Transducing components. Ian Sinclair, in Passive Components for Circuit Design, 2001. Photocells. A photocell is a light-to-electrical transducer, and there are many different types available. Light is an electromagnetic radiation of the same kind as radio waves, but with a very much shorter wavelength and hence a much higher frequency.
The commonly used barrier coating materials are ceramics, such as silicon oxide (SiO x), silicon nitride (SiN x) and aluminum oxide (AlO x). These materials have strong barriers to gas and moisture diffusion as well as high optical transparencies. 41 However, a single barrier coating is usually inadequate for device application. For example, the SiO x coated PET …

By far the most widely used III-V solar cell is gallium arsenide (GaAs), which has a band gap of 1.42 eV at room temperature. It''s in the range of the ideal bandgaps for solar absorption, and it has the bonus of having a direct-gap absorption, which means that the lattice vibrations don''t matter in deciding whether or not light will get absorbed.
There are not many kinds of organic materials used as ETLs in PSCs, because the solvents of perovskites are hydroxybutyrolactone (GBL), N,N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), etc., which also have good solubility for many organic materials. If the organic materials are used as ETL in conventional PSCs, the subsequent spin coating of …
