An average household could save over $1,000 by going solar in the first year alone. But as we mentioned above, solar is a good investment because it freezes your electricity costs while utility rates keep climbing. According to the Bureau of Labor Statistics, the national price of electricity increased by 3.51% on average per year from 2018-2022.
Organic solar cells (OSCs), in which the photoactive layer is composed of organic conjugated materials, have been consid- ered as prospective technology because of the …

All-polymer solar cells based on both polymers as acceptors were fabricated, in which P3HT/P1 blends showed power conversion efficiency twice as high as that of P3HT/P2. Further investigation showed that a P3HT/ P1 blend film displayed smaller surface roughness and lower crystallinity of P3HT, indicating better miscibility of P3HT and P1 .
