Thermal runaway in solar cells that can cause cells to fail has been reported. 1–8) Excess generated current that cannot be output to the external circuit under forward bias operation, such as an open circuit condition, flows back to the local shunt spot (i.e. the local low resistance region) 9) of the solar cell. This backflow leads to localized heating, and the …
What Causes Thermal Runaway? (Fact Sheet)
Faults in a lithium-ion cell can result in thermal runaway, a phenomenon in which the lithium-ion cell enters an uncontrollable, self-heating state – potentially resulting in extremely high temperatures, smoke and fire. These faults can be caused by internal failure or external conditions. Download this resource to learn more.
