Thin-film image sensors with pinned photodiode structures, using organic or colloidal quantum dot photodiodes, demonstrate noise performance comparable to silicon-based counterparts. These sensors exhibit low noise, reduced dark current, high capacity, and efficient electron-to-voltage conversion. For instance, an organic absorber-based sensor achieves 54% quantum efficiency at 940 nm with 6.1e– read noise.

How Paios was used

The transient photoresponse, photocurrent linearity and capacitance–voltage measurements were performed using a Paios all-in-one system by Fluxim.
