摘要:
This invention relates to a high efficiency solar cell with a novel architecture. In one embodiment, the solar cell is comprised of a high energy gap cell stack and a dichroic mirror. The high energy gap cell stack is exposed to solar light before there is any splitting of the solar light into spectral components. Each cell in the high energy gap cell stack absorbs the light with photons of energy greater than or equal to its energy gap, i.e., the blue-green to ultraviolet portion of the solar light. Each cell in the high energy gap cell stack is transparent to and transmits light with photons of energy less than its energy gap. Spectral splitting is then performed by means of the dichroic mirror on the remaining light, i.e., the light transmitted by the high energy gap cell stack.

Applying a D. C. glow discharge to a heated glass substrate in an evacuated chamber to which certain amounts of oxygen and a volatile tin composition have been added, produces a glass substrate coated with a transparent, conductive coating of tin oxide wherein the surface region of the glass beneath the coating has been depleted of alkali metal ions.
摘要:
A D.C. glow discharge is applied to a heated glass substrate coated with a conductive layer in the form of a pattern in an evacuated chamber, to which chamber certain amounts of oxygen and a volatile tin composition have been added. A glass substrate is produced which is coated with a patterned, transparent, conductive coating of tin oxide, wherein the surface region of the glass has been depleted of alkali metal ions.
