Review: Fragile but good - As other reviews note, these are EXTREMELY fragile. That said, they do what they say on the tin (for the most part). Most of the ones I've tested end up reading in the 0.6v range under intense light, and have a consistent gradient of output as light is applied. They're trivially easy to get dirty - 90% or better isopropyl alcohol seems to do a good job for cleaning, and doesn't degrade the cells.
Review: A great fit for custom solar cell projects - Cells are very small - 2 x 3/4 inches. The entire stack of 100 is an inch thick. Each cell is thinner than a postcard, line them up and you can feel the difference with your finger. The entire thing is about three stacked dominoes, the only things I could think of this small. They come extremely well packed. Lots of bubble wrap around a plastic-wrapped bundle of the cells. Still, delicacy is required in handling them. This is an incredibly thin glass substrate. I'm guessing a few will be broken in testing how to mount them to an adequate base material. They seem very powerful for their size. Under a very bright light the yield was 0.65 volts and 140 mA. The current surprised me. It will be interesting to see the results under sunlight. Getting 100 seems about right. There will be breakage at various steps because they are so delicate and I don't need all 100 for my projects. I like being able to make custom arrays of different voltage and current outputs and the price was awesome. Very pleased with the purchase.

## Questions & Answers

**Q: What is the current rating for these cells?**
A: Ok I bought these a while ago and figured out the Amperage mistake/misspelling, The Seller answered "Average Current is About 0.4A,Power: 0.2w 
Average Voltage: 0.5v".............It's 0.04A, not 0.4A, .............im getting about 30-50 mAh under a bright bulb, Also when building panels, in Series voltage is "all cells combined" But Amperage does not go up the same way, so you can build series/parallel circuits(Sets) In Parallel voltage remains the same when cells combined but amperage goes up each cell(combined )

**Q: How do you connect the solar cells? Mine do not have blue markings and the only way I know which edge is positive and negative is by testing each cell**
A: Hi friend,you need to use the welding strip to connect it ,and the Gray side is the postive , the Blue side is the negative ,so hope it can help you,thanks

**Q: Hello, what is the size (Dimension) of these solar cells, please? I need one that is 3" x 6"**
A: Hi friend,this solar cells size is  3/4”x2” inch,if you want large size,pls check this link:https://www.amazon.com/dp/B07DC4VKBG, hope it can help you,thanks

**Q: What can be applied over or under these cells to make them more rigid and less fragile?**
A: Hi friend,you can use it made the solarpanel diy ,and use the welding strip to connect them,thanks for your questions

### ⭐⭐ hilariously fragile, reject quality
*by A***R on September 12, 2024*

BURN MARKS. these cells do work but they are straight up not meant to be used as components like this. Many of the cells have burn marks and other indications of quality being poor. But lemme not understate how incredibly fragile these things are. A name brand potato chip has more rigidity and flexibility than these things. They literally have the durability of a paint chip or dried snot, basically none. Any slight amount of bending force is likely to damage these. YOU HAVE BEEN WARNED.
