【００１９】
（７） 前記半導体への光の入射角（半導体表面に対する角度、以下同じ）が９０°での光電変換効率をＲ90とし、光の入射角が５２°での光電変換効率をＲ52としたとき、Ｒ52／Ｒ90が０．８以上である上記（１）ないし（６）のいずれかに記載の太陽電池。[0019]
(7) The photoelectric conversion efficiency at an incident angle of light to the semiconductor (an angle with respect to the semiconductor surface, the same applies hereinafter) at 90 ° is R 90, and the photoelectric conversion efficiency at an incident angle of light 52 ° is R 52 The solar cell according to any one of the above (1) to (6), wherein R 52 / R 90 is 0.8 or more.

このような半導体４を用いた太陽電池１では、半導体４への光の入射角（半導体表面に対する角度、以下同じ）が９０°での光電変換効率をＲ90とし、光の入射角が５２°での光電変換効率をＲ52としたとき、Ｒ52／Ｒ90が０．８以上程度となるような特性を有しているのが好ましく、０．８５以上程度であるのがより好ましい。このような条件を満たすということは、半導体４が光に対する指向性が低い、すなわち、等方性を有するということである。したがって、このような太陽電池１は、太陽の日照時間のほぼ全域に渡って、より効率良く発電することができる。このような太陽電池１は、例えば、次のようにして製造することができる。[0073]
In a solar cell 1 using such a semiconductor 4, the photoelectric conversion efficiency at an incident angle of light to the semiconductor 4 (an angle with respect to the semiconductor surface, hereinafter the same) is 90 ° is R 90, and the incident angle of light is 52 ° It is preferable to have the characteristic that R 52 / R 90 is about 0.8 or more, and more preferably about 0.85 or more, where R 52 is the photoelectric conversion efficiency of To satisfy such conditions means that the semiconductor 4 has low directivity to light, that is, it has isotropy. Therefore, such a solar cell 1 can generate power more efficiently over almost the entire sunshine hours. Such a solar cell 1 can be manufactured, for example, as follows.
【０１８１】
（評価）実施例１〜８において製造した太陽電池に、それぞれ、人工太陽灯の光を照射し、このときの光電変換効率を測定した。なお、半導体表面に対する光の入射角度は、９０°と５２°とに設定し、光の入射角度が９０°のときの光電変換効率をＲ90とし、５２°のときの光電変換効率をＲ52とした。これらの実験および評価の結果を表１に示す。[0181]
(Evaluation) The solar cells manufactured in Examples 1 to 8 were each irradiated with the light of an artificial solar lamp, and the photoelectric conversion efficiency at this time was measured. The incident angles of light with respect to the semiconductor surface are set to 90 ° and 52 °, and the photoelectric conversion efficiency when the incident angle of light is 90 ° is R 90, and the photoelectric conversion efficiency when 52 ° is R 52 And The results of these experiments and evaluations are shown in Table 1.
