Abstract :
The heterojunction solar cell structure consists of thin doped amorphous SiC layer and crystalline n-type silicon. Dark and light current-voltage (I–V) measurements were performed in order to obtained basic electric and PV parameters of prepared solar cell structures. Biased complex impedance spectra of Al/a-SiC/c-Si(n)/Al heterojunction in the dark are reported and analyzed. AC equivalent circuit was obtained by fitting of impedance dependences and its electronic components were used to describe the electronic transport properties of prepared structures.
