Abstract
A thin film transistor structure including a substrate, a gate, an oxide semiconductor layer, a gate insulation layer, a source, a drain, a silicon-containing light absorption layer and an insulation layer is provided. The gate insulation layer is disposed between the oxide semiconductor layer and the gate. The oxide semiconductor layer and the gate are stacked in a thickness direction. The source and the drain contact the oxide semiconductor layer. A portion of the oxide semiconductor layer without contacting the source and the drain defines a channel region located between the source and the drain. The oxide semiconductor layer is located between the substrate and the silicon-containing light absorption layer. The silicon-containing light absorption layer has a band gap smaller than 2.5 eV. The insulation layer is disposed between the oxide semiconductor layer and the silicon-containing light absorption layer, and in contact with the silicon-containing light absorption layer.
