The contact resistivity ( $\rho _c$ ) of screen-printed contacts is a significant component of series resistance in industrial solar cells. Measuring $\rho _c$ with standard techniques, such as the transmission line method (TLM), requires that the cu

UV Fluorescence (UVF) is a relatively new "non-contact" method of detecting cracked cells in solar panels with potential high throughput and low cost. We report here on application of a pole-mount UV-flash camera system to the detection of defects on

Solar panel degradation is usually assessed by the change in power at standard testing conditions (STC). However, some degradation mechanisms have shunting or recombination characteristics which have the potential to reduce performance at low irradia

The transmission line method (TLM) is often used in characterizing the contact resistance of c-Si solar cells by cutting cells into strips parallel to the busbars. When applying this method to industrial solar cells, we found various problems that ha

A single brief exposure of a photovoltaic (PV) module or coupon to cold temperatures down to -40°C, the lower limit in IEC photovoltaic testing standards, significantly degrades the fracture strength of silicon solar cells. To understand the mechani

Solar panels generally contact the mounting structure only along the surfaces of the aluminum frame surrounding the perimeter of the panel. With no support in the middle of the panel, front side mechanical loads from snow, wind, and human factors can

Existing mechanical durability testing sequences typically perform mechanical loading prior to environmental exposures such as thermal cycling or humidity freeze. Recent work has shown that the fracture strength of silicon solar cells can reduce afte
