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...

Perovskite-based LEDs are making rapid progress! EQE up to 20.1% comparable to OLEDs

To improve the brightness, contrast and resolution of the display, while reducing costs and the usage of limited resources, scientists have developed different kinds of light-emitting diodes, such as organic light-emitting diodes (OLEDs), quantum dots LEDs (QLEDs), perovskite-based LEDs (PVSK LEDs) and micro LEDs. Compared to OLEDs, which are widely used in high-end consumer-electronics, the external quantum efficiency of perovskite-based LEDs has rapidly been improved from 0.76 % to 20.7 % in...

Solvent-controlled growth of inorganic perovskite films in dry environment for efficient and stable solar cells

Is the inorganic perovskite solar cell a trend in the future? In the highly competitive solar industry, perovskite solar cells have leapt toward commercialization, and challenged the silicon solar cells holding the largest market share at present. Perovskite solar cells have high optical absorption, low cost compared with silicon solar cells, and can be dissolved in solvent and then spray coated directly onto substrate. If its instability and deterioration on exposure to heat problems can ...

How to analyze the defects in perovskite devices and measure diode ideality factor?

Understanding the I-V characteristic of the internal structure of device is fundamental to develop a highly efficient and highly stable solar cell. When measuring I-V characteristic in a p-n diode one needs to consider the diffusion current, recombination current and series resistance effects, which could result in the device’s performance. Therefore, researchers could know whether the device is parallel to an ideal diode by calculating the ideality factor η. The ideality factor η is a numbe...
