Embodiment 1

[0077] The photoelectric conversion characteristics of the solar cells of Examples 1 to 2 and Comparative Examples 1 and Comparative Example 1 were measured at the output measuring method of the Silicone Crystant Solar Battery of Silicone Crystals according to JIS C 8913: 1998. In the solar optical simulator (SMO-250PV type) combination is equivalent to the atmospheric mass filter of AM 1.5G, adjusting the secondary standard Si solar cell to 100MW / cm 2 The amount of light is measured, and the test sample of the perovskite solar cell is irradiated with the test sample of the perovskite solar cell, and the source table (KEITHLE INSTRUMENTSINC. System, the 2400 generic source table) is used to measure the IV curve characteristics, and derive the measurement of IV curve characteristics. Short-circuit current (ISC), open circuit voltage (VOC), filler factor (FF), series resistance (RS), and parallel resistance (RSH). Moreover, the short circuit current density (JSC) and photoelectric...

Embodiment 2

[0088] In addition to the average film thickness of the back electrode becomes 80 nm, the elements are fabricated in the same manner as in Example 1. As a result, the value of power generation is 7.9% in 1 SUN, and the maximum output of 200 Krex is 16.3μW / cm. 2 . If the average film thickness of the back side electrode is 100 nm or more, for example, when irradiating 1 SUN-like strong light or 200LX-like weak light, it can be obtained due to strong illuminance of incident light. The maximum output is considered to be preferred.

Abstract

The subject of the invention is to provide an element such as a solace cell, from which a terminal is able to be taken out without separating a backside electrode therefrom when the performance of the element is inspected or the terminal is taken out to the outside from the element. The solution of the present invention is about an element which comprises a substrate (3), transparent electrodes (5a, 5b) that are provided on the substrate (3), photoelectric conversion layers (7, 9, 11) and a backside electrode (13), wherein: the transparent electrodes (5a, 5b) include a first transparent electrode part (5a) and a second transparent electrode part (5b), said parts being spatially separated from each other; the photoelectric conversion layers (7, 9, 11) are formed on the first transparent electrode part (5a); and the backside electrode (13) comprises an electrode main body part (13a) that is present on the photoelectric conversion layer (11), an electrode extraction part (13b) that is in contact with the second transparent electrode part (5b), and a bridge (13c) that connects the electrode main body part (13a) and the electrode extraction part (13b) to each other.

Description

Technical field [0001] The present invention relates to an element such as a solar cell or the like. Background technique [0002] When the terminal is taken out from the element such as solar cell, or when the element performance is checked, the terminal is taken out from the back electrode, and the back electrode is needed to be sandwiched with a clamp electrode, or press the pin electrode. At this time, there is a problem that the back electrode flakes of the metal formed by vapor deposition or the like. [0003] The solar cell consisting of the following configuration is described in Japanese Laid-Open Patent Publication No. 2018-163938: The electrode is sealed on the electrode in the laminate of the electrode, the counter electrode, and the photoelectric conversion layer between these. Covered. [0004] Solar cells have problems with conversion efficiency or output in high temperature and high humidity, as described above, in order to extend the life of the solar cell, there...
