Elastic properties of polycrystalline silicon: experimental findings, effective estimates, and their relations

Abstract Silicon has a large impact on today’s world economy, also known as Age. For instance, it is an extremely important material for renewable energy systems like photovoltaics. Thereby, the use of polycrystalline silicon very wide range application. safe and economic operation with this material, most accurate prediction or measurement elastic properties possible interest in first place even if focus analysis inelastic behavior related reliability service life predictions. The problem effective parameters polycrystals question symmetry. single crystals obey cubic symmetry while aggregate, at random orientation its constituents, isotropy results. We here give synopsis established analytical approaches used to predict values well review experimental outcomes crystal aggregate level. In context present methods are applied predicted analytically results compared terms different data sets accessed. contrasted measured findings. resulting deviations discussed whereby reasons these discrepancies identified. application practicable calculations, implies that special emphasis must be placed origin data. mono- polycrystal both, findings, tabulated clear concise form, so they readily accessible design engineers.
