Integrating Radiative Coolers can Enhance Power Conversion Efficiency of Solar Cells

A solar cell converts light into electricity. So, the longer a solar cell remains out in the sun, the more power it can produce, right- Not necessarily. Solar cells capture massive amounts of heat during the day and their temperatures typically rise to tens of degrees greater than the ambient temperature of ~25 °C. The materials that solar cells are made of degrade at such high temperatures and overall, the performance of the solar cells fall.

Developmental Milestones of Photonic Matrix Multiplication and Related Applications

There has been an ever-growing demand for artificial intelligence and fifth-generation communications globally, resulting in very large computing power and memory requirements. The slowing down or even failure of Moore's law makes it increasingly difficult to improve their performance and energy efficiency by relying on advanced semiconductor technology. Optical devices can have a super-large bandwidth and low power consumption.

Challenges and Opportunities of Detecting Gravitational Waves at Much Higher Frequencies

Electromagnetic (EM) waves and gravitational waves are the only available means to study the Universe on a large scale. For millennia, only the former could be used, in naked-eye astronomical observations by the ancients based on the reception of visible light, or present-day super telescopes operating in various bands of the EM spectrum, from radio waves to gamma rays.

Scientists Open New Path Toward Producing Room-Temperature Superconductivity with Light

Much like people can learn more about themselves by stepping outside of their comfort zones, researchers can learn more about a system by giving it a jolt that makes it a little unstable – scientists call this "out of equilibrium" – and watching what happens as it settles back down into a more stable state.

Using Machine Learning and Raman Spectroscopy for Efficient Detection of COVID-19

The novel coronavirus, or SARS-CoV-2, which causes the highly contagious COVID-19, has infected millions of people worldwide. The global spread of this deadly pandemic has triggered widespread research on infection control. However, controlling the spread of COVID-19 is challenging for many reasons.
