Air Mass (AM)

Air Mass (AM) Solar radiation of approximately 6000K is approximately a blackbody radiation. The energy of the radiation that reaches the top of Earth atmosphere is around 1353kW/m2. As it passes through the atmosphere, sunlight is attenuated by scattering and absorption. The more atmosphere sunlight passes, the more energy is attenuated. The spectrum outside the atmosphere is defined as AM0. Air Mass (AM) describes the relation of the length sunlight travels and spectrum and rad...

Getting Started with Measurements of Quantum Efficiency and IV Characteristics, Immediately Understand The Principles of Solar Cell

Solar cell is a device that, when being exposed to sunlight, generates voltage or electric current through photovoltaic effect. Solar cells are made with two types of semiconductors - p-type and n-type-to form a p-n junction. In the junction, electrons move toward the p-type side and holes move towards n-type side. This is where electric field is formed. When sunlight shines on solar cells, the energy of photons excites electrons to its conduction band. At this state, electrons can move freel...

Solar Spectral Irradiance: AM0, AM1.5G, AM1.5D

The American Society for Testing and Materials developed and defined the solar constant 1366.1 W/m2 u (also known as the total sky irradiance) and reference spectrum ASRM E490. This AM0 solar spectral irradiance is based on data from satellites, space shuttle missions, high-altitude aircraft, rocket soundings, ground-based solar telescopes, and modeled spectral irradiance. The reference spectrum ASRM E173 AM1.5G and AM1.5D provides terrestrial uses in simulating and evaluating photovo...

Characterization of tandem perovskite / organic solar cells

Characterization of tandem perovskite /organic solar cells Do you know there are almost 96% publications reporting tandem OPV characterizations characterized their devices insufficiently or even incorrectly!? The original article is as follows: To the Editor — The tandem solar cell approach is a promising concept for organic photovoltaics (OPVs). However, efficiency determination or, in general, electrical characterization of multi-junction solar cells is challenging. We performed a lit...

Xe Lamp Light Generation Mechanism

Xe Lamp Light Generation Mechanism Xenon short-arc lamps come in two distinct varieties: pure xenon, which contain only xenon gas; and xenon-mercury, which contain xenon gas and a small amount of mercury metal. In a pure xenon lamp, the majority of the light is generated within a tiny, pinpoint-sized cloud of plasma situated where the electron stream leaves the face of the cathode. The light generation volume is cone-shaped, and the luminous intensity falls off exponentially m...

What are QE and IPCE?

What are QE and IPCE? Quantum Efficiency, or IPCE (Incident Photon-to-electron Conversion Efficiency), is the conversion ratio of the incident photon to electron by a photovoltaic cell. For instance, if there are 100 photons irradiating on the surface of the solar cell and 80 electrons are generated, the Quantum Efficiency of the cell is 80%. Furthermore, because Quantum Efficiency is typically plotted as a curve related to wavelengths, it can also reflect the characteristics under variouw...
