Solar is perhaps one of the most reliable source of renewable energy we have today. While the entire world is turning towards green energy, the drop in efficiency of solar cells remains a worry. For almost 40 years, in fact since their development, scientists have prodded over the consistent drop in efficiency of solar cells. With more than 270 research papers published trying to understand what induces the drop in
The Research team of New York University, Tandon School of Engineering, develops a phenomenal means creating solar cells. These organic solar cells are resistant to air, light, and water. During the research, they removed the material from the device instead of adding any material to it. This is attained by sticking an adhesive tape to the device to strip off the electron receiving molecules. Degeneration of a device happens due
Lead-based perovskite is finding way as a low-cost and efficient material for solar cells, as per a recent study. Howbeit, the inherent instability and toxic nature of lead have raised major concerns pertaining to the sustainability of lead-based perovskites. This is thus hindering the adoption of these materials for large-scale commercial use. On the other hand, in another move, lead-free perovskites received recommendation because of toxic nature of lead-based perovskites.
