A research team has developed a highly efficient tandem solar cell composed of perovskite and organic absorbers which can be produced at a lower cost than conventional solar cells made of silicon. The further development of this technology is expected to make solar energy even more sustainable. A ...
Harvesting energy from the temperature difference between photovoltaic cell, surrounding air leads to a viable, renewable source of electricity at night
About 750 million people in the world do not have access to electricity at night. Solar cells provide power during the day, but saving energy for later use requires substantial battery storage. In Applied Physics Letters, by AIP Publishing, researchers from Stanford University constructed a ...
Reliably determine the mobility and lifetime of the charge carriers in new semiconducting materials
Many semiconducting materials are possible candidates for solar cells. In recent years, perovskite semiconductors in particular have attracted attention, as they are both inexpensive and easy to process and enable high efficiencies. Now a study with 15 participating research institutions shows ...
So-called PERC cells are used in mass production of silicon solar cells, they are considered the workhorses of photovoltaics, dominating the market. Now two teams from HZB and the Institute for Solar Energy Research in Hamelin (ISFH) have shown that such standard silicon cells are also suitable ...
Producing materials for solar cells, light-emitting diodes and other organic electronics applications as sustainably as possible
Some hikers carry a small solar power plant with them: a foil is attached to their backpack that converts sunlight into electricity. This allows them to charge their mobile phone while on the move. Flexible, thin and lightweight solar panels can also be attached to outdoor clothing or glued to ...
Around ten thousand tons of silicon in discarded photovoltaic modules end up on the recycling market annually in Germany. This figure will rise to several hundred thousand tons per year by 2029. Currently, the aluminum, glass and copper of the discarded modules are reprocessed, however, the ...
Several layers of nanographenes stacked on top of each other: such functional elements could one day be used in solar cells
Graphene is a carbon material that forms extremely thin layers. Because of its unusual properties, it is interesting for many technical applications. This also applies to polycyclic aromatic hydrocarbons (PAHs), which can be regarded as cut-outs of graphene. They are considered promising ...
Additional light emission is achieved by recursively recycling trapped photons in perovskites
Scientists from TU Dresden, in cooperation with researchers at Seoul National University (SNU) and Korea University (KU), demonstrated the role of the re-use of photons (known as ‘photon recycling’) and light scattering effects in perovskite solar cells, providing a pathway towards ...
Success through high throughput
Perovskites are the great hope for further increasing the efficiency of solar modules in the future. Until now, their short service life has been considered the biggest hurdle to their practical use, but this could soon change. In the current issue of the journal Nature Energy, researchers from ...
Novel method to fabricate lead halide perovskite solar cells with record efficiency
In a joint effort between Pavia University (Italy) and the Center for Advancing Electronics Dresden at Technische Universität Dresden (Germany), researchers developed a novel method to fabricate lead halide perovskite solar cells with record efficiency. Metal halide perovskites have been under ...
