In the experiment, perovskite solar cells were repeatedly cooled to minus 150 degrees Celsius and then heated to plus 150 degrees Celsius. The changes in the microstructure of the perovskite layer and ...

When temperatures increase, most materials tend to expand, causing a change in material dimensions. When two materials that exhibit different thermal expansion behaviors are in direct contact, such as ...

Thermal management deals with problems arising from heat dissipation, thermal stresses and warping. It is critical in the packaging of power semiconductors and other microelectronic and optoelectronic ...

From home labs to mission-critical electronics, stress testing reveals weaknesses before they cause costly downtime. By simulating extreme conditions, engineers and hobbyists alike can prepare for ...
