  • Patent number: 10504660
    Abstract: Disclosed is a method for adsorbing a dye for a dye-sensitized solar cell. The method includes: coating a paste including metal oxide nanoparticles on the upper surface of a titanium oxide thin film and calcining the coated paste to form a porous film; adding an additive to a sensitizing dye solution to promote the adsorption of the dye; and dipping the porous film in the sensitizing dye solution to adsorb the sensitizing dye onto the surface of the porous film. The sensitizing dye solution is a dispersion of the sensitizing dye in an organic solvent. Also disclosed are a working electrode prepared using the sensitizing dye solution and a dye-sensitized solar cell including the working electrode. The addition of the additive shortens the time of dye adsorption. Despite the shortened adsorption time, the dye does not undergo desorption in the long term as well as in the short term, ensuring long-term stability of the solar cell.

  • Patent number: 7141943
    Abstract: A brushless DC (BLDC) motor system and a method of controlling the same are provided. The BLDC motor system comprises a BLDC motor including a rotator and a stator, a plurality of switches, a DC current sensor, a position detector and a controller. The stator has a plurality of coils to which currents having different phase are applied. The switches are driven with switching pulses for switching the currents applied to the coils. The position detector detects a position change of the rotator to thereby generate a counter-electromotive force and the DC current sensor senses currents when the currents are applied from the switches to the coils. Based on a magnitude of the counter electromotive force, the controller generates a compensation voltage in order to control the switches during the commutation interval. Further, a duty ratio of the switching pulse is controlled based on the differences between the currents applied to the coils and a reference current.
