In 2014, three companies broke the record of 25.6% for a silicon solar cell. Panasonic''s was the most efficient. The company moved the front contacts to the rear of the panel, eliminating shaded areas. In addition they applied thin silicon films to the (high quality silicon) wafer''s front and back to eliminate defects at or near the wafer surface. [60] In 2015, a 4-junction
In terms of processing, solar cells based on n-type silicon show a slightly higher complexity and higher manufacturing cost, as both phosphorus for the BSF and boron for the emitter (the region of the wafer showing opposite doping from the bulk) 48 have to be diffused, and because both front and rear metal layers require silver-based pastes.
The first step in producing silicon suitable for solar cells is the conversion of high-purity silica sand to silicon via the reaction SiO 2 + 2 C → Si + 2 CO, which takes place in a furnace at temperatures above 1900°C, the carbon being supplied usually in the form of coke and the mixture kept rich in SiO 2 to help suppress formation of SiC.
