The Invention History of Fuel Cells

Without energy, would anything exist in the world? Living organisms like you and me and the flora and the fauna require some form of energy to survive. A bike, car, motor, television, everything requires some energy to start up, accelerate and even to stop. Thus, form of energy required for the survival or for the sustainability is termed as the fuel energy. The fuel may be any form of energy. Say for example, the food we consume may be either made of carbohydrates, proteins or even fats which can be converted to the storage form glycogen. Similarly, any form of…

Invention History of Phototransistor and Photodiode

Before touching the main topic of the invention history of the phototransistors, it is important to have a basic understanding on what phototransistors and photodiodes are. In simple words, a phototransistor is a transistor operated by light rather than electric current. In brief, a phototransistor is a bipolar transistor enclosed in a transparent case so that light can reach the base collector junction. This being the case of phototransistors, a photodiode is a kind of photo detector that is capable of converting light into either current or voltage based on the mode of operation. To understand it better, a traditional…
