摘要：
A photovoltaic element with a low shadow, a high energy conversion efficiency, a high freedom in dimension and a high reliability with prolonged use is provided. The photovoltaic element comprises a photovoltaic layer having a first semiconductor junction layer for generating an electromotive force, a current collecting electrode provided at the light incident side of the photovoltaic layer, and a bypass diode connected in parallel, wherein the bypass diode is provided under the current collecting electrode as a bypass diode layer having a second semiconductor junction layer other than the first semiconductor junction layer of the photovoltaic layer.
