develop high-efficiency CPVT architectures capable of operating under variable irradiance conditions. A major objective is to investigate how CPVT-generated thermal energy can be strategically utilised to enhance water electrolysis performance and improve system economics.

The project is predominantly simulation and modelling-based, with scope for targeted experimental validation. Key research areas include:

• Design and characterisation of CPVT system configurations for hydrogen production
• Development of multi-physics simulation models capturing optical, thermal, and electrical behaviour
• Investigation of thermal management and photovoltaic cooling strategies
• Analysis of thermal energy utilisation pathways for water electrolysis
• System-level performance optimisation and parametric analysis
• Numerical investigation of CPVT system performance under various conditions
• Techno-economic assessment and performance evaluation of CPVT-based hydrogen production systems

Advanced numerical simulation and multi-physics modelling are primary methodologies. Geometry modelling, optical modelling, computational fluid dynamics, electrical circuit modelling, and electrochemical performance models will be integrated to capture coupled system behaviour. Simulation platforms such as EES, MATLAB/Simulink, Python, ANSYS/COMSOL, or similar tools will be used extensively. Physics-informed machine learning approaches may be applied to accelerate model development, performance prediction, and system optimisation.
