Abstract

PURPOSE:To improve cell efficiency remarkably by a simple structure, by inputting scattered light from the side of a substrate to a lowermost cell layer. CONSTITUTION:A substrate 101 is constituted by a transparent material. Light can be inputted from the side of the back surface of the substrate through a part of the substrate. For example, a transparent electrode 17 is formed so as to cover a metal electrode 16, which is formed on the substrate 101 in a grid shape. A first PIN cell layers 2, 3 and 4 form a cell, whose main component is a-SiGe. In this structure, scattered light can be inputted from the side of the back surface together with incident light form the upper surface of a tandem structured cell. The light, which is inputted from the back surface side, reaches the P-N interface, and a high resistance region is reduced. Therefore, the sensitivity of the long wavelength light of the cell (the first layer) for the long wavelength light is improved, and the high-performance cell is obtained.

Generate hole pairs to generate photocurrent. The light components absorbed within each layer are shown in Figure 4 as a wavelength sensitivity curve (
The sensitivity region gradually shifts in the wavelength band, as indicated by the spectral sensitivity (spectral sensitivity). Since three layers of solar cells with shifted sensitivity regions are stacked in this manner, high sensitivity can be maintained over a wide range of wavelengths as a whole, and a highly efficient photoelectric conversion device can be obtained. In order to obtain high efficiency here, the first step is to obtain high efficiency.
The photocurrents generated in the second and third layers must be equal.

In order to overcome this drawback, attempts have been made to increase the photocurrent by increasing the thickness of the first layer and by utilizing reflected light from the substrate surface to increase the amount of light absorbed by the first layer. has been done.

However, since the internal electric field strength of a-5iGe is weaker than that of a-5i, if a thick single layer is used, the generated electron/hole pairs will undergo recombination before reaching the n and p junctions, respectively. As a result, high efficiency could not be obtained.

Figure 2 shows the change in spectral sensitivity when blue light with a wavelength of 450 nm (or scattered light bias from the back side) is simultaneously irradiated as bias light in the measurement of spectral sensitivity by bonding the first layer made of a-5iGe. ,
From this figure, it can be seen that the sensitivity on the long wavelength side is significantly improved by blue bias light. One is pi
An extremely high resistance region existed at the p/i interface of the n-cell, but the blue bias light causes photoconduction and the electrical resistance decreases, making it easier for holes generated by the red monochrome light to reach the 9th layer. and the internal electric field of the pin junction is n
It is thought that this is because the current flows easily due to the electric field mobility of the holes and electrons because it is concentrated only at the /i interface.

As is clear from the structure shown in Figure 1, by creating a structure that allows light to enter from the front and back sides of the solar cell, direct sunlight enters the front side, but scattered light enters the back side. . There is an extremely high probability that the long wavelength light component of the light will also enter the back side due to scattering. Therefore, by using a module sandwiched between glass 101 and glass 17 as the cell assembly material, scattered light mainly consisting of long wavelength light components enters from the back side. This scattered light acts as bias light for the first layer of the tandem structure cell, and lowers the electrical resistance of the p/i interface in the same way as the bias light for the first layer shown in FIG. For this reason, the long-wavelength photosensitivity to incident light from the surface side increases, and as a result, even when using a-5iGe with insufficient film quality, a sufficient photocurrent can be generated. This helps improve the efficiency of tandem cells.

In the above embodiment, an example was shown in which the present invention was applied to a PIN three-layer tandem structure, but even when applied to an N1P three-layer tandem structure, the present invention is useful for improving the n/i interface, and similar effects can be expected. Further, the present invention is not limited to a three-layer tandem structure, but can be similarly applied to a two-layer, four-layer, etc. structure. In addition, it is effective not only in a tandem structure but also when used only in a long wavelength light cell with a structure in which wavelength division is performed by a filter mirror. Helpful for improvement.
