A solar cell (or a "photovoltaic" cell) is a device that converts photons from the sun (solar light) into electricity. In general, a solar cell that includes both solar and nonsolar sources of light (such as photons from incandescent bulbs) is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics.

MIT researchers designed a computationally efficient algorithm for machine learning with symmetric data that also requires fewer data for training than conventional approaches. Their work could inform the design of faster, more accurate machine-learning models for tasks like discovering new drugs or identifying astronomical phenomena.

Simulating extraterrestrial environments on Earth has always been a challenge. Our planet has a pleasant atmosphere, reasonable temperatures, and a moderate amount of gravity, unlike the rest of the solar system. Or maybe that’s just because we think that way because we adapted to how it is here as we evolved here. In either case, the physical environment here makes it difficult for us to set up test environments that can accurately test probes going to other parts of the solar system. Many times, it involves vacuum chambers, air conditioners and heaters pumping hot and cold air into them, and soil simulant - lots and lots of soil simulant. But, according to a new paper from researchers at the University of Wisconsin-Madison, we’ve been neglecting one important aspect of these tests, and it might be the reason Spirit eventually got permanently stuck on Mars - sand is affected by gravity too.
