Printed by NTNU Grafisk senter i This thesis concerns the use of solar energy in energy efficient buildings. More precisely, the topic is photovoltaic-thermal (PV/T) solar energy systems, and how these can be used to provide renewable energy in zero emission buildings. PV/T modules are a hybrid between photovoltaic (PV) modules and solar thermal collectors, and therefore generate electricity and thermal energy simultaneously. The objective of the thesis was to investigate the potential of PV/T systems to minimize the life cycle greenhouse gas emissions of a residential building.The building sector accounts for around one third of the global energy use and about half of the electricity use, and is therefore a key area to focus on in the effort to mitigate climate change and to create more sustainable societies in the future. The environmental impact of buildings need to be lowered by reducing the energy demand during construction and operation, but also by replacing polluting energy sources with renewable ones. The European Union has demanded of its member states that all new buildings shall be nearly zero energy buildings by 2020.Solar energy is well-suited to use in buildings, and can supply electricity, lighting, heating, and cooling. Once installed, a solar energy system supplies energy without pollution, is silent, have few or no moving parts, and can also be integrated into the building itself. In order to do investigate how PV/T systems can best be used in buildings to minimize life cycle emissions, the systems have been studied both in terms of energy performance and in terms of greenhouse gas emissions.The main research method in this thesis has been simulation of solar energy systems in buildings. Using simulations, PV/T systems have been compared to other solar energy systems with separate PV modules and solar thermal collectors. The simulation studies were performed in the simulation programs Polysun and PVsyst, and were based on commercial solar energy products available on the current market. The use of heat pumps, air-source and ground-source, in combination with solar energy systems was also studied.Two case buildings, the ZEB residential concept and the Living Lab, have been used in the simulation studies. The buildings are two of the pilot buildings of the Norwegian Research Centre for Zero Emission Buildings (the ZEB Centre). Both buildings are single family residential buildings located in Central or Southern Norway, and are designed to meet the Norwegian passive house requirements.The embodied emissions of the solar energy systems were determined using elements of life cycle assessments (LCA). A review of previous research found few studies of the environmental impact of PV/T modules, especially using industrially produced modules. The embodied emissions of such a PV/T module was therefore determined in this thesis, based on a combination of data from databases and information from module producers. The embodied emissions of the case buildings and the other solar energy systems studied were d...

“…Amorphous silicon is the most popular thin film technology used at low-and-medium temperature with cell efficiencies of 5-7%, and double-and triple-junction designs raising it to 8-10% [36]. The additional thermal efficiencies of flexible PV/T modules could be in the same range as observed for flat-plate modules at 22-79% [22]. A typical structure of flexible PV/T module is schematically illustrated in Fig.…”

Thermal absorbers and their integration methods are critical to solar photovoltaic/thermal (PV/T) modules. These two elements directly influence the cooling effort of PV layers and as a result, the related electrical/ thermal/overall efficiency. This paper conducts a critical review on the essential thermal absorbers and their integration methods for the currently-available PV modules for the purpose of producing the combined PV/T modules. A brief overview of different PV/T technologies is initially summarized, including aspects of their structure, efficiencies, thermal governing expressions and their applications. Seven different types of thermal absorbers and four corresponding integration methods are subsequently discussed and summarized in terms of their advantages/disadvantages and the associated application for various PV/T modules. Compared to traditional thermal absorbers, such as sheet-and-tube structure, rectangular tunnel with or without fins/ grooves and flat-plate tube, these four types, i.e. microchannel heat pipe array/heat mat, extruded heat exchanger, roll-bond heat exchanger and cotton wick structure, are promising due to the significant enhancement in terms of efficiency, structure, weight, and cost etc. The appropriate or suitable integration method varies in different cases, i.e. the ethylene-vinyl acetate (EVA) based lamination method seems the best option for integration of PV layer with thermal absorber when compared with other conventional methods, such as direct contact, thermal adhesive and mechanical fixing. Finally, suggestions for further research topics are proposed from five aspects. The overall research results would provide useful information for the assistance of further development of solar PV/T modules with high feasibility for widespread application in energy supply even at district or city-level in the near future.
