15. Direct synthesis of carbide-derived carbon monoliths with hierarchical pore design by hard-templating

Abstract

Carbide-derived carbon Monoliths (CDC-Ms) containing a multimodal arrangement with high volumes of micro- meso- and macropores are prepared by direct nanocasting of silica monoliths with polycarbosilane precursors. CDC-Ms show well-defined pore structures along with specific surface areas of more than 2600 m2 g−1 and overall pore volumes as high as 3.14 cm3 g−1. They exhibit advanced gas filtration properties compared to purely microporous materials due to enhanced storage capacities and kinetics as demonstrated by thermal response measurements based on InfraSORP technology.

Abstract

We investigate process sequences for obtaining solderable Al/Ni:V/Ag contacts to PERC-type crystalline Si solar cells by in-line Al evaporation. For a high cell efficiency the evaporated aluminum must be annealed at 350 °C for about 5 min. We find that annealing the Al/Ni:V/Ag metallization stack at temperatures above 150 °C destroys the solderability of the wetting layer. A solution for this problem is to first deposit the 2.5 μm Al layer by evaporation, then anneal the cell at 350 °C for 10 min, and finally sputter a double layer of Ni:V/Ag with respective thickness values of 200 nm and 25 nm. This process leads to a contact resistivity lower than 1 mΩcm2. The solderablility is proven by a peel force greater than 3 N/mm. We present a solderable PERC cell with Al/Ni:V/Ag rear side metallization and an efficiency of 18.9%.
