Advancement in microelectronics technology enables autonomous edge computing platforms the size of a dust mote. In article number 2004573, Ning Li and co‐workers show that dust‐sized photovoltaic cells on a Si substrate can be integrated using a wafer‐level‐packaging process with other chiplets to achieve high efficiency and high power density. This advancement unlocks the potential of large‐scale manufacturing of these compact integrated systems with high performance and low cost.
