Solar Energy Efficiency

Solar energy is about harnessing sunlight in order to convert that energy into a source of energy that humans can directly utilize. This typically involves what are called solar panels. However, not all solar panels are the same, and not all solar panels are energy efficient. In fact, some solar panels require more energy to operate than they give back out. This demonstrates a lack of solar energy efficiency, and means that more development needs to be done in the area of solar panels.

To understand not just the biggest challenge in making solar power the most efficient form of energy for human usage, but also one of the most promising solutions to that challenge, we must first understand how solar panels work. See, solar panels are made up of small cells, called solar cells. These cells are made out of a semiconductor, such as silicon, and form a small disk. As light shines on the solar cells, it is converted into electricity and then transferred away from the cells. When light is no longer shining, the solar cells can no longer actively produce power.

Now here is a key limitation: current solar cells are too thick for all but the “cooler,” lower energy electrons to pass through in the energy conversion. Solar cells can also be designed specifically for the transference of “hotter,” higher energy electrons to pass through, but not both. That means that, at best, current solar panel technology can convert at a maximum about 35% of the light energy into energy more useful to us. But currently, solar cells that can double the amount of light energy being used are being developed.

These new solar cells will be able to transfer through both the lower energy and higher energy electrons, thus making more energy. And with this increase in efficiency comes a lower price. Doubling the efficiency effectively cuts the cost of utilizing solar energy in half, offering a greener, friendlier environment for all of us -- but also by potentially lowering your personal energy costs dramatically. To support this advancement, it would suit you to donate directly to solar research institutions, including academic institutions focusing on this research, but also by utilizing existing solar panel technologies. Each increase in funding moves us closer to long-term energy dependence, and a greener environment.
