Miniature Solar Cell - BPW34

Description Attachments

The BPW34 is a compact, versatile PiN photodiode that serves a multitude of purposes. It can function as a miniature solar cell, powering small, low-energy projects. Alternatively, it can be used as a sensor to detect light. The cell's sensitivity spans a wide range of light wavelengths (430-1100nm), meaning it can produce power in various settings. It boasts an open circuit voltage of 350mV (900nm, 1mW/cm2 light source) and a short circuit current of 47μA.The BPW34 is not only practical, but also enjoyable to use. For instance, when a 940nm infrared LED is shone on it, the cell generates about 0.5VDC open circuit voltage. When four cells are connected in series, they can power an LED. In a well-lit room with fluorescent lighting, they can produce a small voltage of approximately 250mV.The BPW34's features are impressive. It comes in a leaded package type with a top view form. The radiant sensitive area measures 7.5mm2. The cell offers high photo sensitivity and radiant sensitivity, making it suitable for visible and near-infrared radiation. Furthermore, it has fast response times and an angle of half sensitivity of ± 65°. The dimensions of the cell are 5.4x4.3x3.2 mm and it is lead (Pb)-free and RoHS compliant.The BPW34 photodiode is supported by a comprehensive datasheet and a Solar Joule Bracelet Project guide. These resources provide valuable information and inspiration for users to make the most of this versatile device.
