TL;DR: In this article, a 2nd-law analysis performed on the closed cyclic process indicates a maximum exergy conversion efficiency of 29% (ratio of Δ G 298 K °| H 2 + 0.5 O 2 → H 2 O for the H 2 produced to the solar power input), when using a solar cavity-receiver operated at 2300 K and subjected to a solar flux concentration ratio of 5000.

01 Aug 2002TL;DR: In this article, a substrate for a solar cell is provided which comprises a support having a metal surface and a zinc oxide film formed on the metal surface, having a water content of 7.5 H 10-3 mol/cm3 or less.
Abstract: A substrate for a solar cell is provided which comprises a support having a metal surface and a zinc oxide film formed on the metal surface and having a water content of 7.5 H 10-3 mol/cm3 or less, preferably 4.0 H 10-4 mol/cm3 or more. Thereby, the increase of series resistance and the generation of shunt are prevented and the efficiency such as Jsc and the chemical stability are improved, thus obtaining a solar cell with a zinc oxide film having optimal overall characteristics.
