Multi-layered photovoltaic element having at least three unit cells |
摘要 |
A multi-layered photovoltaic element obtained by stacking at least three cells for photovoltaic generation. A second cell formed adjacent to a light incident-side cell and adapted to receive light which has passed through the light incident-side cell includes an i-type semiconductor layer having a band gap falling within a range of 1.45 eV to 1.60 eV. The i-type semiconductor layer consists essentially of a silicon-germanium-containing amorphous material.
