Abstract: A solar cell panel using a back contact solar cell is disclosed. The solar cell panel includes a front substrate, a back sheet positioned opposite the front substrate, a plurality of solar cells positioned between the front substrate and the back sheet and connected to one another by a plurality of conductive lines electrically connecting two adjacent solar cells, an encapsulant covering the plurality of solar cells, and at least one blocking portion blocking the plurality of conductive lines that is otherwise visible between the solar cells from being visually seen. The at least one blocking portion is positioned between a back surface of the front substrate and the encapsulant.

Abstract: A power converting apparatus and a photovoltaic module are discussed. The power converting apparatus includes a converter including a tapped inductor and a first switch, the converter converting a level of an input direct current (DC) voltage and outputting the level-converted DC voltage, and an inverter including a plurality of switches, the inverter converting the level-converted DC voltage into an alternating current (AC) voltage. The inverter operates separately in a first switching mode where the inverter performs a switching operation at a first frequency for a first period of the converted AC voltage and a second switching mode where the inverter performs a switching operation at a second frequency for a second period of the converted AC voltage, the second frequency being lower than the first frequency.
