Spectral mismatch refers to the discrepancy between the spectral distribution of light sources used in experiments and the standard solar spectrum used for photovoltaic testing, impacting the accuracy of efficiency measurements. This phenomenon is crucial in assessing the real-world performance of solar cells, as it can lead to overestimation or underestimation of their efficiency when tested under non-standard conditions.

Spectral Mismatch

Spectral distribution describes how the power of a light source is distributed across different wavelengths, providing a detailed profile of its color characteristics. It is crucial for understanding the color rendering properties of light sources and their impact on visual perception in various applications such as photography, display technology, and lighting design.

Spectral Distribution

Light sources are objects that emit light, either through incandescence, fluorescence, or other processes, and are essential for visibility and various technological applications. Understanding their properties and mechanisms is crucial for fields ranging from physics and engineering to biology and art.

Light Sources

The standard solar spectrum represents the distribution of solar radiation across different wavelengths as it reaches the Earth's atmosphere, serving as a critical reference for solar energy applications and atmospheric studies. It encapsulates the intensity of sunlight at various wavelengths, providing a baseline for comparing solar irradiance under different atmospheric conditions.
