هلوو اكو احد عربي هنا؟ اني من العراق وعلم الكيمياء يلي ندرسه في العراق تحتوي هذا الموضوع بس ما عدنا تطبيق عملي فلذلك يصعب عليي توصيل المعلومه فا ابحث عن هذه التجارب الكيميائية حتى يتيسر علي الحفظ

When doping p-type junction...??? During silicon metaling process or after after texturing process...??

What if you skipped the high purity and went straight to creating a crystalline structure? Would it still be able to perform the same uses, just at lower efficiency?

Thanks

Thank you

Thanks

fantastic explanation, thank you so much, helped in studying for finals!

How quaint. It's funny looking back at these adoption numbers now that we produce this much solar every 3 months.

I don't know why an alcoholic early 30s man wanted to make this video essay, but it was highly informative!

MPPT is not unique to PV cells/arrays, it applies equally to hydro generation and wind generation although, in the latter case, the response time may need to be shorter/quicker.

Thank you sir, you explained it so clearly, whatever the doubts I was having it is cleared with your animations

Very good video, most other videos stop at how to produce metallurgical silicon

👋

thank you

Learned a lot, thanks, i'm going to make 0.5micron chips now

Excellent piece of presentation! Clear and to the point 👏

BOMBE!!!!

Take a drink every time he lip smacks

so that is what happened to the water that was on mars.

Great video to explain MPPT methods. As you noted there are other methods ---9yrs later it would be interesting to hear what some of the other techniques or methods are ----> Please do a follow-up video. Also it would help if you could clarify why and by how much Imp > Isc.

Thanks for your teaching 😊😊😊. Amazing lesson 🎉

Very helpful thank you. Im looking for a simpler solution. Say a potentiometer thats lets you set the voltage while watching power either go up or down. You being the tracker. Gets rid of all that overhead and complexitity and coud be worth in some cases where you dont need constant and percise tracking. I have a similar situation with solar tracking as the day goes along. I only need 3 positions, not constant perfect tracking so Im hopig to get an understanding of mppt charge controllers to achieve something like this. Seems like all you'd need is just away to limit the voltage/current, but also not waste it as heat and you should be good for setting up maximum juice for your system. An automated circuit would be ideal, but for educations sake i think a simpler circuit showing the essence of the mppt idea by doing it manualy would be helpful.

phenomenal video, great narration and animations. thanks much

There is a new method for making monocrystalline solar cell material that doesn't involve cylindrical ingots or ribbons. It's explained here in this (very short) tutorial: kzbin.info/www/bejne/e4u0pX2LZa6Vb7M Thanks to this process, it is no longer possible to tell monocrystalline solar panels by the little white diamond shapes at the cell interstices. Those diamonds were the backsheet showing through the cell corners, which were the original cylinder edges. For that reason and for the emergence of the PERC process, which improves efficiency in mono-si cells but not so much in poly-si cells, poly-si is pretty much over as of 2023.

Excellent video. I enjoyed the depth and detailed information format

Excellent, super clear!!!!

Nice

Hats off to you sir, best MPPT explanation on youtube. Really appreciate the content of this video, helped me tons.

can we connect two mppt solar charger controllers to the same solar array ? This is because i have one mppt that works on grid when i have the grid power and then I have another mppt which charges my battery with solar array when there is no grid .

It's not unique to PV. Any energy source has a trade off situation that results in an optimum compromise that varies depending on source and load conditions. Consider bicycle gears... These are selected to optimise the trade off between torque and revs so that the cyclist can produce the most power in the specific riding conditions and his dynamic strength.

thanks for your great efforts. can you please write the name of a useful book containing all this information

The slope of I-V curve at Voc is far from Rseries of cell. That slope is a parallel combination of diode conduction and actual Rs of PV cell. Slope of Isc closer matches Rshunt when defects dominate Rshunt. Both silicon bulk Rseries and bulk silicon Rshunt are affected by illumination level on cell. These resistances increase at low illumination. For shunt this is good at low illumination levels but cell is often dominated by defect shunts. For series resistance this is bad as series resistance increases at low illumination level and dominates over the metal current collection series resistance.

1:59 ❤❤❤❤ thank you sir you gave me us what we needed

4:58 cool

Thanks for your excellence information, Sir.

E =/= qV

So much goes into making a chip no wonder people who make electronics are so creepy when you have their hardware in products you're using right now

doe dat maar

Great Job.

Please give ans .it is important for my research

Sir can we connect together pure silicon rode with silicon steel alloy or p_n_doped silicon using bolting

This is an excellent sleep aid. Also very informative.

I owe my Master's Degree to these videos

Wow!

What a powerful lecture! Thank you, Prof.

What's the k constant, exactly?

This channel has good power info! That silicon is made using geothermal 0 cost silicon factory heating.

Most useful video so far. Thanks!
