The Effect of Irradiance (Solar Power!) on PV-Modules

Between Sunrise and Sunset, the Sun radiates good amounts of photons that illuminates the earth and distinguishes day from night. However, the photon from the Sun goes beyond physical light that brightens the day, it gives

Understanding Open-Circuit Voltage (Voc) & Short-Circuit Current

When purchasing or installing a solar module, or solar panel, there are various key specifications you must look at. Two such key specifications are Open-Circuit Voltage and

Theory of solar cells

However, the solar frequency spectrum approximates a black body spectrum at about 5,800 K, [1] and as such, much of the solar radiation reaching the Earth is composed of photons with energies greater than the band gap of silicon
