Compared to traditional solar panels, ETFE solar panels with IBC solar cells produce more energy for the same sized solar panel than traditional one. The structure of ETFE solar panel is ETFE film / EVA / IBC solar cells / EVA / PCB. Instead of front contact energy conversion, IBC solar cell has back contact energy conversion, which allows for the entire front of the cell to absorb sunlight, without any shading from the metal ribbons, making it more efficient. Meanwhile it has a thick copper foundation; thus the IBC solar cell is more durable and doesn’t break easily. ETFE solar panels are produced through STM automatic placement technology, so they can be more flexibly customized into various small-sized solar panel designs. ETFE solar panels are widely used in wireless sensors, IoT devices, crafts, toys, LED lights and other small electronic devices.
