"dipping conductive plastic (instead of silicon) into salt solution, room temperature photocatalyst dopants (light activated oxygen analogous with photosynthesis) enhances conductivity), inducing positive (p-doping) or negative (n-doping) charges, electron transfer from dopant to organic semiconductor... solution recovered leaving behind p-doped conductive plastic... p- and n-doping in same reaction, parallel manufacturing (scalable)... thermoelectrics, digital displays, solar cells, LEDs, sensors, implants, energy storage"
