“…For inverted OPDs, the EBL is deposited on the organic layer and top electrode, and it is required that the preparation of this interface layer does not destructively affect the active layer. Wagner et al realized semi-transparent inverted organic detectors with a 50 nm PEDOT:PSS layer, which used solution-based fabrication and exhibited an overall transmittance of about 20% in the visible range of the electromagnetic spectrum [129].…”

As a promising candidate for next-generation photodetectors, organic photodetectors (OPDs) have gained increasing interest as they offer cost-effective fabrication methods using solution processes and a tunable spectral response range, making them particularly attractive for large area image sensors on lightweight flexible substrates. Carrier blocking layers engineering is very important to the high performance of OPDs that can select a certain charge carriers (holes or electrons) to be collected and suppress another carrier. Carrier blocking layers of OPDs play a critical role in reducing dark current, boosting their efficiency and long-time stability. This Review summarizes various materials for carrier blocking layers and some of the latest progress in OPDs. This provides the reader with guidelines to improve the OPD performance via carrier blocking layers engineering.

Organic photodiodes (OPDs) have recently garnered attention as a competitive alternative to their inorganic counterparts, given their inherent advantages in solution processability, mechanical flexibility, and cost‐effective manufacturing. In this work, a novel method for fabricating high‐performance semitransparent color OPDs by integrating Fabry–Perot (FP) interferometer‐based color‐filtering electrodes and solution‐processed distributed Bragg reflectors (sDBRs) is introduced. The FP electrode provides color control by modulating the metal oxide layer thickness, irrespective of the photoactive layer's color. To overcome limitations related to light absorption and device transparency, this work employs a sDBR as a selective window reflector, allowing the OPD to retain its color while preserving semitransparency. The experimental findings demonstrate the successful integration of these components, resulting in semitransparent red, green, and blue (RGB) OPDs exhibiting significantly improved detectivity. The fabricated RGB‐OPDs achieve detectivity values of 4.07, 3.49, and 4.22 × 1010 cm Hz1/2 W−1 for red, green, and blue, respectively. This research highlights the efficacy of FP and sDBR color filters in realizing high‐performance color sensors and offer novel opportunities for semitransparent OPD integration with other optoelectronic devices.
