The fundamental development of Cu2ZnSnS4 (CZTS) thin films by non-vacuum, liquid-based techniques have been investigated. CZTS is a quaternary semiconductor material consisting of earth abundant, low-toxicity materials. CZTS is a promising absorber layer material for thin film solar cells due to its optimal optical band gap of ∼1.5 eV and a large optical absorption coefficient of over 104 cm−1. CZTS...
The development of perovskite thin films by spin-coating, deposition techniques have been investigated. The methyl ammonium lead iodide (CH3NH3PbI3) perovskite has a direct band gap of 1.5 eV and a large absorption coefficient of over 104 cm−1. The perovskite absorber was deposited by a non-vacuum liquid-based coating method with chlorobenzene and without chlorobenzene by using Laurell Technologies...
Development of fabrication techniques to produce cost efficient Perovskite absorption layers via spin coating techniques using the WS650 spin processor (Laurell Technologies) were investigated. The methyl ammonium lead iodide (CH3NH3PbI3) perovskite was deposited on top of soda lime glass (SLG) substrates. Two ways of depositing CH3NH3PbI3 were explored. The two techniques used to create the perovskite...
