The BCS1714B4 from TDK Corporation is an Amorphous Silicon-type Solar Panel that consists of 4 cells. It provides an output voltage of 2.0 V and an output current of 7.8 µA. This REACH-compliant solar panel is based on a thin, lightweight, efficient, and flexible solution with a film substrate that reduces the cost of battery replacement and electrical wiring. It uses fluorescent lamps and LED light sources to deliver high power efficiency, thereby extending its overall lifetime and usage time of rechargeable devices. This panel offers a leakage path for liquids, which results in no equipment damage or environmental pollution. It ensures output stability in both low and dim light and allows the end users to customize the design according to various shapes and applications. This RoHS-compliant is available in a panel-mount package that measures 17 x 14 mm and is ideal for clocks, smart cards, smart locks, electronic device charging, beacons, wireless sensor nodes, IoT terminal power supply, energy harvesting, and wearable applications.
