1. Annealing of Cu2ZnSn(S,Se)4 Thin Films : A Study of Secondary Compounds and Their Effects on Solar Cells
Abstract : Kesterite Cu2ZnSnS4 (CZTS) is interesting as a sustainable photovoltaic technology due to its earth-abundant elements and suitable semiconducting properties. To date, a record efficiency of 12.6% has been achieved but further improvements are required to reach high efficiency for industrial implementation. READ MORE

2. Teachers' Retention in Tanzanian Remote Secondary Schools : Exploring Perceived Challenges and Support
Abstract : Teacher retention is a global challenge, and many developed and developing countries are struggling to staff and retain teachers in schools, particularly in low-performing, remote, and less desirable areas. In most of these countries, Tanzania in particular, the efficacy of fiscally inclined teachers’ retention strategies continues to be dubious. READ MORE

3. Microscopic Characterisation of Solar Cells : An Electron Microscopy Study of Cu(In,Ga)Se2 and Cu2ZnSn(S,Se)4 Solar Cells
Abstract : The sun provides us with a surplus of energy convertible to electricity using solar cells. This thesis focuses on solar cells based on chalcopyrite (CIGSe) as well as kesterite (CZTS(e)) absorber layers. These materials yield record efficiencies of 20.4 % and 11. READ MORE

4. Defect Engineering in Kesterite Materials for Thin Film Solar Cells
Abstract : Cu2ZnSnS4 has great potential to be applied as an earth abundant and non-toxic absorber material in thin film solar cells, based on its suitable optical properties. However, several challenges have prevented the achievable efficiencies from exceeding 12.6 %, which is well below marketable efficiencies compared to competing solar cell technologies. READ MORE
