Abstract<\/b><\/h2>\n

Organolead<\/span>\u00a0trihalide perovskite solar cells have shown success as light absorbers in photovoltaic cells due to their efficiency increasing from 3.5% to over 20% within only five years. <\/span><\/p>\n

However, pinhole formation and incomplete coverage of solution-processed perovskite film results in increased current leakage, reducing efficiency. Hence the surface morphology of perovskite film is important for high performance of perovskite solar cells. <\/span><\/p>\n

Here the morphology is carefully controlled by varying processing conditions, perovskite films were prepared using two different lead sources: lead acetate (Pb(<\/span>OAc<\/span>)2) and lead iodide (PbI2), with methylammonium iodide (CH3NH3I) as the source material. <\/span><\/p>\n

The structural, optical and absorbance properties of the perovskite films varied with the lead sources used, perovskite from a Pb(<\/span>OAc<\/span>)2.3 H2O source annealed at 90oC gave the best structure compared to Pb(<\/span>OAc<\/span>)2.3H2O annealed at 80oC and anhydrous Pb(<\/span>OAc<\/span>)2 annealed at 90oC.<\/span><\/p>\n

Introduction<\/span><\/span><\/strong><\/h2>\n

The growing global population and\u00a0<\/span>industrialisation<\/span>\u00a0have led to the continuous increase in demand for energy. Global energy demand is predicted to be as high as 1GW\/day, which places substantial pressure on current energy infrastructures (Wang, Wright, Elumalai & Uddin, 2016). <\/span><\/p>\n

The supply of fossil fuels is consistently declining and cannot satisfy the huge energy demands in the nearest future. <\/span><\/p>\n

These challenges, in addition to the danger of climate change, have necessitated the development of energy from renewable energy sources, which are environmentally friendly and sustainable. <\/span><\/p>\n

Among the probable renewable energy technologies, photovoltaic (PV) solar cells, which convert sunlight into electricity, provide a promising solution; solar power is the most abundant energy source in the world (Zulkifli &\u00a0<\/span>Bahtiar<\/span>, 2016).<\/span><\/p>\n
