Source: Little Scientists · Auf Lager Understanding Photon Absorption in Semiconductors When photons with energy equal to or greater than the band gap of a material interact with the material, they can excite an electron into the conduction band. This process generates both minority and majority carriers, forming the basis of photovoltaic energy production. Interaction of Photons…
Source: Understanding Global Change Absorption in the Atmosphere As solar radiation travels through the atmosphere, various gases, dust, and aerosols absorb the incoming photons. Certain gases such as ozone, carbon dioxide, and water vapor have high absorption capacities for photons with energies close to their bond energies. This absorption leads to significant dips in the…
Source: Mineralienatlas Tin(II) Sulfide (SnS): A Comprehensive Overview Crystal Structure and Forms Tin(II) Sulfide (SnS) is a brown solid that is insoluble in water. In nature, it occurs as herzenbergite, which possesses an orthorhombic crystal structure. Additionally, SnS can exist in hexagonal (wurtzite) and cubic (Sphalerite) crystal forms, although these are less stable than herzenbergite…
Source: Clever Solar Power The Importance of Battery Voltage in Electronic Devices Understanding Battery Voltage The voltage of a battery is a crucial characteristic determined by the chemical reactions, component concentrations, and polarization within the battery. The nominal battery voltage is the voltage calculated under equilibrium conditions. While it is challenging to measure the nominal…
Source: YouTube Battery Capacity and Its Factors Battery capacity is a crucial metric that indicates the amount of charge a battery can store. It is typically measured in Ampere-hours (Ah) and represents the maximum energy that can be extracted from the battery under specific conditions. However, the actual energy storage capacity of a battery can…
Source: Shindengen Semiconductor Materials: An Overview Semiconductor materials play a crucial role in various technological applications, including photovoltaic (PV) systems. These materials are derived from different groups in the periodic table, each offering unique properties and characteristics that are essential for their functionality. Classification of Semiconductor Materials Semiconductor materials primarily consist of elements from group…
Source: Museum Of Solar Energy Understanding Multicrystalline Silicon for Solar Cells When it comes to producing silicon for solar cells, there are two main techniques: single crystal and multicrystalline silicon. Multicrystalline silicon is favored for its simplicity and cost-effectiveness compared to single crystal silicon. However, the material quality of multicrystalline silicon is lower due to…

By introducing specific impurities into a semiconductor material, it is possible to control the number of electrons and holes within the material, thereby altering its electrical…
Source: International Atomic Energy Agency Solar Irradiance in Space When sunlight travels through space, the solar irradiance, which is the power density incident on an object due to illumination from the sun, decreases as the object moves further away from the sun. This phenomenon occurs because the total power emitted by the sun is spread…
Source: Syed Ovais Akhtar – Medium Understanding PV Modules in Remote Power Applications A photovoltaic (PV) module is a unit comprising interconnected solar cells encapsulated to form a durable and stable structure. The primary purpose of encapsulating solar cells is to shield them and their interconnecting wires from the harsh environmental conditions they are exposed…
