In this paper, the localized hot-spot phenomena within a unit solar cell are experimentally examined and the transient forming and variation processes of localized hot spots resulted from different mechanisms are explored, which are seldom reported to the best of our knowledge.
However, we discovered that the solar cell is likely to have hotspots if affected by crack mode 3 or 4, with an expected increase in the temperature from 25 \ (^\circ \) C to 100 \ (^\circ \) C. Additionally, we have noticed that an increase in the shading ratio in solar cells can cause severe hotspots.
In a photovoltaic (PV) module, a hot spot describes an over proportional heating of a single solar cell or a cell part compared to the surrounding cells. It is a typical degradation mode in PV modules. Hot spots can origin, if one solar cell, or just a part of it, produces less carrier compared to the other cells connected in series.
The large-scale hot-spot phenomena may develop from localized temperatures anomaly within a unit cell in the module while current researches generally ignored this small-scale but important problem. In this paper, close inspection of localized hot spots within photovoltaic modules is conducted with a xenon lamp of simulating the solar irradiation.
Among the most critical of these inefficiencies are the thermal anomalies known as hotspots. These hotspots represent zones of elevated temperature localized within specific areas of a PV module, which can cause substantial increases in the temperature of solar cells, consequently impacting the module's overall performance.
The genesis of hotspots is often linked to physical defects, such as micro-cracks within the solar cells, as documented in the literature , , . Such defects intrinsically hinder thermal uniformity because they can create localized areas of increased resistance, which the mitigation circuit cannot physically rectify.
