Careful design of the materials in the cell stack allowed researchers at the National Renewable Energy Laboratory (NREL) of the US Department of Energy to extract a little more efficiency from their ...

A research group from Spain has investigated the impact of temperature and spectral conditions on III-V solar cells operating under ultra-high concentration (UHC) conditions. Gallium arsenide (GaAs) ...

The cells used copper metallisation paste in place of silver. Image: Fraunhofer ISE. Scientists at the Fraunhofer Institute for Solar Energy Systems (ISE) have developed a new heterojunction ...

Next-generation solar materials are cheaper and more sustainable to produce than traditional silicon solar cells, but hurdles remain in making the devices durable enough to withstand real-world ...

Fraunhofer ISE researchers utilized a new front metallization technique to produce a III-V gallium arsenide solar cell. For mask and plate front metallization, they used a new two-step printing scheme ...

Silicon heterojunction solar cells combine crystalline silicon substrates with thin amorphous silicon layers to harness the advantages of both materials. This approach yields superior passivation, ...

Without a significant reduction in silver content, the global demand for photovoltaics to ensure a sustainable, climate-neutral energy system cannot be met. Scientists at the Fraunhofer Institute for ...
