CdTe-based thin film photovoltaics: Recent advances, current …
The device physics of film photovoltaic devices follow those for p-n heterojunctions, however especially in capacitance, cells having buffer layers also share features with (very leaky) metal-insulator-semiconductor (MIS) structures [17].To date photocarrier collection from the TCO and buffer layers has been negligible, thus both …
Intrinsic Carrier Concentration
Intrinsic carriers are the electrons and holes that participate in conduction. The concentration of these carriers is contingent upon the temperature and band gap of the material, thus affecting a material''s conductivity. Knowledge of intrinsic carrier concentration is linked to our understanding of solar cell efficiency, and how to …

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 …
Quantum Efficiency
The "quantum efficiency" (Q.E.) is the ratio of the number of carriers collected by the solar cell to the number of photons of a given energy incident on the solar cell. The quantum efficiency may be given either as a function of wavelength or of energy. If all photons of a certain wavelength are absorbed and the resulting minority carriers are ...
