The growth of global energy demand and the aggravation of environmental pollution have prompted the rapid development of renewable energy

in which the solar photovoltaic/thermal (PV/T) heat pump system

as a technology integrating photovoltaic power generation and thermal energy conversion

has also ushered in the development and challenges. This paper reviews the relevant literature in detail

and solar PV/T heat pump technology is overviewed from three perspectives. Photovoltaic/thermal collectors are classified into three main types: air-cooled

liquid-cooled

and heat pipe. The advantages and disadvantages of different collectors and applicable scenarios are analyzed. The system energy efficiency

performance enhancement

and optimization strategies of the new coupled system established by PV/T technology and different heat pump technologies are discussed

emphasizing the potential of PV/T heat pump systems in improving the comprehensive energy utilization efficiency

energy saving

and emission reduction. The impact of the outdoor environment and regional applicability on the performance of collector components and systems are analyzed

and the technical

environmental

and market challenges facing the system were identified. Finally

future trends in PV/T heat pump technology are outlined

including technological innovation

cost reduction

and market expansion

as well as their importance in the global energy transition. The results of this study indicate that PV/T heat pump systems play an important role in achieving green and sustainable development; however

further technological breakthroughs and market promotion are still needed.
