| Description | The project falls in the area of solar energy based renewable energy technologies and photovoltaic devices. Of all the renewable energy technologies, solar energy has the greatest potential as a world power source. For this reason, solar photovoltaic, the direct conversion of sunlight to electricity, is expected to play a significant role in future electricity supply. Solar cells based on perovskite semiconductors are generating huge interest for this purpose. However, the potentially enormous impact of low-cost perovskite solar cells has not been fully realised to date because of limited stability and concerns about the use of lead. This project focussed on addressing these bottlenecks. In particular, we focussed on the development of new lead-based and lead-free perovskites of enhanced stability and minimised environmental impact. Potential release of heavy metals (e.g. lead) into the environment in the event of integrity failure of the packaged cell has been investigated by the use of a new "green" lead scavenging scaffold. Key factors determining the stability of perovskite solar cells have been established. We have also elucidated the degradation of mechanism of tin perovskite materials under ambient operation conditions paving the way to more environmentally friendly stable solar cells. |
| Exploitation Route | The findings (e.g. mechanistic insights of stability / degradation pathways in tin perovskites) will help facilitate the development of a wide range of optoelectronic / electrical devices using lead-free tin perovskites - e.g. solar cells, field effect transistors, light emitting diodes etc. |

| Title | Driftfusion |
| Description | First official release of Driftfusion. The recent application of lead-halide perovskites as an active layer material in thin film semiconductor devices including solar cells, light emitting diodes (LEDs), and memristors has motivated the development of several new drift-diffusion models that can include the effects of both mobile electronic and ionic charge carriers. Here, we present Driftfusion, a versatile simulation tool built for simulating one-dimensional ordered semiconductor devices with mixed ionic-electronic conducting layers. Driftfusion enables users to simulate devices with virtually any number of layers and with up to four charge carrier species (electrons and holes by default plus up to two ionic species). The time-dependent carrier continuity equations are fully-coupled to Poisson's equation enabling transient optoelectronic device measurement protocols to be simulated. In addition to the material parameters, users have direct access to adapt carrier transport, recombination and generation models as well as the system boundary conditions. Furthermore, a graded-interface approach circumvents the requirement for boundary conditions at material interfaces and enables interface-specific properties, such as high rates of interfacial recombination, to be introduced. |
