6 FAQs about [Solar red light power generation]

Can 'night-time' solar power produce electricity?

UNSW researchers have made a major breakthrough in renewable energy technology by producing electricity from so-called ‘night-time’ solar power. The team from the School of Photovoltaic and Renewable Energy Engineering generated electricity from heat radiated as infrared light, in the same way as the Earth cools by radiating into space at night.

Do solar cells use infrared light?

Standard photovoltaic solar cells (PV cells) use only about half of the light spectrum provided by the sun. The infrared part is not utilized to produce electricity. Instead, the infrared light heats up the PV cells and thereby decreases the efficiency of the cell.

Can solar cells convert light into electricity?

A/Prof. Ekins-Daukes likens the new research to the work of engineers at Bell Labs who demonstrated the first practical silicon solar cell in 1954. That first silicon solar cell was only around 2% efficient, but now modern-day cells are able to convert around 23% of the sun’s light into electricity.

Could solar energy be harnessed in the Dark of night?

The sun's enormous energy may soon be harnessed in the dark of night following a significant advance in thermal capture technology. Solar radiation heats the earth's crust significantly during daylight hours, but that energy is lost into the coldness of space when the sun goes down.

Could nighttime solar cells replace existing energy infrastructure?

The nighttime solar cells have the potential to be useful in off-grid locations for certain low-power tasks, but they are unlikely to replace existing energy infrastructure. However, Fan and his team say the set-up could be improved to generate more power.

How do we convert solar energy into electricity?

“Whenever there is a flow of energy, we can convert it between different forms,” he said. “Photovoltaics, the direct conversion of sunlight into electricity, is an artificial process that humans have developed in order to convert the solar energy into power.
