Abstract: A solar cell is a device
that absorbs light energy to generate electrical energy. A typical example of a
solar cell is the quantum dot solar cell (QDSC), which consists of three main
components: (i) fluorophore: the component that absorbs light and generates
excited state electrons and holes, (ii) photoelectrode: the component that
transports the excited state electron and prevents recombination of excited
state electrons and holes, and (iii) electrolyte: the component that
replenishes the vacancy left by the excited electron in the hole. Despite the
increasing number of research in the QDSC field, to date, a device with
significant photovoltaic efficiency has not been developed. In this study, the
mechanism of electron transport in a zinc oxide (ZnO) photoelectrode was
investigated. Two ZnO layers were fabricated using thermal evaporation method
at different vacuum pressures (5 × 10-4and 5
× 10-5
Two solar cells were fabricated using ZnO as photoelectrode, lead sulphide as
fluorophore, and a mixture of carboxymethyl cellulose and polyvinyl alcohol as
electrolyte. The cell which utilized the ZnO fabricated under 5 × 10-5
Torr showed the highest efficiency (h =
0.98%), with fill factor = 22.07%, short circuit current = 2.85 mA/m2,
and open circuit voltage = 80.719 mV.
Keywords: efficiency, fluorophore, thermal evaporation, photoelectrode, zinc oxide
