Key Highlights
•
Researchers have mapped the specific ways that formamidinium–caesium (FACs) perovskite solar cells break down under heat and light, revealing distinct failure modes at different temperatures. This understanding is crucial for designing more durable solar panels that can last for decades in real-world conditions.

A new perspective clarifies that the electric fields and potentials in a standard semiconductor solar cell junction are identical to the initial, non-equilibrium conditions created by light, provided the light is absorbed evenly. This fundamental insight helps bridge the gap between textbook physics and the complex operation of real-world devices for generating electricity and fuels from sunlight.

A detailed study of Australia’s Eromanga Basin has identified a specific sandstone formation that could be a viable geothermal aquifer, with areas holding enough in-place thermal energy to theoretically generate an average of 164 megawatts of heat. This work de-risks geothermal exploration by pinpointing where hot, porous rock exists, offering a potential path for consistent, clean baseload power.

The research combined seismic data and well logs to map a prospective zone where the Hutton Sandstone is over 50 meters thick, exceeds 120°C, and has good porosity, key ingredients for a successful geothermal reservoir. This integrated approach provides a blueprint for evaluating similar sedimentary basins worldwide for geothermal potential.
