The rapidly growing solar cell industry relies on a range of highly expensive photovoltaic materials such as silicon, cadmium telluride and cadmium chloride. The latter, by the way, is highly toxic.
Troy Townsen, a researcher at St. Mary's College, says he and his colleagues are close to creating a special, non-toxic and inexpensive paint that could soon replace bulky and expensive solar panels.
The photosensitive paint will be applied to a glass-type surface using special additives, turning it into solar panels. Multiple batteries can be combined to increase the generated power.
Their efficiency is still inferior to traditional solar panels (5-12% versus 16-20%). However, this is easily offset by the increase in surface area. After all, in principle, the entire roof can be painted with photosensitive paint without any problems. Townsen is convinced of ultimate success:
“We have set ourselves the goal of making the results of our work the property of ordinary users. Moreover, they will have the opportunity to make solar panels on their own literally in their kitchens. "
