The first time that the solar cells appeared, was in the 50’s. They were very poor on turning sunlight into electricity. Nowadays, there are a great variety of solar cells, and this variety grows stronger over time due to the latest technology advancement.

Which are solar cell technology advancements?

The solar cells are part of a solar panel; these are put and linked together to generate solar energy. In the beginning, the solar panels were frequently used mainly to heat water and homes than anything else, because of their extreme difficulty in generating electric power, once their performance was too low. Today, the solar cell technology is used in many ways, the technology has increased so much that there are even electronic devices that only work with solar energy (since a solar calculator to the solar panels on the International Space Station).

Historically, the first solar cell was low in its efficiency, and much energy was lost during its conversion from DC (direct current) to the AC (alternating current). Although the solar cells worked, their efficiency was really bad to the point that it was not worth investing in this type of device, and in addition it required an inordinate amount of solar panels to generate a considerable quantity of electrical energy.

As solar cell technology progressed, their components have become more efficient. The silicone is still used, but new technologies were added, which really increased the solar cell performance. Otherwise, these changes in solar cell technology has also allowed the reduction of costs of solar panels because fewer cells were needed to make a single panel. Many researches work hard to improve the efficiency of this device in order to provide its disclosure and applicability.

Solar Cell Technology Used Today

A solar cell is made in different ways, resulting in the use of different materials, which produce different properties and performance, and, of course, different costs.

Solar cells are usually made of crystalline silicon removed from quartz sand. Silicon is processed into mono or polycrystalline cells. The cell is usually a square flat, which is placed between tempered glass and plastic. Electrodes are attached to the front and the back of the silicon (solar cell), which receive sun directly on its surface; once the cells absorb the sunlight the process of electricity generation begins, and the energy is collected by the electrodes which can be stored in batteries and/or can be sent back to the electrical grid.

The Future Of Solar Cell Technology

With the projected depletion of nonrenewable energy, the claim for clean energy and the current electricity costs, the look at the sun as an inexhaustible power source has led to a higher interest to decrease the solar energy cost using high-efficiency solar cells. Many types of solar cells are being tested. With the expected increasing population, the demand for fossil fuels, natural gas, electricity issues are even more expensive. Solar energy is a strong candidate for alternative energy.
