An exemplary method of manufacturing a light-absorbing layer and a method of manufacturing a semiconductor device including the same light-absorbing layer are provided. The exemplary method includes: forming a nanoparticles film by applying a semiconductor nanoparticles solution on a substrate; thermally treating the nanoparticles film at least one time to cause adhesion among the nanoparticles; and forming a light-absorbing layer by applying a light-absorbing solution on the nanoparticles film.

An active region or channel for printed, organic or plastic electronics or polymer semiconductors, such as organic field-effect transistors (OFETs), is obtained by using an enhanced inkjet drop-cast printing technique. A two-liquid system is employed to achieve the direct growth of well-oriented organic crystals at the active region of channel. High-performance electrical properties exhibiting high carrier mobility and low threshold voltage are obtained due to the proper orientation of molecules in the grown crystal in a highest mobility direction, due to the absence of grain boundaries, and due to low trap densities. The hydrophobic-hydrophilic interactions between the liquids utilized, which results in the fabrication of low-cost and mass-producible printable electronic devices for applications in flexible displays, electronic signages, photovoltaic panels, membrane keyboards, radio frequency identification tags (RFIDs), electronic sensors, and integrated electronic circuits.
