施加到基板上的涂层，太阳能电池以及将涂层施加到基板上的方法

Coating which is applied to substrate, a solar cell, and method for applying the coating to the substrate
Abstract:
The invention relates to a coating which has been applied to a substrate, comprising at least a first film and a second film which have been applied on top of each other and each comprise a transparent conducting oxide and an electron donor, wherein the second film comprises relatively at least 10 percent less electron donor than the first film. The invention also relates to a solar cell comprising a coating according to the invention. The invention further relates to a method for applying the coating according to the invention to a substrate, wherein at least a first and a second mixture which each comprise one or more precursors for a transparent conducting oxide and an electron donor are applied to the substrate, wherein the second mixture is composed such that relatively at least 10 percent less electron donor is incorporated in the film compared with the film deposited by the first mixture.
Abstract(Chinese):

本发明涉及已经施加到基底上的涂层，该涂层包括至少第一膜和第二膜，其已被施加在彼此的顶部上，并且每个包括透明导电氧化物和电子给体，其中第二膜包括 比第一膜少至少10％的电子给体。 本发明还涉及包含根据本发明的涂层的太阳能电池。 本发明还涉及将根据本发明的涂层施用于基底的方法，其中至少第一和第二混合物各自包含用于透明导电氧化物和电子给体的一种或多种前体， 其中所述第二混合物的组成使得与所述第一混合物沉积的膜相比，在所述膜中相对少于10％的电子给体被引入。
