Objective
Solar cells made from hydrogenated amorphous silicon (a-Si:H) with pin structure are well established for powering such consumer devices as watches, pocket calculators and small battery chargers. However, the application of a-Si:H solar modules in the power market is mainly impeded by the light-induced degradation during operation (Staebler-Wronski-Effect). The use of thin i-layers reduces this degradation, but also the amount of absorbed light. The objective of this project is to develop a new type of stocked solar cells having the structure pir/TCO/Nip.
In stacked solar cells, single junctions with thin i-layers are combined In stacked solar cells, single junctions with thin i-layers are combined and a sufficiently large absorption length is obtained. Conventionally, and a sufficiently large absorption length is obtained.

In our This represents a stringent condition on the two individual i-layer thicknesses which is even more difficult to satisfy in a large area project we want to develop a new type of stacked solar cells having the structure pin/TCO/nip (TCO=transparent conductive oxide). In this deposition.
In our project we want to develop a new type of stacked solar cells having structure the two subcells (pin and nip) are electrically connected in parallel and the two photocurrents simply add up independently of the the structure pin/TCO/nip (TCO=transparent conductive oxide). In this structure the two subcells (pin and nip) are electrically i-layer thicknesses. The two n-layers are directly combined via the TCO-layer in between and the two p-layers will be connected via the front-connected in parallel and the two photocurrents simply add up independently of the i-layer thicknesses.
