Researchers in Australian National University have also worked on a similar productivity improvement perovskite. The ones that researchers have worked on would be such that they lead to an improvement of around 26 percent in efficiency in solar energy harnessing and conversions (Peleg, 2017b). This according to the researchers is a new world record when it comes to efficiency improvement. In the research, perovskite cells were used in conjunction with silicon solar cells, similar to the research conducted in Purdue University. The silicon cells are much more capable compared to the perovskite cells when it came to absorbing solar light. This means that when the perovskite was placed atop the silicon cells, then a very high voltage is generated here. This generation is seen to be a direct effect of the circumventing of the existing solar inefficiencies because of the use of one cell only (Meija et a., 2017). It is a low-cost alternative with which researchers believe they can achieve as much as 100 percent efficiency improvement. One hundred percent in energy improvement is something that is currently not feasible and at best efficiencies of around 20 percent are reported. The researchers here, aim to reach 30 percent of improvement in energy productivity and efficiency as a first stop and want to go beyond that (Peleg, 2017).
Research works in Korea have implemented a 12.2 percent efficiency improvement in perovskites. The Ulsan Institute of Science and Technology worked on perovskite cells and were able to implement cells with more than 21.2 percent in efficiency. The stability is also quite high, as a 93 percent performance was reported. This performance was recorded within a 1,000 hour of exposure to adequate sunlight and this is promising. A newer form of manufacturing of perovskites is also prepped at the moment in Korea. The UNIST University in Korea and the Korean Institute of Chemical Technology KRICT has come together into creating this newer manufacturing method. ‘Hot pressing’ as this method is called will improve usability of perovskites as it makes them more stable and much more energy efficient (Peleg, 2017).
In research done by the Northwestern University and the Argonne National Labs, it was identified that Perovskite’s life cycle assessment LCA showed that Perovskites had to be studied better before their use is tapped into. Compared to the existing solar cells, perovskites were seen to have a very shorter lifetime and more emission capability. This increases LCA concerns (Michaud, 2015).
