Scientists turn carbon emissions into usable energy

A recent study affiliated with UNIST has developed a system that produces electricity and hydrogen (H2) while eliminating carbon dioxide (CO2), the main contributor of global warming. This breakthrough has been led by Professor ...

New class of solar cells, using lead-free perovskite materials

Lead-based perovskites are promising materials for low-cost and high-efficiency solar cells. However, the intrinsic instability and the toxicity of lead (Pb) have raised serious concerns of the viability of Pb-based perovskites, ...

Shining light on recombination mechanisms in solar cell materials

Hybrid perovskites are spectacularly efficient materials for photovoltaics. Just a few years after the first solar cells were fabricated, they have already achieved solar conversion efficiencies greater than 22 percent. Interestingly, ...

Does saving energy save the climate?

To stop climate change, saving energy matters less than switching to renewable energy. Indeed, says Anthony Patt, it isn't clear whether saving energy makes much of a difference at all.
