  • Patent number: 9124116
    Abstract: A charge relay enhancer used in relaying a charge produced in a solar cell to a charger, and a solar cell system including the charge relay enhancer. The charge relay enhancer includes: a charge induction and pumping device inducing a charge by using a power voltage from among two power voltages of different polarities selected in response to a control signal, and pumping the induced charge; and a charge pathway selecting device relaying the charge input to an input terminal via two input/output terminals, to the charge induction and pumping device, receiving the charge pumped by the charge induction and pumping device via the two input/output terminals, and outputting the charge to an output terminal. Accordingly, as charges produced in a solar cell may be relayed to a charging device as much as possible, efficiency of relaying charges produced in the solar cell to the charging device may be maximized.

  • Patent number: 8608976
    Abstract: A photo alignment material includes a photo alignment polymer and an organic solvent. The photo alignment polymer is prepared by polymerizing a diamine monomer including at least two photo reactive parts represented by the following Chemical Formula 1. In Chemical Formula 1, R1 represents —(CH2)n—, —O(CH2)n— or R2, R3 and R4 each independently represent —H, —O(CH2)m—1—CH3 or and n and m independently represent an integer of from 1 to 8.
