    Abstract: A method for manufacturing a two terminal or three terminal tandem solar cell comprising a silicon-based bottom solar cell (2) and a thin- film top solar cell (11); the method comprising: providing a silicon substrate (3) with a front surface and a rear surface, carrying out a sequence of steps comprising: creating on the front surface a carrier extracting layer stack (16) comprising at least a carrier extracting layer (8) formed on or in the front surface of the substrate, creating on the rear surface a passivating coating layer comprising deposition of a first AIOx layer (9), creating sacrificial layer stack comprising a second AIOx layer (6) on the carrier extracting layer stack on the front surface; creating metal-based electrical contacts (7) on the rear surface, including an annealing step; removing the sacrificial layer stack from the carrier extracting layer stack, and creating the thin film top solar cell on the carrier extracting layer stack.

    Abstract: An intermediate reflector layer in a thin film tandem solar cell is manufactured in that there is deposited a layer by PEDVD in a process atmosphere which is fed by a gas mixture comprising H2, SiH4, a dopant gas and CO2. The flow ratio of H2 to SiH4 is selected to be between 100 and 400 and the CO2 to SiH4 flux ratio is selected as high as possible, thereby maintaining electric conductivity of the layer.

    Abstract translation: 制造薄膜串联太阳能电池中的中间反射层，其中在由包含H 2，SiH 4，掺杂气体和CO 2的气体混合物供给的处理气氛中通过PEDVD沉积层。 选择H 2与SiH 4的流量比在100和400之间，并且选择尽可能高的CO 2与SiH 4通量比，从而保持该层的导电性。
