Method of production of CIS-based thin film solar cell
A method of production of a CIS-based thin film solar cell comprises the steps of forming an alkali control layer on a high strain point glass substrate, forming a back surface electrode layer on the alkali control layer, forming a CIS-based light absorption layer on the back surface electrode layer, and forming an n-type transparent conductive film on the CIS-based light absorption layer, wherein the alkali control layer is formed to a thickness which allows heat diffusion of the alkali metal which is contained in the high strain point glass substrate to the CIS-based light absorption layer and, furthermore, the CIS-based light absorption layer has an alkali metal added to it from the outside in addition to heat diffusion from the high strain point glass substrate.
The solar cell module having a preferable edge space that prevents characteristics of a solar cell such as conversion efficiency from being deteriorated without making processes complicated is provided. In a method for manufacturing a solar cell module including a substrate glass, a first layer formed on the substrate glass and a second layer formed on the first layer, the method includes a step of forming a first edge space having a first width by removing the first layer and the second layer by the first width from an end part of the glass substrate and a step of forming a second edge space by removing only the second layer by a second width from the end part of the glass substrate, and the width of the second edge space is larger than the width of the first edge space.

In order to manufacture a CIS-based thin film solar cell that can achieve high photoelectric conversion efficiency by adding an alkali element to a light absorbing layer easily and with good controllability, a backside electrode layer (2) is formed on a substrate (1). Then, a p-type CIS-based light absorbing layer (3) is formed on backside electrode layer (2), and then an n-type transparent and electroconductive film (5) is formed on this p-type CIS-based light absorbing layer (3). At this time, the backside electrode layer (2) is constituted by forming a first electrode layer (21) using a backside electrode material in which an alkali metal is mixed and, then forming a second electrode layer (22) using the backside electrode material that does not substantially contain the alkali metal.

Method of testing durability of CIS based thin-film solar cell module
2, and the module is continuously irradiated with the weak light throughout the test period under the same temperature, humidity, and storage period conditions as those in the conventional conditions for the test (1,000-hour storage in the dark at a temperature of 85° C. and a relative humidity of 85%). Thus, the property of the module 2′ that the module 2′ does not show considerable deterioration even after storage in an open state for 1,000 hours can be correctly evaluated.
