Solar Panels Background and Literature Review Solar cells require the use of anti-reflection coatings (ARC) that consist of one or more thin films carefully chosen for their thicknesses and refractive indexes in order to minimise reflection losses caused by common solar cell materials such as silicon, which suffers an approximate 30% loss without the use of ARC due to its high refractive index (n ≈ 3.5 – 4, in typical operation range of 400 to 1100 nm)[1],[7]. Existing ARC materials (e.g. silicon nitride, silicon oxide) are mostly oxide-based (except silicon nitride) and are prone to premature aging, UV-induced degradation, and the added complexity and cost associated with requiring protective encapsulation of such materials [2].  Hexagonal boron nitride (h-BN) is deemed a suitable alternative ARC material as h-BN is a wide-bandgap (~6.2 eV) [3] 2D material with a refractive index of approximately 2.23 [4], along with high chemical/thermal stability, and excellent mechanical robust...

Various Discrete Power MOSFETs In modern electrical and electronic systems, the Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) is one of the most important and widely used semiconductor devices. Its high input impedance, fast switching capability, and low power consumption offer significant advantages over conventional Bipolar Junction Transistors (BJTs), making it the dominant switching device in applications ranging from low-power digital circuits to high-power energy conversion systems. Ever since its introduction in the 1960s, the MOSFET has undergone continuous structural refinement, with power-focused variants emerging from the 1970s onward to meet increasingly demanding requirements for efficiency, power handling capability, and switching speed. The progression from planar MOSFETs to VMOS, DMOS, trench-gate, split/shield-gate, and superjunction technologies reflects a series of engineering solutions aimed at reducing conduction losses while maintaining high breakdown...

Improved Boost Converter Circuit ⚠️ Important Safety Notice This post is for educational demonstration only. While I have years of experience in electronics, this circuit involves high-voltage switching systems that can be dangerous if mismanaged. Please read the Full Safety Disclaimer at the bottom of this post before considering any practical work. This post is a sequel to the previous post on boost converters. If you have not read the first post, I strongly recommend reading it first, as it explains the theory of operation covered in this post. You can read the first post here . In the previous post, we constructed a simple boost converter on a breadboard. The results, however, were not particularly impressive. In this post, the circuit has been redesigned with improved components, and this time we will be driving an actual load rather than just a resistor.  Updated Circuit Schematic Since the theory of operation was already covered in the previous post, the focus here will be o...

A Basic Boost Converter Circuit ⚠️ Important Safety Notice This post is for educational demonstration only. While I have years of experience in electronics, this circuit involves high-voltage switching systems that can be dangerous if mismanaged. Please read the Full Safety Disclaimer at the bottom of this post before considering any practical work. Nowadays, everyone is talking about renewable energies. People can't resist the cool, sleek looking solar panels and massive wind turbines that the government has placed all across the country in order to harvest "clean" energy, albeit only working in certain time or location (solar panels need sunlight and wind turbines need a location that's susceptible to wind) and takes up quite a lot of space (solar/wind farms. One single panel/turbine is not gonna power a country), renewables are still deemed the future of power generation, as fossil fuels are indeed turning earth into a massive rotating sweatbox. But of course, I...
