Dose anyone know that what is the newest generation of solar cells?
There are two main research directions for solar cells.
One aim is to get the highest possible efficiency. Here multijunction cells from III-V materials are the most up-to-date thing. I think the current record is 44.7% efficiency (http://phys.org/news/2013-09-world-solar-cell-efficiency.html), but I would not be surprised if that record has already been broken.
The other research direction is cost efficiency. Here people try to get CdTe to work in a reasonable manner (the efficiency is somewhere around 11.5% at the moment, but the cell is pretty cheap) or they try to realize transparent thin film cells which can be used more flexibly, for example in windows.
Thank you, but how about Perovskite-Based Solar Cells?
