Electrical Characteristics of a Solar Cell/PV Module
Abstract: Conventionally, a PV system consists of solar PV arrays and electric converters. A PV array is formed by series/parallel combination of solar modules. Some operating conditions result in non-uniform irradiance of PV array, such as shadows, clouds, dirt, debris, bird droppings, different orientations and tilts, and so on. If several solar cells in a series PV module are mismatched due to non-uniform irradiance, these cells will limit the output current …

Examination of the Amplitude Equation to the Characteristics of Harmonic Oscillators: The Concept of Schrodinger Wave Equation
Abstract: Although Heisenberg’s matrix mechanics was developed first, the Schrödinger equation was the first useful quantum wave equation. However, the Schrödinger equation is applicable only to non-relativistic cases. As opposed to classical physics, where the wave equation can be derived from first principles, in quantum physics the wave equation is obtained by a plausibility argument based on classical physics and the de Broglie hypotheses. Inserting the de Broglie relations. A frequently …
