Solar cells inspire Li-ion batteries

Solar energy is at the forefront of the global shift toward producing sustainable energy sources and addressing energy poverty. However, the intermittent nature of solar energy limits its use for applications such as IoT devices, live remote sensing and an off-grid power supply. Conventionally the batteries are powered by solar cells to store the energy for later use. However, the physical combination of these two technologies requires separate packaging of both systems, is cumbersome to install, and requires more electrodes, which increases the cost and ohmic losses in the device.
