A 12 % Efficient Silicon / PEDOT : PSS Heterojunction Solar Cell Fabricated at < 100 ° C
نویسندگان
چکیده
Solar cells based on a heterojunction between crystalline silicon and the organic polymer PEDOT:PSS were fabricated at temperatures < 100oC by spin-coating. The Si/PEDOT interface blocks electrons in n-type silicon from moving to an anode and functions as a low-temperature alternative to diffused p-n junctions. Reverse recovery measurements were used to show that current in the device is primarily due to holes injected from the anode into the silicon. At AM1.5, Si/PEDOT heterojunction solar cells achieve power conversion efficiency (PCE) of 11.7%, which is among the highest reported values for this class of devices.
