The p-n junction under forward bias

Let’s take our present knowledge of a P-N junction one step further and see what happens when we apply a voltage to the junction. This is a schematic picture of a P-N junction with electrodes attached to it. With the attachment of electrodes the P-N junction has become an operational device that we call a […]

Microgen – Renewable

This is Greg. And he probably spends more time thinking about your power outlets than you ever have or ever will. Microgeneration is the idea that people can make their own clean power, use what they need and sell what they don’t. As the director of development at an energy company, you might think this […]

What If We Burn All the Oil?

. What could you do to stop this giant fire tornado? Or anchor this floating house? Or keep these portable toilets from flying away? If your answer is “probably nothing,” then you’re just like most of us who stare blankly at images like these on our screens every day. Sure, we know that these are […]

How Electric Vehicle Batteries Could Be Used to Power Entire Cities

If you thought the future was about driving electric cars, then you’re in for a shock. What’s the most valuable thing inside an EV? It’s not the motor. It’s the battery. That battery, depending on its size, can power an individual household for up to a week. It’s like a mobile power plant that could […]

How does the electricity-free Coolar refrigerator work?

Hi I’m Christoph one of the co-founders of Coolar This fridge is going to a field test today and before we send it out I’ll explain to you exactly how it works This Coolar fridge runs completely without electricity Instead it uses solar heat to run a sorption cooling cycle in this way it can […]

SAVE OUR PLANET – Steep global temperature increase from continued fossil fuel burning

Beyond Fossil Fuels: Sustainable Industry Immersion – UC Davis Graduate School of Management

And you get that opportunity to actually talk to the speaker at a personal level and that’s something that you never, ever get. The Industry Immersion Program is unique at UC Davis. Now that I have graduated, the Immersion Program has been something that I always reminisce back to. I had the opportunity to speak […]

How does an inverter and MPPT of a PV system Work? – Sustainable Energy – TU Delft

The solar inverter is one of the most important power electronic devices that makes the modern PV system widely usable. It makes the DC power from the modules usable for all the appliances in our house. Although these appliances might internally either work with DC or AC, all of them are used to an AC […]

Status and prospects of PV Technology – Sustainable Energy – TU Delft

What is the current status of Solar energy? To gain some insight into the current status, I would like to discuss the production of solar modules. We will consider different aspects of the production, starting off with the annual installation of PV technology. This figure shows the global annually installed peak power, in GWp, as […]
