Answer the following statement(s) true (T) or false (F)
1. When photons are absorbed by a photovoltaic cell, the energy decreases the mobility of electrons in the semiconductor material. 2. The amount of device current in a photovoltaic cell is directly proportional to cell size (surface area) and solar radiation intensity (watts per square meter). 3. An assembly of photovoltaic cells mounted on a panel is called an array. 4. As temperature decreases (gets colder), device voltage increases, and as temperature increases (gets warmer), the voltage decreases. 5. Some of the most common standard test conditions are: Solar intensity (irradiance) = 1000 watts / square meter Cell temperature = 25 degrees C
