Embodiment 1

[0286]

[0287] On a glass substrate serving as a first substrate, an indium-doped tin (ITO) film and a niobium-doped tin oxide (NTO) film were sequentially deposited as a first electrode by sputtering. Subsequently, a dense layer formed of titanium oxide serving as a hole blocking layer was formed by reactive sputtering. Subsequently, a part of the ITO / NTO and the hole blocking layer formed on the substrate was etched by laser processing so that the interval between adjacent photoelectric conversion elements was 10 micrometers.

[0288] Subsequently, 3 g of titanium oxide (ST-21, available from ISHIHARA SANGYOKAISHA, LTD.), 0.2 g of acetylacetone, and 0.3 g of surfactant (polyoxyethylene octylphenyl ether, (obtained from Wako Pure Chemical Corporation) together with 5.5 g of water and 1.0 g of ethanol for bead milling for 12 hours to obtain a titanium oxide dispersion. To the obtained titanium oxide dispersion, add 1.2 g polyethylene glycol (#20,000, obtained from Wako Pur...

Embodiment 2

[0296] Voc1 , Pmax1 , Voc2 , Pmax2 , and retention were obtained in the same manner as in Example 1 except that the distance between the first electrodes of adjacent photoelectric conversion elements and between the hole blocking layers was changed to 200 μm. The structure of the modules is presented in Table 1. The results are presented in Table 2.

Abstract

Provided is a solar cell module including photoelectric conversion elements, wherein each of the photoelectric conversion elements includes a first substrate, and a first electrode, a hole blocking layer, an electron transport layer, a hole transport layer, a second electrode, and a second substrate on the first substrate, and a sealing member between the first substrate and the second substrate,and wherein, within at least two of the photoelectric conversion elements adjacent to each other, the hole-blocking layers are not extended to each other but the hole transport layers are in a state of a continuous layer where the hole transport layers are extended to each other.

Description

technical field [0001] The present disclosure relates to solar cell modules. Background technique [0002] In recent years, solar cells have become increasingly important as an alternative energy source to fossil fuels and as a measure against global warming. In addition, in recent years, solar cells capable of efficiently generating electricity with light of low illuminance and used indoors have attracted much attention. In particular, the latter solar cells are expected to be used in a wide range of applications as self-sustaining power sources that do not require battery replacement or power wiring. [0003] As photoelectric conversion elements for indoor use, amorphous silicon solar cells and dye-sensitized solar cells are known. Among them, the dye-sensitized solar cell is advantageous in terms of cost reduction because the dye-sensitized solar cell can be produced using a printing method known in the art. Generally, the dye-sensitized solar cell has a problem of eva...
