(b) Background technology Conventionally, a-8i films have been produced using the so-called plasma CVD method, in which silane (SiH2) gas is decomposed by glow discharge, or silicon (Sl) cugetto is decomposed using argon (Ar) containing hydrogen.
It is manufactured by a gas spacking method, and photovoltaic elements using the a-8i film have been manufactured with photoelectric conversion efficiencies exceeding 8%. However, since the optical energy gap of the a-8i film used in photovoltaic devices to obtain good photovoltaic conversion efficiency is constant at approximately 1.75 eV, long-wavelength light has a small energy and is used in the a-8i film. It passes through without being absorbed. In addition, short wavelength light is a
However, since the energy of light is too large, all excess energy beyond the optical energy gap of the a-8i film becomes an energy loss. In order to solve the above-mentioned drawbacks, so-called 3S Ic, in which carbon is added to the a-8i film, has been developed.
Attempts have been made to effectively utilize short wavelength light by widening the optical energy gap using a film, and by using a so-called a-8l film, which is an a-8i film doped with kermanillam (Ge), to reduce the optical energy gap. Attempts have been made to effectively utilize long wavelength light. However, the a-
In the 8iC film and the a-8iGe film, the photoelectric conduction area is greatly reduced due to addition, so the problem is that the effect of enlarging or reducing the optical energy gear knob does not contribute significantly to the photoelectric conversion efficiency. There was a point.
