The organic contents of whey pose an environmental hazard and many governments now impose strict regulations requiring factories to pay for its treatment before disposal. Whey constitutes about 70% of the volume of the milk were used to make cheese. So, just one small feta facility will need ...
What are the main types of solar cells? Two main types of solar cells are used today: monocrystalline and polycrystalline. While there are other ways to make PV cells (for example, thin-film cells, organic cells, or perovskites), monocrystalline and polycrystalline solar cells (which are made...
New research reveals how solvent mixtures affect organic solar cell structureNorth Carolina State UniversityAdvanced Energy Materials
Composting doesn't have to be complicated. Here, experts list the ingredients and step-by-step instructions on how to make your own right at home, quickly.
Stick a solar cell in its path and it catches these energetic photons and converts them into a flow of electrons—an electric current. Each cell generates a few volts of electricity, so a solar panel's job is to combine the energy produced by many cells to make a useful amount of ...
How to Make a Soil-Urine Battery With Load: Is it possible to use earth or soil energy to power small homemade appliances? This research project gives an answer, although the battery endurance test is still in progress. A soilurine battery will not solve
how to get there were two different things entirely. Knowingwhereto go required inspiration or "color vision", i.e. some inherent, inborn talent, which in Western literature is consistently known as thesolarnexus, a.k.a.Thisbe or the Tishbite(an epithet ofElijah),Juliet("... and Juliet ...
To measure the amount of the grow light inside the grow tent, use aPAR Meter. Measuring light is important to ensure the optimal PPFD values to make plants thrive and yield. Using a PAR meter shows how much energy the grow light gives off and what lands on the plant. The optimal range...
The second part of the deposition process uses Physical-Vapor Deposition (PVD) through sputtering to apply ITO, forming the TCO layer of the heterojunction solar cell. An alternative process uses Reactive Plasma Deposition (RPD) to apply the TCO layer, but this is a less popular option. ...
Solar panels are made up of many small solar cells. These cells are made of semiconductor materials, like silicon. When sunlight hits the cell, it creates an electric field. This field causes electrons to flow from one side of the cell to the other. This flow of electrons generates electric...
