A new investigation based on the natural behavior of the plants, guide to a team of the MIT to imitate the capacity of repair itself applied to the photocells.
In the research of the MIT team working together with the Eni Solar center of MIT, on the study of the great capacity of destruction of the sunlight rays over the majority of elaborated systems in the photocells, put to Michael Strano, one of the researchers of the team to consider the innate capacity of the plants to make the capture of sunlight every moment, without any degradation and apply to the photocells. The natural form of the plants to catch the sunlight’s using the proteins in their chloroplast of their leafs to make the process of photosynthesis, and after a time, the proteins are broken using oxygen to decompose into a specific form of compound to reconstruct then again and continue the process of self-alimentation without any lose of efficiency in the new protein.
In the investigation of the photocell, they used seven different types of compounds, one of them are the phospholipids. The phospholipids form a support for the reactive molecules, and are organized in form of disk, they receive the released electrons of the other compounds when the light pass across then (the reactive proteins and phospholipids is a system called reactive centers) meanwhile the phospholipids form a link with carbon nanotubes to make a way for the electricity. The link between the disks and the nanotubes are made by a solution that join them in an automatic way and the strength and conductivity capability of this system is better compared with others natural elements in the nature (the strength of the steel and the conductivity of cooper).
The seven compounds (all are not mentioned) can be divided apart each one with the presence of a surfactant, making a soup solution, and after that, the surfactant can be removed if the soup pass across a membrane, and the solution form again the initial structure rejuvenated and without efficiency lose like the plant’s system, describing the result like the investigators, a copy of the process of the nature made million years ago. To support the capacity of the new cells, they made a test, making a great number of cycles in 14 hours without interruption, and observing that that didn’t have any lose in the generation of electricity.
A simple photocell.
The importance of the investigation is based on the comparison of the silicon-based photovoltaic cell, when the work on the time is studied; the efficiency of the system falls to 10 percent compared with the initial state, meanwhile the efficiency of the self-repair system don’t falls, represent economical and material saving to the producers. The problem is the low level of transformation of the photocells, they can transform 40 percent of sun light in electricity, because the new element have low concentration of the compounds in the soup, giving a new orientation to the new investigation: working in the improvement of the concentration of these materials in the dispositive to make it enough potential to change the old photocells.
