Are new solar panel stickers durable enough to replace the old technology solar panels?

Reading Time: 3 minutes

Solar panels are made out of silicon, which is the most common semiconductor material used in solar cells. The sand used in the production of the silicone is easily available, and only the process of creating a solar panel is expensive. Moreover, the life span of a traditional solar panel is around 30 years. The process of making a solar panel is expensive, but not the materials used in its production.

New solar panels have different structures and are composed of polymeric films. Polymeric films are a continuous material that can be as thick as 0.008 inches. Polymer films are made of synthetic, natural, and artificial films. The process of converting plastic into polymeric films depends on the usage of such polymers. The process is different for making beverage containers and more complex for creating a solar panel. Scientists at the Massachusetts Institute of Technology (MIT) devised a solution in the form of portable, lightweight new solar panels known as a sticker solar panels. The benefits of this new technology include portability, lightness, and structure. Nevertheless, both panel systems use different technologies and materials during production.

What both types of panels have in common is that they produce cheaper energy while emitting no pollution.Renewable sources of energy have a positive impact and are the solution for generations to come.

Additionally, new solar panels are composed of plastic and recycled plastic materials. As a result, it helps to preserve the environment while also making good use of discarded plastic junk. In these terms, both old solar panels and new sticker panels, are extremely sustainable and eco-friendly. The abundance of sand and recycled plastic will ensure that there are enough materials to start mass production of these regenerative sources of energy. Nevertheless, there could be an enormous amount of junk panels due to their 25–30-year life span. Sticker panels appear to be a more reasonable solution in terms of weight and ease of disposal. Perhaps, scientists will discover a way to improve the sticker panels so that they can be reused them multiple times. Technology appears to be making significant strides toward resolving all of the issues that have arisen. I am certain that within the next 5–15 years, scientists will find a way to reuse sticker panels, decrease the costs of disposing of them, or find a solution to tackle such an issue.

Comparing the costs of old solar panels and sticker panels, we can see similarities. Of course, when mass production takes place, panels should become more affordable and easily available. Due to the novelty of sticker panels, the prices are still high. The materials used in its production cost nothing; all the costs are absorbed by the production stage, which implies new technology to do so. Of course, stickers are a relatively new idea and haven’t been widely available. For example, a stick panel can be purchased on Amazon for 638 zl and measures 95 cm by 53 centimeters. The dimensions are ideal for a boat solar panel or an off-grid living vehicle. The price of a solar panel with similar dimensions is 909 zl; however, prices vary between manufacturers.

In my opinion, solar panels are one of the most underappreciated technological innovations. More resources should be invested in solar energy research and automation to reduce costs and increase availability. MIT made great progress by creating lightweight sticker panels, and if it weren’t for them, the junk panels would accumulate over the years without a solution to recycle millions of tons of obsolete solar panels. MIT, thank you for creating a more efficient way to generate renewable sources of energy!

HOW 4D PRINTING CAN IMPROVE OUR LIVES?

Reading Time: 3 minutes

INTRODUCTION

Although the 3D printing has been existing for nearly 30 years now, when the Additive Manufacturing industry is still discovering new materials and ways to apply them, a new technology has started to appear, and its name is 4D printing

WHAT IS 4D PRINTING

In a nutshell, 4D printing is a process of printing a 3D object, that is able to change its shape, color, or other properties over time, after being influenced by an external energy input, such as temperature or light, and even more. The main research lab, that pioneers many 3D, and now 4D technologies is the MIT’s Self-assembly lab. Their goal is to combine technology and design to invent self-assembly and programmable material technologies aiming at reimagining construction, manufacturing, product assembly and performance.

THE MAJOR DIFFERENCE BETWEEN 4D AND 3D PRINTING

The main reason why 4D can be better than 3D is its lack of rigidity. A once printed 3D object cannot change its form, while 4D is its exact opposite. 4D printing uses the so-called “smart materials” such as hydrogel or a shape memory polymer that use their thermomechanical properties and other material properties to remember and change shape.

PROS AND CONS OF 4D PRINTING

SIZE CHANGING

Thanks to the ability of changing shapes, such as shrinking and folding, we can now print objects (that a 3D printer would require from us to print many parts) in one go!

SHAPE REMEMBERING MATERIALS

With the usage of Multimaterial Shape Memory Polymers, that are capable of “remembering” a shape, we can create objects that transform themselves in response to external energy output.

TIME

Although 4D shape-shifting is simply amazing and has many possibilities, it requires a lot of time to do so. If a hand sized cube takes up to two hours to change its shape, we can imagine how much it would take for a large sized object, such as furniture to do so.

WATER-LOSS AND FORM-HOLDING

Despite the fact that by adding water, an object can build itself, shrink or grow, it also means that the polymers, can lose new characteristics by losing water through evaporation, which brings a lot of risk that we didn’t have to deal with up till now.

TEMPERATURE NEEDED TO TRANSFORM

Even though heat 4D printing seems to be more reliable right now, as it needs less time to transform, and do not possess a risk of losing it characteristics, (unless deformed by a human or affected by extreme heat) it requires really high temperature that varies between 50-70⁰C to transform, which limits its everyday use.

HOW CAN 4D IMPACT OUR LIVES?

Although 4D printing is still in its infancy, and doesn’t have many practical uses right now, it has a lot of potential to influence our lives. It will for sure have a huge impact on medication, such as self-reconfiguring and self-folding protein, designing sents or make devices that will change shape and release medicine when the patient gets fever. It can also influence other sectors such as fashion, by creating self-readjusting shoes that will transform depending on our action. We will also be able to find them at architecture, for example there is a possibility of self-folding bridges.

CONCLUSION

The current 4D printing is still in its early days and although right now there aren’t many practical ways of using it, we can still see the potential that it brings for improving a lot of aspects of our lives. Over time, it will become very important in many major sectors of education and architecture.
