摘要

We have theoretically investigated the effect of front electrode on the structure and performances of Gasub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"ix/i/subIninline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink" tex-math notation="LaTeX"$_{1-{x}}$ /tex-math/inline-formulaAssub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"iy/i/subSbinline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink" tex-math notation="LaTeX"$_{1-{y}}$ /tex-math/inline-formula thermophotovoltaic (TPV) cells. By sampling a comb-like electrode, it is clearly demonstrated here that the optimum grid separation inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink" tex-math notation="LaTeX"${d}_{G}$ /tex-math/inline-formula depending on the cell bandgap yields a quadratic function for a given spectrum illumination, while the desired coefficients are strongly temperature-dependent and can be well modeled by an exponential decay expression. Comparing with previous report with constant grid separation, the denser front electrode promises an inferior cell efficiency, but the similar phenomenological method can be still applicable to predict the structure and performance of Gasub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"ix/i/subIninline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink" tex-math notation="LaTeX"$_{1-{x}}$ /tex-math/inline-formulaAssub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"iy/i/subSbinline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink" tex-math notation="LaTeX"$_{1-{y}}$ /tex-math/inline-formula TPV cells for a given operation environment.
