The path to develop better solar energy products from silicon are exhausted. Other materials need to be examined to provide more efficient solar panel operation. Scientists are analyzing a wide spectrum of materials.
Plastics show a great deal of promise, particularly at the molecular level. Organic sem-conductors appear to be the key to future developments. This is a type of plastic that conducts electricity. More effective conductivity seems to be the key not so much heat generation.
It is expensive to make silicon conductors for solar cells. OSCs can be manipulated at the molecular level to reduce energy loss, thus more energy is accumulated. Improved efficiency will see the whole production method change for solar cells.
