(1) Dye-Sensitized Solar Cell (DSC). The DSC most commonly contains a layer of sintered TiO 2 nanoparticles (usually some tens of nm in size) about 10 μm thick (a few μm for a solid state cell) that acts to accept photogenerated electrons from the dye molecules and transport them to the (conducting glass) contact. Values of IQE close to 100% ...
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron …
A cross-sectional view of the Si solar cell structure that has been used in production up to the present is given in Fig. 3a 18.For crystalline Si devices, a boule of B-doped p-type Si is grown using the Czochralski method and wafers are sawn from the boule.Crystalline (and multicrystalline) Si have an indirect energy bandgap resulting in a …

This tutorial uses a simple 1D model of a silicon solar cell to illustrate the basic steps to set up and perform a device physics simulation with the Semiconductor Module. A user-defined expression is used for the photo-generation rate and the result shows typical I-V and P-V curves of solar cells.
While PV semiconductor materials are not limited to silicon, the dominance of silicon in the PV market has led to our particular emphasis of that material for the PVCDROM. For the purposes of the website, the material presented specifically focuses on silicon-based solar cells, unless otherwise noted.
