Abstract :
The electrical characteristics of InGaP n+/p/p+, solar cells are unstable under illumination below typically 200 K. We show that this effect is metastable. We demonstrate using capacitance and current–voltage measurements coupled with deep level transient spectroscopy that this metastability is a result of the presence of DX centers, associated with the donor impurities in the emitter.
