J. Huang and co-workers report a low-noise, highsensitivity, fullerene-based organic photo detector with a wide dynamic range. The enhanced dynamic range depicted here is achieved via an inserted cross-linkable buffer layer. The device described on page 289 shows an excellent linear response from indoor light intensity to 12 pW m−2, corresponding to a linear dynamic range of 90 dB. This is among the highest reported for any organic photodetector, and larger than those of inorganic photodetectors such as GaN and InGaAs.
