1. Introduction A photovoltaic/thermal hybrid solar system (or PVT system for simplicity) is a combination of photovoltaic (PV) and solar thermal components/systems which produce both electricity and heat from one integrated component or system. In other words, PV is used as (part of) the thermal absorber .

Combining the two technologies into one system is an attractive way to leverage space and potentially improve the overall solar energy utilization. Unfortunately, photovoltaics suffer from degradation in efficiency when operating at elevated temperatures, making their integration into hybrid systems challenging.
Scientific and engineering challenges of hybrid photovoltaic-thermal (PV-T) collectors. Research gaps and various pathways for innovation of PV-T collectors and systems. Design modifications, selective coatings, nanofluids and spectral splitting. Carbon mitigation potential and pathways for global decarbonization with PV-T collectors.
This hybrid system can take advantage of the complementary nature of solar and wind energy: solar panels produce more electricity during sunny days when the wind might not be blowing, and wind turbines can generate electricity at night or during cloudy days when solar panels are less effective.
Solar photovoltaic power systems Solar photovoltaic (PV) power systems are a cornerstone of renewable energy technology, converting sunlight into electrical energy through the PV effect. This process takes place in solar panels comprised of interconnected solar cells, usually made of silicon .

PVT collectors combine the generation of solar electricity and heat in a single component, and thus achieve a higher overall efficiency and better utilization of the solar spectrum than conventional PV modules. Photovoltaic cells typically reach an electrical efficiency between 15% and 20%, while the largest share of the solar spectrum (65% - 70%) is converted into hea…
