In this recently published communication, our researchers report a novel hybrid energy harvesting-storage architecture consisting of anodic amorphous MoOx (a-MoOx) pseudocapacitive electrode monolithically integrated on the rear Al electrode of an industrial screen-printed Si soalr cell.  The c-Si solar cell can efficiently generate power, and the MoOx pseudocapacitor can mitigate the instability of solar energy by providing a buffer when the sunlight is insufficient. An average capacitance of 34 mF cm−2, energy density of 3.6 mJ cm−2, and capacity of 18 mC cm−2 were achieved from the light charge–galvanostatic discharge tests. This energy storage represents a significant increase over previous hybrid devices based on c-Si solar cells.
