3 Red Flags in the Clean Energy Transition calling for more Material Efficiency
The transformation of our energy system from a fossil fuel-based to renewable-based system is key to limiting global warming to 1.5°C above pre-industrial levels. However, the massive and rapid expansion of renewable...

PV Module Power Increases with Improved Light Management
A novel system of optical elements redirects light so that the irradiance on the cells is increased, no light passes the pv module “unused” and more power is generated.

Printed in-situ Perovskite Solar Cells Save Resources and Can Be Produced Locally
In the past years, the cost of photovoltaics has fallen rapidly. Today the cost of electricity production from solar PV modules has become so low that PV is now cost competitive with fossil fuel energy sources. This...

Agrophotovoltaics: Harvesting the Sun for Power and Produce
An old German saying says that the dumbest farmer produces the biggest potatoes. Today we can say in contrast that the clever farmer harvests solar electricity. In Germany, solar electricity is about ten times more...

Photovoltaics – the ordinary madness
SolarWorld is only the latest bankrupt PV manufacturer in Germany. Many now wonder: What is the matter with photovoltaics in Germany and what is next? When trying to answer these questions, we have to look at three...

Software Reduces Losses in Solar PV Modules
A photovoltaic module consists of many interconnected solar cells. One cannot say, however, that the module power is simply the sum of the individual cells. Power losses due to reflection, absorption or electrical...

Agrophotovoltaics – Existing Solution for New Problems
Whether in Chile, Germany or somewhere else in the world – bringing home the harvest after a long working day is a satisfying feeling. As the German folk song “Im Märzen der Bauer” (In March the farmer) says: “He...
