Silicon heterojunction solar cells with microcrystalline emitter

用微晶发射器的硅异质结太阳能电池

AbstractMicrocrystalline n-type emitters, that, compared to a-Si:H ones, ensure better electronic properties and better transparency in thevisible, were used to fabricate heterojunction solar cells on crystalline silicon. The substrate surface was passivated by the depositionof a very thin intrinsic a-Si:H buffer layer. The microcrystalline n-type emitters were deposited by radio-frequency (rf) plasmaenhanced chemical vapor deposition, using a high hydrogen diluted gas mixture. The simulation of optical spectra of n/i doublelayers on c-Si gives a preliminary evidence that the continuity of the intrinsic a-Si:H buffer layer is preserved after the rf deposition.The photovoltaic devices incorporating microcrystalline emitters exhibit a remarkable increase of short circuit current (Jsc) andefficiency (a factor 1.24 and 1.38 respectively) compared to the case of a-Si:H emitters. Noticeable improvements are observed if thestructure is applied to textured substrates.
