PURPOSE: A handsfree kit for a mobile communication terminal is provided to supply a driving power, using a solar cell, without replacing a specific power line or battery. CONSTITUTION: A light collection board(10) is attached on a dashboard of a car, for collecting solar heat and generating a power. A constant voltage generating unit(20) receives the power from the light collection board(10), and generates a constant voltage. A handsfree kit power unit(30) generates a driving power of a handsfree kit by the constant voltage generated in the constant voltage generating unit(20). A handsfree kit driving unit(40) drives a handsfree function of a mobile phone by the driving power of the handsfree kit power unit(30). A battery charging unit(50) charges the constant voltage generated in the constant voltage generating unit(20) in a battery(60). A switching unit(70) is located between the battery(60) and the handsfree kit power unit(30), for providing the voltage of the battery(60) to the handsfree kit power unit(30).
