Photovoltaic silicon ingots can be grown by different processes depending on the target solar cells: for monocrystalline silicon-based solar cells, the preferred choice is the Czochralski (Cz) process, while for multicrystalline silicon-based solar cells directional solidification (DS) is preferred.
Crystalline silicon solar cells are today’s main photovoltaic technology, enabling the production of electricity with minimal carbon emissions and at an unprecedented low cost. This Review discusses the recent evolution of this technology, the present status of research and industrial development, and the near-future perspectives.
PV Solar Industry and Trends Approximately 95% of the total market share of solar cells comes from crystalline silicon materials . The reasons for silicon’s popularity within the PV market are that silicon is available and abundant, and thus relatively cheap.
Silicon-based solar cells can either be monocrystalline or multicrystalline, depending on the presence of one or multiple grains in the microstructure. This, in turn, affects the solar cells’ properties, particularly their efficiency and performance.
The importance of crystallization methods in solar cell silicon ingot quality. The effects of the Czochralski (Cz) and directional solidification (DS) methods on microstructure and defects are reported. Challenges in monocrystalline and multicrystalline silicon ingot production are discussed.
Technically, a silicon wafer is a solar cell when the p–n junction is formed, but it only becomes functional after metallisation. The metal contacts play a key role in the production of highly efficient and cost-effective crystalline Si PV cells.
