Understanding Solar Cell Efficiency and Production: What You Need to Know

AI Thread Summary
A recent advancement in solar technology has led to the development of a 40% efficient solar cell, which indicates its ability to convert 40% of sunlight into usable electricity. Efficiency is calculated based on the ratio of electrical output to the solar energy input under standard testing conditions. The terms "monocrystalline" and "polycrystalline" refer to the types of silicon used in solar cells, with monocrystalline cells generally offering higher efficiency and space efficiency compared to polycrystalline cells. The discussion highlights the importance of citing sources for accurate information, as terminology can vary in meaning. Understanding these concepts can enhance knowledge about solar energy technology.

Hey,
I recently read that they made a 40% efficient solar cell... what does this actually mean? How do they calculate this efficiency... and how much power do these cells actually produce? and what's with the mono and poly crystalline titles that they get? what does that mean??

Any info would be helpfull... :smile:

Next time, when you "read" something interesting and wish to discuss it on here, please cite the EXACT reference. If not, words like "mono crystalline" and "poly crystalline" can have a multitude of meanings!

Zz.
 
yeah... I feel kinda stupid... should have probably tried googling first... OH well...
thx for clarifying the doubts though... :)
