Measuring just two micrometers thick, the photovoltaic cells are the thinnest and lightest ever produced, and the flexible solar cells also have one of the highest power-to-weight ratios ever achie.
Could solar cells be the thinnest & lightest solar cells ever produced?
Imagine solar cells so thin, flexible, and lightweight that they could be placed on almost any material or surface, including your hat, shirt, or smartphone, or even on a sheet of paper or a helium balloon. Researchers at MIT have now demonstrated just such a technology: the thinnest, lightest solar cells ever produced.
Are thin-film solar cells better than conventional solar cells?
Our approach decouples the solar cell manufacturing from its final integration,” Saravanapavanantham explains. The thin-film solar cells weigh about 100 times less than conventional solar cells while generating about 18 times more power-per-kilogram.
Could solar cells power the next generation of portable electronic devices?
Researchers at MIT have now demonstrated just such a technology: the thinnest, lightest solar cells ever produced. Though it may take years to develop into a commercial product, the laboratory proof-of-concept shows a new approach to making solar cells thatcould help power the next generation of portable electronic devices.
Could ultrathin photovoltaic cells be used for new uses?
Ultrathin, flexible photovoltaic cells from MIT researchcould find many new uses. The MIT team has achieved the thinnest and lightest complete solar cells ever made, they say. To demonstrate just how thin and lightweight the cells are, the researchers draped a working cell on top of a soap bubble, without popping the bubble.
But these ultrathin solar cells were fabricated using complex, vacuum-based processes, which can be expensive and challenging to scale up. In this work, they set out to develop thin-film solar cells that are entirely printable, using ink-based materials and scalable fabrication techniques.

These durable, flexible solar cells, which are much thinner than a human hair, are glued to a strong, lightweight fabric, making them easy to install on a fixed surface.
