Single crystalline silicon is usually grown as a large cylindrical ingot producing circular or semi-square solar cells. The semi-square cell started out circular but has had the edges cut off so that a number of cells can be more efficiently packed into a rectangular module.
The majority of silicon solar cells are fabricated from silicon wafers, which may be either single-crystalline or multi-crystalline. Single-crystalline wafers typically have better material parameters but are also more expensive. Crystalline silicon has an ordered crystal structure, with each atom ideally lying in a pre-determined position.
Device designs that avoid diffused emitter regions and direct metal-absorber contacts, commonly denoted as passivated contacts, are key enablers for a further increase of efficiency. So far, three concepts have been developed that enable junction formation in crystalline silicon solar cells without diffused emitters.
The first practical crystalline silicon solar cell was developed using the Czochralski method in 1954 by a team of researchers at Bell Laboratories in the United States and the efficiency was around 6% (Loff, 2023).
The efficiency of silicon (Si)-based solar cells has nearly reached its maximum capacity at approximately 25%. Conversely, III-V compound semiconductor-based solar cells have consistently exhibited enhancements in performance, increasing by approximately 1% annually. These solar cells recently accomplished a remarkable efficiency of 47.1%.
