Abstract :
The use of low temperature ALD grown ZnO as emitter and TCO coating for a-Si PIN solar cells is studied. Several cells are fabricated with 30nm ALD ZnO on top. The grown ALD ZnO without any additional TCO resulted in photovoltaic behavior. This confirms that the ZnO is acting as both an n-type semiconductor and TCO layer simultaneously. The measured open circuit voltage Voc = 0.25V and short-circuit current Jsc =1.63 mA/cm2 is achieved. In addition the EQE and IQE are measured and compared.
