There are growing opportunities and demands for image sensors that produce higher-resolution images, even in low-light conditions. Increasing the light input areas through 3D architecture within same pixel size can be an effective solution to address this issue. Organic photodiodes (OPDs) possess wavelength selectivity allow advancements regard. Here, we report on novel push-pull D-π-A dyes specially designed Gaussian-shaped, narrow-band absorption high photoelectric conversion. These p-type organic work both as a color filter source of photocurrents with linear fast responses, sensitivity, excellent stability, when combined C60 form bulk heterojunctions (BHJs). The effectiveness OPD composed active was demonstrated by obtaining full-color using camera contained organic/Si hybrid complementary metal-oxide-semiconductor (CMOS) sensor.
