Photovoltaic Materials and Devices
The program of the PVMD group builds up expertise in the design and fabrication technology of solar cells and other devices based on thin semiconductor films. The current focus is on amorphous and nano-crystalline silicon films fabricated at low temperatures (< 200 °C) using CVD (Chemical Vapour Deposition) techniques. The group specializes in applying advanced measurement techniques in combination with computer modeling for determination of (opto-) electronic properties, such as the density of defects in thin layers of disordered materials. The acquired expertise is used for the optimization of thin-film silicon solar cells and for the development of novel concepts using nano-structured materials for future high-efficient solar cells. A new research field of the group is directed towards the development of electronic components on flexible plastic substrates using thin-film silicon technology.

Four terminal perovskite-silicon PV tandem devices hit 30% efficiency
TNO, TU Eindhoven, imec and TU Delft – partners in Solliance – joined forces to further push the conversion efficiency of tandem solar cells to beyond the limits of today’s commercial photovoltaic (PV) modules. For the first time, four-terminal perovskite/silicon tandem devices with certified top cell pass the barrier of 30%. Such high efficiency enables more power per square meters and less cost per kWh.
