Printed light-weght perovskite solar cells

We are focused on perovskite-based solar printing equipment. These are batteries with the best ratio of efficiency to weight. Now the efficiency is about 17%, and the minimum thickness is 10 microns .

We can automate the process of producing a solar cell using the semblance of printing elements. Reagents and substrates are loaded onto which layers of solar cells are applied. We create a laboratory model, which at the very beginning of development gives the final product. In this case, the need for staff can be minimized. All this significantly reduces costs, which can bring the cost price to $ 0.3 per watt.
An efficiency of about 17% has been achieved, calculations show that it is possible to exceed 30% in the future.

Solar panels can be printed on a variety of substrates, including on a curved surface. On flexible substrates it can be a hat or a backpack with built-in solar cells. Perovskite material with an efficiency of 20% and a lifetime of about 4 years. In the future, we plan to obtain an efficiency of 25% of perovskite batteries. Now on the market are backpacks with battery efficiency of about 10%
The cost price of 400 dollars is already sunny clothes like jackets, vests.
For the manufacture of 1 square meter you need from 10 to 20 USD. It takes about a year and a half and about 600-900 thousand USD to go into industrial production. We need to increase the guaranteed period of work to 8-9 years and repeatable efficiency from 14 to 18% over a large area and prevent production defects. In some experiments, my efficiency was up to 21%.
