Printed solar cells are paper-thin, lightweight and extremely inexpensive to produce. The cells are also flexible, so you can probably customize where or how you want the cells to be. Very cool if you ask me. This could bring light to the 1.3 billion people in the world currently living without any electricity. For the developed countries, it will be a great transition to cleaner source of energy.
Technology has enabled urban poor communities in India to access off-grid electricity, things like this can help our streets out too, bring down cost in places we can’t afford. Its success is due to its cost effectiveness and simplicity. A 10×10 solar cell film is enough to generate as much as 10-50 watts per square meter.
With these printed solar cells comes cons of course. The printer required to generate these cells is expensive. The printed cells are susceptible to the moisture and can cause lead contamination if they are broken. There are, however, companies working to alleviate these issues. they are trying out different solvents.
Printed solar cells are a huge step towards a clean, renewable energy source globally! This shit right here, can and will be making a huge impact on the world.
