The development of the PV industry is a vigorous competition between mono- and multi-crystalline silicon, as well as their crystal growth technologies, which will be focused on shortly. Crystal growth was not the single factor in getting the Holly Grail of the ultimate technology; the slicing and advanced solar cell concepts played crucial roles.

An urgent challenge to popularize diamond-wire-sawn single-crystalline silicon (DWS sc-Si) wafers to PV industry is to develop a proper texture process, specially eliminating its severe saw marks and forming uniform pyramid texture ing a simple pre-polishing step with TMAH plus routine texture process, the saw marks as well as …
Crystalline silicon. The light absorber in c-Si solar cells is a thin slice of silicon in crystalline form (silicon wafer). Silicon has an energy band gap of 1.12 eV, a …
Fig. 2. A typical firing profile of a commercial crystalline silicon solar cell. 2.3 Contact mechanisms A good front-contact of the crystalline silicon solar cell requires Ag-electrode to interact with a very shallow emitter-layer of Si. An overview of the theory of the solar cell contact resistance has been reported (Schroder & Meier, 1984).
Solar cell
Historical development. Bell Laboratory fabricated the first crystalline silicon solar cells in 1953, achieving 4.5% efficiency, followed in 1954 with devices with 6% efficiency [2,3].
Single crystal GaAs has the best efficiency that is close to the theoretical maximum with polycrystalline silicon at 20%. There are additional losses when the cells are assembled in to modules. Average production module performance summarized by IRENA are; thick polycrystalline silicon 14%, CdTe (9.5%) and CIGS (9%).
4 Single-Crystal Perovskite Solar Cells Architectures and Performances The structural configuration of the solar cell has a profound impact on the overall performances of the devices. A proper choice of the cell geometry should be done in order to mitigate the defects of the perovskite absorber and optimize the transport and collection of the charges to the …
