SUMMARY:The future of clean energy? The physics of perovskite solar cells

DESCRIPTION:Saving the planet from environmental meltdown would be a lot e
 asier if it weren’t so expensive. \n\nThe sun is big and powerful\, henc
 e converting the sun’s energy directly into electricity has always appea
 led to us. We will need photovoltaic technologies to provide some portion 
 of our energy in the coming years if we are to make any kind of progress t
 owards meaningful targets in sustainability. ‘Third generation’ solar 
 technologies embody the current scientific effort to reduce cost and incre
 ase the efficiency of new types of solar panels. In our quest for the lowe
 st dollar-per-Watt ratio\, scientists have come up with an extraordinary a
 nd creative assortment of new structures and scientific advances. \n\nThis
  talk will give an overview of some of these remarkable technologies – p
 olymer solar cells\, quantum dot solar cells\, dye-sensitised solar cells\
 , for example. In particular\, I will recount my most recent work on the f
 undamental physics of the rising star in this field\, the perovskite solar
  cell\, and explain how its working mechanisms can be illuminated through 
 the use of ultrafast femtosecond transient absorption.\n
