How a Solar Cell Works
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 …

Challenges, myths, and opportunities in hot carrier solar cells
In studying diode solar cells, it is important to realize that the normal p–n junction diode operates in a dramatically different fashion than the p–n junction solar cell. The normal p–n junction diode is classically referred to as a minority carrier device in that carriers move from high density to low density regions when the device is turned on (V …

The Role of Thermalization in the Cooling Dynamics of Hot Carrier Solar ...
1 Introduction. Hot carrier solar cells (HCSC) have been proposed as a means to overcome the Shockley Queisser (SQ) limit, [] the theoretical efficiency limit for a single junction solar cell. [2, 3] The rationale behind the SQ limit is threefold: One photon can only create a single electron-hole pair, the solar cell is under unconcentrated …
