<p>PURPOSE: A photovoltaic module and a manufacturing method thereof enable a user to feel less visual fatigue by forming the photovoltaic module to have the color of light yellow or bright green. CONSTITUTION: A first electrode is formed on a substrate. A photoelectric conversion layer is formed on the first electrode and converts irradiated light into electric power. The photoelectric conversion layer includes a first type semiconductor layer, a second type semiconductor layer, and an intrinsic semiconductor layer. A second electrode is formed on the photoelectric conversion layer. The first electrode, the photoelectric conversion layer, and the second electrode have multiple unit cells connected to each other in series. The unit cells have a color in the range of a*>=0 and 0<=b*<=62.2 on a CIE LAB color coordinate. [Reference numerals] (AA) Solar cell light-absorbing zone a^* >=0, b^* >= 0; (BB) I layer color coordinate expression by thickness b^*=54.12 (opening ratio 0); (CC) Move farther with a larger opening ratio (fixed slope, y intercept↓); (DD) Move farther with a thinner thickness (fixed slope, y intercept↑); (EE) B^*=Ka^* - M color coordinate expression by opening ratio (i layer thickness: 2000A)</p> |
