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.

Our energy network, from high voltage to low voltage, is becoming increasingly complex. Economic and demographic growth requires more and more connections, while the energy transition makes those connections more demanding: houses need more electricity, but sometimes also deliver current back with solar panels. The result is an energy network that threatens to become completely congested in some places. Take the Buiksloterham neighbourhood in Amsterdam, for example. There, the medium-voltage network can no longer cope with growth, while local industry wants to expand and homes want to become more sustainable.
