Dyesol Ltd (ASX:DYE) (OTCMKTS:DYSOY) Managing Director Richard Caldwell speaks with ABN Newswire about the recent patent application for improving the efficiency of the perovskite solar cell, and the UK funding body approving a grant of GBP800,000 for research and development.
About PEROVSKITE SOLAR CELL TECHNOLOGY
Perovskite Solar Cell (PSC) technology is a photovoltaic (PV) technology based on applying low cost materials in a series of ultrathin layers encapsulated by protective sealants. Dyesol’s technology has lower embodied energy in manufacture, produces stable electrical current, and has a strong competitive advantage in low light conditions relative to incumbent PV technologies. This technology can be directly integrated into the building envelope to achieve highly competitive building integrated photovoltaics (BIPV).
The key material layers include a hybrid organic-inorganic halide-based perovskite light absorber and nano-porous metal oxide of titanium oxide. Light striking the absorber promotes an electron into the excited state, followed by a rapid electron transfer and collection by the titania layer. Meanwhile, the remaining positive charge is transferred to the opposite electrode, thereby generating an electrical current.
