23, 1996 1. Clear glass 5,538,903 2. Electrical Insulation N-type Cd’s layer = Negative . In Electrode Positive Terminal An current collecting carbon electrode layer silver & Indium mixed to a printable past. Ag & In P - Type CdTe Layer Double or triple print #2, to do this you print the first layer, let dry and then print the 2nd layer = 60 um thickness. #3 layer print only one layer using the same screen printing screen. S. Patent 5,538,903 Jul. 23, 1996 METHOD OF MANUFACTURING SOLAR CELL BACKGROUND OF THE INVENTION 1.
55 In the manufacturing of the compound semiconductor solar cell by the coating and firing method, it is important that each of the n-type compound semiconductor layer p-type compound semiconductor layer, and electrode layer have uniform thickness, a smooth surface. and no pin holes! Especially if the n-type CdS semiconductor layer formed directly on the substrate is uniform, smooth and non- porus, the adherence of the lto the substrate is improved, resulting in an increase of the light transmittance.
To obtain the above object, a method of manufacturing a solar cell according to the present invention comprises thsteps of forming a layer of an n-type compound semiconductor, a layer of a p-type compound semiconductor, and an electrode layer on a glass substrate, wherein at least one of said steps of forming a layer of compound semiconductor comprises preparing a paste by mixing a semiconductor raw material and a viscous agent, applying said paste to said substrate, drying said paste to harden it and firing said dried paste, and vibrating said substrate during or after the application of the paste.
