Marketing of perovskite panels in Europe at 170w / m2

[jean.caissepas]

A Polish company offers to adapt its cells to different supports (horizontal sunblind blades, etc.) under the form of a license:

No info on price and availability unfortunately ...

Uh, just a small remark: 170W / m² there is nothing exceptional ... Mine of 285 W is 1.64 m² or 174 W / m² ... and there are more than 300W for the same surface. .

Apparently, they are pure perovskite so without silicon!

Advantage:
- Lightness (they can be fixed on light vertically orientable slats)
- Flexibility (non-flat slats, ...)
- Price? (no info on that ...)

The most interesting advantage of perovskite cells is in my opinion and if I read correctly (quickly), better "capture" of light ... apparently you don't need to be normal in the sun to get good performance.

It would therefore be interesting to know at what angle / irradiation (in W / m2) we obtain the 170 W / m² that you advertise ... if it is at 500 W / m² or with a 60 ° angle yes it is exceptional compared to the existing.

If it is at 1000 W / m² and with an angle of 20 ° or less it is not much ...

Silicon cells are already light, flexible and inexpensive ...

What makes them rigid and heavy is the surface treatment applied to them ...

Perovskite or silicon pick up diffuse radiation. What matters is that the protective glass is not reflective. This is the case on all modules. to Christophe, if you look at the module closely, you will see that the surface does not seem perfectly smooth. It is to catch the light in all directions. The silicon wafer is also rough so as not to be a mirror.

I don't see the point of Perovskite, since in addition it contains lead except for very small sensors (for example for IOTs to avoid having to connect them to a socket)

Otherwise, as soon as you put the bouzin outside you need a good tempered glass window, otherwise it will give off the first hail falls.
