SnO₂-Si Heterojunction 태양전지의 전기적 특성에 대한 연구
신기택(Ki Tack Shin) 산업기술교육훈련학회 2013 산업기술연구논문지 (JITR) Vol.18 No.4
Semiconducting SnO₂ film has been deposited on the surface of Si single crystal by the C.V.D method, and the Electrical properties have been I on investigated SnO₂-Si n-n heterojunction. The I-V characteristics SnO₂-Si n-n heterojunction showed a good rectification. In this paper, through the window of the reactor color interference control the thickness of the changes slowly enough to spray Chemical vapor deposition of solar cells made using the electrical properties of materials will be investigated.

In this paper, a direct conversion from single-phase to three-phase alternating current using thyristor switching device is proposed, and this system is proposed to remove several defects inherent in the device feeding from a single phase power, when the converter is used to an induction motor drive this system could achieve an excellent characteristics such as high starting torque and low starting current. The smooth output voltage wave form and sinusoidal input current could be obtained by replacing the conventional rectifier circuit with the convertor.

This paper presents the 2nd excitation control of the wound-rotor induction motor with Fly-wheel. In the wound-rotor induction motor, the primary power is controlled by AC excitation which used the secondary power conversion. Based on theory, this paper describes the dynamic response analysis of the wound-rotor induction motor with Fly-wheel and Simulation using MA TLAB is performed to verify the proposed control method.

A phase winding of RSM is excited and measured the excited winding inductance, mutual inductance, L_ d and L_ q is calculated from the measurement result. Tow rotors are manufactured for this paper, measured their inductance and compared the calculated equation with the conventional equation. This paper confirmed the effectiveness of the proposed method.<br/> <br/>
