We present data exhibiting hot spots spontaneously emerging in forward biased thin film photovoltaics based on a-Si:H technology. These spots evolve over time shrinking in their diameter and increasing temperature up to approximately 300 $^o$C above that of the surrounding area. Our numerical approach explores a system of many identical diodes in parallel connected through the resistive electrode and through thermal connectors, a model which couples electric and thermal processes. The modeling… 
Modeling of temperature profile, thermal runaway and hot spot in thin film solar cells
Abstract Hot spot and thermal runaway are serious phenomena leading to the degradation of CdTe thin film solar cells. Here, we show that these issues are well related to temperature variation in the

Experimental observations on hot-spots and derived acceptance/rejection criteria
The IES–UPM observations on 200 affected photovoltaic modules are presented, as well as electroluminescence, peak power rating and operating voltage tests have been carried out, and hot-spots temperature gradients larger than 20 °C are proposed as rejecting conditions for routine inspections under contractual frameworks.
This paper deals with the occurrence of hot-spot phenomenon in photovoltaic systems under PV partial shadowing. In an experimental campaign, the hot-spot phenomenon was revealed on a PV installation
