(oral talk) Impact of upconverting atomic layer deposited Er2O3 on Si solar cell surface passivation

Research output: Contribution to conferenceAbstractScientificpeer-review

Abstract

Si solar cell cannot absorb photon with energy less than 1.1 eV bandgap. Er2O3, as a solution, absorbs low-energy photons and emits higher-energy photons. Si solar cell also suffers from recombination of photogenerated charge carriers at surface. We study surface passivation property of (i) bare ALD Er2O3 or Er2O3 deposited on top of (ii) SiO2 or (iii) Al2O3 by measuring minority carrier lifetime.
