Individual solar cell devices are often the electical building blocks of photovoltaic modules, known colloquially as solar panels. As the current production also depends upon the surface area of the cell exposed to light, it is better to express maximum current density instead maximum current. Solar Cell Operation. 1. Photovoltaic Science and Engineering Conf., pp. Organic solar cells have increased in efficiency over the past decades, but researchers and manufacturers still struggle with determining which material combinations work best and why, as well as with achieving stable morphology and operation. Solar cell maximum power PM depends upon the voltage that it develops across the cell terminal and the current it can supply. When the light falls on an angle greater or lesser than 90o some part of the light is reflected, and the light utilized by the cell less than the actual falling on it.
