Solar cells are made from semiconductors whose ability to respond to light is determined by their band gaps (energy gaps). Different colors have different energies, and no single semiconductor has a ...

Solar power is already one of the fastest growing sources of electricity on the planet, yet scientists say it is still only ...

(Nanowerk News) The sunlight received by Earth is a mixed bag of wavelengths ranging from ultraviolet to visible to infrared. Each wavelength carries inherent energy that, if effectively harnessed, ...

A novel dye-sensitized photocatalyst developed at Science Tokyo enables the capture of long-wavelength visible light for efficient hydrogen conversion, surpassing conventional photocatalysts.

Japan is pushing solar hydrogen into a new phase by teaching its materials to drink in colors of sunlight that used to go to ...

Researchers have created a dye-sensitized photocatalyst that captures long-wavelength visible light to double solar hydrogen ...

Researchers in Canada have conducted a series of simulations to understand how spectrum splitters may raise the efficiency of two-terminal tandem solar cells and have found that efficiency gains may ...

Solar filters emit a red light over tomato plants growing in a research field at UC Davis in 2022. The work further tests the findings of a UC Davis study showing plants in agrivoltaic systems respond ...
