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: Very, Very fragile 1 - Electrically, these are a five-star product, but you might not wind up being to use them. They seem to be an intermediate manufacturing product: scribed from the silicon wafer but not prepared for end use. Extremely thin and brittle. The product description is accurate and to be believed. Ideally, they would be integrated into solar-power manufactured goods - handled robotically and terminated by automated equipment. Prove me wrong by using a manual vacuum tip and your micro-soldering skills. I have done successful cell phone parts-level repair using watchmakers magnifying glasses and dental tools. It is the unsupported silicon wafer structure that is the difficulty. These mini solar cells are a good value if you can use them. Note that the surface and metallization is unprotected: vulnerable to destruction from contamination and moisture as well as mechanical damage. I had some luck glueing them down to G-10 epoxy-glass laminate circuit board material but ultimately had to buy PV solar cells already packaged and terminated. In a word: these are an excellent product but probably not suitable for use by us experimenters and inventors. ## Features - ❶【Please Attention】This solar panel is very thin and light, so it is very fragile. Please be careful when it is used， handle it lightly and buy it carefully. - ❷【Product Parameter】100pcs Polycrystalline Silicon solar panels; Power:0.5V 400mA ;Size : 2"x0.75";Connection way: The blue side connect "-"(negative) , white side connect "+"(positive). In order to ensure enough power, Suggest use solder strip. - ❸【Experience the fun of DIY】Build your DIY powered models/solar toys / solar displays/Solar Powered String Lights. Arbitrarily change the output power and voltage through different connect way in series or in parallel, meet your needs! If you use it by DIY ,testing ... it is very worth, factory price here. - ❹【Widely used and Widely temperature range】Suitable for outdoor activities, emergencies and outdoor work. Power is continuously supplied even on cloudy days. - ❺【High Conversion EffIciency】 Constructed of high-efficiency solar arrays,convert up to 21.5-23.5% of solar power into free energy. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01NCQRCQR | | Amperage Capacity | 400 Milliamps | | Best Sellers Rank | #439,036 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1,482 in Solar Panels | | Brand Name | AOSHIKE | | Connector Type | Micro Usb | | Customer Reviews | 3.7 3.7 out of 5 stars (140) | | Efficiency | High Efficiency | | Global Trade Identification Number | 06922082302053 | | Included Components | 100pcs 0.5V 400mA Micro Mini Solar Cell | | Item Dimensions L x W x H | 2.05"L x 0.75"W x 0.75"H | | Item Weight | 2.39 Ounces | | Manufacturer | AOSHIKE | | Manufacturer Part Number | 4332695008 | | Material Type | Polycrystalline Silicon | | Maximum Power | 0.2 Watts | | Maximum Voltage | 50 Volts (DC) | | Model Number | 4332695008 | ## Product Details - **Brand:** AOSHIKE - **Efficiency:** High Efficiency - **Item Weight:** 2.39 Ounces - **Material:** Polycrystalline Silicon - **Product Dimensions:** 2.05"L x 0.75"W x 0.75"H ## Images ![100pcs 0.5V 400mA Micro Mini Solar Cell for Solar Panels 52mmx 19mm/2‘’x0.75” Polycrystalline Silicon Photovoltaic Solar Cells Sun Power for DIY Cell Phone Charger - Image 1](https://m.media-amazon.com/images/I/61Xu-NS4zTL.jpg) ![100pcs 0.5V 400mA Micro Mini Solar Cell for Solar Panels 52mmx 19mm/2‘’x0.75” Polycrystalline Silicon Photovoltaic Solar Cells Sun Power for DIY Cell Phone Charger - Image 2](https://m.media-amazon.com/images/I/61MepR3uAtL.jpg) ![100pcs 0.5V 400mA Micro Mini Solar Cell for Solar Panels 52mmx 19mm/2‘’x0.75” Polycrystalline Silicon Photovoltaic Solar Cells Sun Power for DIY Cell Phone Charger - Image 3](https://m.media-amazon.com/images/I/717QPmDvOGL.jpg) ![100pcs 0.5V 400mA Micro Mini Solar Cell for Solar Panels 52mmx 19mm/2‘’x0.75” Polycrystalline Silicon Photovoltaic Solar Cells Sun Power for DIY Cell Phone Charger - Image 4](https://m.media-amazon.com/images/I/61nfwTlwNzL.jpg) ![100pcs 0.5V 400mA Micro Mini Solar Cell for Solar Panels 52mmx 19mm/2‘’x0.75” Polycrystalline Silicon Photovoltaic Solar Cells Sun Power for DIY Cell Phone Charger - Image 5](https://m.media-amazon.com/images/I/61Zl-MWmRSL.jpg) ## 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fragile but good *by O***H on November 17, 2025* As other reviews note, these are EXTREMELY fragile.
