Solar cell and method for manufacturing same

A method for manufacturing a solar cell, comprising:

• providing a substrate comprising a plate-like base having heat dissipation properties, and a first conductive line and a second conductive line disposed and electrically isolated from each other on the base;
• providing a plurality of multi-junction solar cell units each comprising a lower electrode, a cell stack comprising a bottom cell layer disposed on an upper surface of the lower electrode and a top cell layer disposed on an upper surface of the bottom cell layer, a transparent electrode disposed on an upper surface of the top cell layer, and a conductor connecting the transparent electrode to the second conductive line;
• providing a glass plate;
• bonding upper surfaces of the transparent electrodes of the plurality of solar cell units to one face of the glass plate to fix the plurality of multi-junction solar cell units to the glass plate;
• attaching the plurality of multi-junction solar cell units to the substrate so that in each multi-junction solar cell unit, the lower electrode is electrically connected to the first conductive line and the conductor is electrically connected to the second conductive line;
• providing a sheet-like condenser lens having a plurality of focal points;
• and
• bonding the condenser lens to the other face of the glass plate,
• wherein the condenser lens has a recess at a part of an adhesive surface to the glass plate other than a light transmitting portion.
