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.
Challenges in monocrystalline and multicrystalline silicon ingot production are discussed. The choice of the crystallization process plays a crucial role in determining the quality and performance of the photovoltaic (PV) silicon ingots, which are subsequently used to manufacture solar cells.
Monocrystalline solar cells reached efficiencies of 20% in the laboratory in 1985 (ref. 238) and of 26.2% under 100× concentration in 1988 (ref. 239). In this period, the efficiency of industrial solar cells slowly grew from 12% to 14.5%.
The potential of mc-silicon is even higher; about 20% have been demonstrated recently for laboratory cells . Such an improvement of the efficiency would greatly increase the commercial viability. The performance of multicrystalline solar cells is mainly limited by minority carrier recombination.
Techniques for the production of multicrystalline silicon are simpler, and therefore cheaper, than those required for single crystal material. However, the material quality of multicrystalline material is lower than that of single crystalline material due to the presence of grain boundaries.
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.

Both monocrystalline and multicrystalline silicon (mc-silicon) are used with an increasing share of mc-silicon because of the higher cost reduction potential [2]. The solar conversion efficiencies of commercial mc-cells are typically in the range of 12–15% and up to 17% have been obtained by more sophisticated solar cell designs [3], [4].
Crystal growth processes of multicrystalline silicon and their potential for further development are reviewed. Important parameters for the assessment of the final efficiency of the solar cells and the production yield are the bulk lifetime and the mechanical stability.
