Perovskite Solar Cells Beat New Records - In The Lab
News from the frontier of perovskite solar cell research:
A team at Chinas Huazhong University in Wuhan, working with pioneer Michael Grätzel at Lausanne, have fabricated cells without a hole transport layer, and done it by dripping a solution of the ingredients on to a carbon mesh. The cells have gone 1000 hours, a typical years exposure outdoors, without degradation.
Meanwhile researchers at Sheffield University in England have made a working cell simply by spraying a solution of their patent gunk on to a surface could be anything really, flat or curved.
Neither cell is efficient. At 12.8% and 11% respectively, they are well behind the perovskite solar cell record of 19.3%, let alone the 21% of production monocrystalline silicon cells. So why the fuss? Isnt this another scheme which looks good in the lab but fails in the market, defeated by silicon through simply getting cheaper?
