All-perovskite tandem solar cell boasts high efficiency, record voltage

Engineers have developed a new solar cell with a record voltage and (arguably) a record efficiency for its kind. The all-perovskite tandem solar cell uses two layers of perovskite that tap into different wavelengths of light, plus a special surface tre… Continue reading All-perovskite tandem solar cell boasts high efficiency, record voltage

Solid-state refrigerant works under pressure for greener cooling

As useful as refrigerators and air conditioners are, the gases they use as refrigerants can leak into the atmosphere and become major contributors to climate change. Now engineers at Harvard have demonstrated a new prototype cooling device that uses a … Continue reading Solid-state refrigerant works under pressure for greener cooling

Perovskite-silicon solar cells break 30% efficiency barrier

Scientists have broken the efficiency record for tandem silicon-perovskite solar cells, surpassing the milestone of 30 percent for the first time. The new record takes the technology beyond the upper limits of silicon alone, using low-cost and scalable… Continue reading Perovskite-silicon solar cells break 30% efficiency barrier

First perovskite solar cell to cross 30-year expected lifespan

Perovskite is poised to become a major material for solar cells, but before then it needs to overcome a major durability issue. Engineers at Princeton have unveiled a new perovskite solar cell design that tests suggest could last as long as 30 years of… Continue reading First perovskite solar cell to cross 30-year expected lifespan

Simple fix helps perovskite solar cells withstand the Sun

Perovskite materials are quickly emerging as a promising candidate for solar cells, but one of their major downsides is that they can degrade in direct sunlight. Researchers at UCLA have now uncovered a root cause of the problem, and found a simple fix… Continue reading Simple fix helps perovskite solar cells withstand the Sun
