They successfully produced a thin-layer structure with a practical size of 101.8 cm 2 total area, and reached an open circuit voltage value of 0.75 with a fill factor of 0.832. The next record came from Panasonic with an efficiency of 25.6% HIT solar cell in 2014 under 1-sun illumination .
HIT solar cells have a symmetric structure with a thin mono crystalline silicon wafer coated by ultra-thin amorphous silicon (a-Si:H) layers on both front and back surfaces, Fig. 8. The aim is mainly the passivation of the interface to decrease the recombination rate of the e-h pairs at the interface due mainly to dangling bonds.
