Miniature Solar Cell - BPW34

Model No: SOL-00001

TK. 170.55

Availability: In stock


Category: Solar

Supplier: SparkFun, USA

Product package contains 1 solar cell.


The BPW34 is a tiny, general purpose PiN photodiode. This photodiode has a ton of uses, one of which is to use it is a mini solar cell to power your project. The cell is sensitive to a wide range of light wavelengths (430-1100nm), so it should produce power in a number of different settings. The rated open circuit voltage is 350mV (900nm, 1mW/cm2 light source), and short circuit current is 47μA.

These are fun (of course)! We shined a 940nm infrared LED on one of them and it produced about 0.5VDC open circuit voltage. Stringing four together in series, we were able to turn an LED on with them. They’ll also produce a small voltage, ~250mV, in a brightly, fluorescent-lit room.

Q: How is its output mA? Questioned by SHABABANAM, 20-Jun-2016

Short Circuit Current = 50 Micro-Ampere. Answered by FAHIM_REAZA, 21-Jun-2016 09:33 AM

Q: jodi 2 ta series e lagai then mobile e charge dewar jnno j power bank use kori oita charge dewa jabe? gele kivabe dibo, n na gele reasn ta ki?? janaben Questioned by rumon2071, 06-Aug-2016

No. You can't use it to make a charge for your power bank. Because power bank uses 5v to charge and if you make a series connection with two "Miniature Solar Cell - CPC1822", that make a 8V output voltage and may damage the power bank. Answered by FAHIM_REAZA, 09-Aug-2016 10:07 AM

Do you have any PCB to mount this "Miniature Solar Cell - CPC1822" ? Answered by FarhadSyed, 11-Feb-2017 02:46 AM

PCB must be done by user. Answered by A.R, 11-Feb-2017 10:18 AM

Q: When this product will be available? Questioned by azimuddin, 18-Oct-2016

Within next week hopefully. Answered by A.R, 19-Oct-2016 16:21 PM

Q: I want to create a short circuit across the solar cell by connecting an ammeter across it. How can I do it without using a PCB? Questioned by absur_siam, 28-Apr-2018

This is smd package. So, PCB must be done. Answered by A.R, 28-Apr-2018 10:38 AM

Can't I touch the ammeter's cathode and anode with the pins of the cells and measure the current? Answered by absur_siam, 28-Apr-2018 11:47 AM

This is breadboard friendly. You can place it on breadboard and connect one male to male jumper in parallel with each leg. Then you can touch the ammeter probes with the two ends of the jumpers. Answered by A.R, 30-Apr-2018 09:55 AM
