Considering the Asia – Pacific Solar Research Conference in Canberra, Anita Ho-Bailie, a senior research fellow at the Australian Centre for Advanced Photovoltaics of ACAP, confirmed that her group at UNSW has accomplished the biggest efficacy rating with the biggest perovskite solar cells till date.
The 12.1% efficacy rate was for a 16cm2perovskite solar cell; the biggest single perovskite photovoltaic cell registered with the biggest energy conversion efficacy and was independently certified by the international testing centre Newport Corporation in Bozeman, Montana. The novel cell is at least 10 times greater than the present certified high – efficacy perovskite solar cells.
Her group has also accomplished an 18% efficacy rating on a 1.2cm2singular perovskite cell and an 11.5% for a 16cm2four cell perovskite small module, both independently registered by Newport. “It is an extremely hot region of research with multiple terms competing to enhance photovoltaic design,” says Ho – Baillie. “Perovskitescame out in 2009 with an efficacy rating of 3.8% and have since grown in bounds and leaps. Such results place UNSW amongst the finest groups in the world releasing state – of – the – art high performance perovskite solar cells. And I consider we can obtain 24% within a year or so.”
Perovskite is a created compound where a hybrid organic and inorganic tin or lead halide – based substance function as the light generating active layer. They are the rapid advancing solar technology till date and are impressive as the compound is economical and simple to manufacture and can be also placed onto surfaces.
“The spontaneous solution deposition of perovskite makes it feasible to spray – coat, paint or print on solar cells,” says Ho – Baillie. “The variations of chemical compositions also enables cells be transparent or make of distinct colours. Think of being able to cover each surface of buildings, cars and devices with solar cells.”
Most of the global commercial solar cells are prepared from a refined, exceedingly purified silicon crystal and like the most effective commercial silicon cells known as PERC cells, required to be baked above 800 degree Celsius. The tricky part of this study is expanding a sleek layer of perovskite crystals so the leading solar cells absorb a maximum volume of light. Globally, engineers are functioning to prepare regular and smooth layers of perovskite with big crystal grain sizes in order to enhance photovoltaic yields.
Ho – Baillie, who gained her PhD at UNSW in 2004, is a prior chief engineer for Solar Sailor, an Australian company that incorporates solar cells into purpose – designed commercial marine ferries that presently ply waterways in Sydney, Hong Kong and Shanghai.The association is funded by an annual grant from ARENA and partners comprise Arizona State University, Trina Solar and Suntech Power
