This method works by putting a special voltage on the photovoltaic cells when it is dark. The cells then give off a weak infrared light. You can see cracks, broken cells, and other problems that you cannot see with your eyes. These problems include microcracks and cell damage. This includes a cell temperature of 25°C (77°F), light intensity of 1000 Watts per square meter (similar to noon sunlight), and an atmospheric density of 1. They help you measure open-circuit voltage (Voc), short-circuit current (Isc), and. .
