cm-3<span style="color:#1C1D1E;font-family:" font-size:16px;white-space:normal;background-color:#ffffff;"="">), which are comparable to the corresponding bulk crystals. The unique embedded structure of PSCs within the microchannels allows the construction of a high‐integration image sensor. This work paves the way toward high‐throughput growth of PSCs for integrated optoelectronic devices.
