This technology is safer, faster, and more economical than previous chemical solution methods, and this is the first time that the progress of this technology can be used to continuously and quickly deposit solar cell film absorbers, these compounds include copper indium two selenium compounds.
The researchers took a big step in the use of continuous flow microreactors, producing a thin film absorber for solar cells
An innovative technology that can significantly reduce the cost of solar equipment and reduce material waste.
This technology is safer, faster, and more economical than previous chemical solution methods, and this is the first time that the progress of this technology can be used to continuously and quickly deposit solar cell film absorbers, these compounds include copper indium two selenium compounds.
This study was reported in previous methods of using this compound, one of the main photovoltaic alternatives to silicon
Based on solar devices, relying on methods such as sputtering, evaporation, deposition.
The process can be time-
Foreign chemicals that consume or require expensive vacuum systems or increase production costs.
Chemical bath deposition is a low
Cost deposition technology developed more than a century ago.
It is usually performed as an intermittent process, but changes in the growth solution over time make it difficult to control the thickness.
The depletion of the reactants also limits the achievable thickness.
However, the technology invented by Oregon State University to deposit \"nano-structured films\" on various surfaces in continuous flow microreactors solves some of these problems and makes the use of this process more commercially practical
\"We have now proved that this system can produce thin
It is very important to form a thin film solar absorber on a glass substrate in a short period of time.
Chih said: \"This is the first time this work has been done with this new technologyhung Chang.
Further work is needed in terms of process control, testing of finished solar cells, improving their efficiency to compete with vacuum batteries
Based on technology and extending the process to commercial applications, Chang said.
The researchers said it might be interesting, thin
Thin film solar cells generated by applications like this can eventually be used for the creation of solar roof systems.
Conceptually, the solar panels themselves will become roofs, rather than adding solar panels to the roofs of residential or industrial buildings, eliminating traditional methods such as plywood and wooden tiles.
\"If we can produce cost-effective roof products
Produce solar energy effectively at the same time, which will change the rules of the game.
Thin film solar cell is a feasible method.
All solar applications are ultimately a function of efficiency, cost and environmental safety, and these products may provide all of them, \"Chang said.
