Homework Statement Hey guys Concentrated photovoltaic systems are known for high efficiency performance compared to that of a standard solar panel. But, what's confusing me is the reason behind using lesser photovoltaic material in CPV systems. Can't we use the solar panel of the same size...

where v is the drift velocity of electrons, I is the current flowing through the material, n is the charge-carrier density, A is the area of cross-section of the material and q is the charge on the charge-carrier. Does the above equation imply that the more the velocity of an electron, the more...

What you mean by "fixed"? Mirrors are placed alongside a solar panel and are fixed.

I'm also wondering is there any specific angle at which the reflectors will be inclined so that they deflect the maximum amount of sunrays towards the solar panel? My intuition says it's around 45 degrees but I still need confirmed answers. Thanks

Sorry I couldn't find it. Maybe: current generated/intensity of incoming rays Also, if we are using mirrors to concentrate the solar energy then is there any specific angle at which the mirrors have to be placed in order to get maximum number of rays?

So I'm currently working on a project. Among the research questions, the following is one of them. "How can we use optical equipment such as mirrors to increase the output current?" I did some research into it but couldn't find its technical aspect. I know the straightforward fact that the...

Homework Statement How much percent can CPVs (Concentrated Photovoltaic cells) convert solar energy into electrical energy? Homework EquationsThe Attempt at a Solution According to this page, "http://www.benefits-of-recycling.com/solarenergycars-2/ ", 20% of solar energy is converted into...

Sounds good but doesn't electric motor needed to run a car? So solar panel will charge the batteries and batteries will in turn run a motor to convert electrical to mechanical energy. I haven't done much research on hybrid electric cars but do you think the idea I'm talking about refers to...

Makes sen Makes sense. But does solar car with (regenerative braking system) help reduce idling losses (when it is not running) or any engine losses?

Efficiency in the sense that it can overcome the losses mentioned in the link below: http://www.consumerenergycenter.org/transportation/consumer_tips/vehicle_energy_losses.html

reduction in weight compared to regular combustion engine cars but it still sounds technically correct? Because all I'm concerned about is increasing the efficiency of a car

Homework Statement For my ongoing project, I'm thinking of using Solar panels and Regenerative braking system as two main sources to charge the batteries that will run the motor and in turn the accessories of the car. Homework Equations I've to think of how can the above sources increase the...

Switch mode DC-DC converter and magnetic DC-DC converter. Both of them store their energy in magnetic field and thus the transformer. Thanks :) Just to make sure: So to convert from DC to AC, I'd have to use an inverter to make sure AC goes into the transformer. And an alternating...

I saw so many photos of the DC-DC converters and it looks really different from the transformers like it has diodes, capacitors and inductors. Is there any specific kind of DC-DC convert that functions as a transformer?

Thanks. I wonder if step down transformer can be used in place of DC/DC converter. And the principle it uses is mutual induction.
