Scientists Develop Liquid Solar Cells

Liquid Solar Cells

Many alternatives to building solar cells have already been discovered, such as using spinach, but some recent discoveries by scientists at the University of Southern California (USC) invented a new type of solar cell made from nanocrystals.

These nanocrystals are apparently so tiny that you can fit 250 billion of them on a head of a pin, which is relevant because they can be made into an ink and then painted or printed on other surfaces. Theoretically you’ll be able to paint for example a plastic or even paper surface which would be able to gather solar power, and I’m sure you don’t need me to say how many possible benefits and practical applications this may have. These nano solar cells are not only convenient but also cheaper to produce than traditional silicon solar cells in use today.

“While the commercialization of this technology is still years away, we see a clear path forward toward integrating this into the next generation of solar cell technologies,” said Richard L. Brutchey, assistant professor of chemistry at USC. “…like you print a newspaper, you can print solar cells.”

There are a couple of downsides to this new discovery, as there always is. First these solar cells aren’t able to gather sunlight efficiently, and second the cadmium selenide coating used for them is toxic and can’t be used commercially. However it’s very likely that scientists will continue discovering alternatives to cadmium coating and improving the technology further, and in a few decades this will likely be a reality with everyday use.

How Renewable Energy Helps Protect The Environment

Solar Panel and Windmill

As a global community, one of the most serious threats that we are facing is of global warming and rapid climate shifts. These phenomenon which are apparently beyond our control, have been caused by our own negligence. The excessive burning of fossil fuels and unregulated power emissions are destroying the habitable environment of the planet, which is gradually making life difficult for human beings. In the wake of such a threat, power generation, is one of the most pivotal economic activities of our time, is emphasized to be carried out by means of renewable and eco-friendly sources.

Using solar panels and windmills is the best way to utilize the most efficient of renewable energy sources for generation of electricity. As solar and wind energy are being adopted increasingly for commercial electricity generation and institutional use, even in out of space, the technological advances and the sharing of knowledge by a few appreciable technical professionals, this amazing technology has come into the axis of every individual.

Through solar panels and windmills not only can you generate electricity for free forever, you can also get rid of cost paid for electricity supplied by electricity supply companies, many of which use hazardous means of power generation, like thermal and nuclear power generation. You could set an example for others by using solar panels and windmills as a source for the generation of the electricity required by you, and to discourage the use of electricity produced through means which are hazardous to the environment.

Not only doing so will benefit those adopting renewable energy sources, but will also be helpful to the environment. As solar and wind energy is going to be the ultimate power generation means of the future generations, your children will be thanking you for making an early start, or rather a not-too-late start.

You can judge for yourself the importance of protecting the environment. Useful guide programs like Earth4Energy play a very important role in propagating the use of solar panels and windmills and are therefore helping the environment. Earth4Energy is empowering people with the technology of utilizing solar panels and windmills affordably, which is in turn helping the cause of the preservation of the environment, as people find their economic interests coherent with the protection of the environment.

The Pros and Cons of Solar Panels

Solar Panels are getting more popularity than any other alternative renewable energy source all around the world. Not only is it being used for mass power generation but also by domestic households, and is one of the major power sources of the future. Let us examine its pros and cons:

Solar panelsPros

  • The solar panels are one of the most cost-effective energy sources on planet earth, once installed and working.
  • Solar panels have no maintenance cost at all, other than periodic cleaning of the panels.
  • Solar panels are very easy to install, and do not require a lot of space. They can even be installed on top of houses. Furthermore, they are also appearing as the convenient solar panel house tiles, which actually integrate them into the structure of the house.
  • In contrast to other power sources, solar panels don’t even make a decibel of noise.
  • There are no moving parts involved, which means no wear and tear.
  • Using solar panels harness the energy of the sun, which will remain to be Nature’s most powerful energy source for the Earth. Solar panel technology can actually convert its energy into electricity and can be especially useful in certain geographical regions of the Earth, which receive more sunlight.
  • By using solar panels, you can create sufficient amounts of energy to fulfill the requirements of your household, and you could also benefit from a net-metering incentive, which may vary for different states and localities.


  • As solar panels require sunlight to produce electricity, they work only as long as the sun is out in full glow.
  • Environmental pollution can create a hindrance to their performance.
  • The performance of solar panels could be dependant on the geographical location.
  • The performance of solar panels could be affected by weather.

The Potential of Solar and Wind Energy

Stay greenAs the awareness about the dangerous effects of global warming and green house gas emissions increase, and the nations of the world feel threatened by the possible depletion of fossil resources in the future, the emphasis on alternate and renewable energy sources has been greater than ever. At the dawn of the 21st century, as the human civilization enters the age of information technology, electricity has become the spinal chord of the economy of the new age.

From the banking and the financial system of the world, to running even the smallest gadget found in every household, power is central to even the most trivial activities (day-to-day) of the human society. In such a scenario, each and every individual is dependent on this powerful resource, which has become a powerful determinant of the direction of global economy. And there is hardly any need to mention the importance of resources that are used to generate the resource of resources, that is, electricity. In order to strike a balance between the renewable and economical nature of sources of production, and the preservation and protection of environment, solar energy and wind energy have emerged to be considered the most efficient and adoptable by the nations of the world.

And as power generation by the usage of solar and wind energy commences on a commercial and institutional scale, innovations in these technologies are also opening to be explored by the masses. Till a very long time, the investment required to make use of these almost cost-free modes of power generation prevented the penetration of general public.

However, innovative do-it-yourself guides like Earth4Energy are changing the relationships of the masses with electricity production. With the passage of time, such devolution of technology would transform the economy of the new age forever. More and more people are benefiting from it every day and are enjoying the pleasure of one of the most important resources on the planet, that is, electricity.
