A novel approach to high performance and cost effective surface cleaning for high efficiency solar cells
In this work a novel one-step wet chemical surface cleaning approach with reduced cost of ownership for the industrial realization of high efficiency silicon solar cells is evaluated in a comparative study. For this purpose investigations concerning metal removal efficiency, impact on emitter sheet resistance change, carrier lifetime and on electrical cell data are performed. In all tests a comparable performance of SELURIS® to RCA [1] cleaning can be attained by an optimization of the SELURIS® formulation. On conventional Cz wafers of 156 mm size, peak efficiencies of 19.4 % for PERC devices with SELURIS® C-2000 series cleaning are achieved
Supramolecule command surface for liquid crystal alignment
Devices based on liquid crystal display technology, ranging from watches to flat panel displays, have proliferated over the past few decades and can now be found in all conceivable aspects of everyday life. It is surprising that a crucial part in the construction of such displays, namely the alignment layer, which dictates the surface alignment of mesogenic molecules, relies essentially on a mechanical rubbing process which was invented 100 years ago. In this paper, recent developments in the construction of alignment layers (also called command layers) based on the self-assembly of molecular and macromolecular components are discussed. Two topics are highlighted: (i) tuneable layers formed by hierarchical assembly of siloxane oligomers and phthalocyanine dyes on indium-tin-oxide surfaces and (ii) command layers formed by self-assembly of porphyrin trimers
