Bifacial crystalline silicon solar panel with reflector

A bifacial solar cell (110) comprising:

• (a) an n-type semiconductor layer (32);
• (b) a plurality of first metal conductivity lines (24) coupled to a first side of the n-type semiconductor layer (32);
• wherein at least some of the first metal conductivity lines (24) are in electrical communication with the n-type semiconductor layer (32);
• (c) a p-type crystalline silicon layer (36) coupled to a second side of the n-type semiconductor layer (32), wherein a thickness of the p-type crystalline silicon layer (36) is at least 20 micrometers;
• (d) a barrier layer (40) coupled to the p-type crystalline silicon layer (36), and located opposite the n-type semiconductor layer (32);
• wherein the barrier layer (40) comprises at least one of:
• oxides of vanadium, oxides of molybdenum, nitrides of aluminum, tungsten nickel oxide, and boron doped diamond;
• and
• wherein the bifacial solar cell (110) is absent an additional silicon-based layer between the n-type semiconductor layer (32) and the barrier layer (40);
• (e) a transparent conductive layer (44) coupled to the barrier layer (40), and located opposite the p-type crystalline silicon layer (36);
• (f) a plurality of second metal conductivity lines (48) coupled to the transparent conductive layer (44), and located opposite the barrier layer (40);
• wherein at least some of the second metal conductivity lines (48) are in electrical communication with the transparent conductive layer (44).
