Reforms over the past three years have lifted restrictions on foreign investment and sped up the permitting process for solar projects in the Philippines. As the government banks on renewables to drive the rapid expansion of power production, challenges remain for local project developers. Neil Ford reports.
Organic-inorganic perovskite cell relying on furan-based polymer achieves 21.39% efficiency
Researchers in Singapore used a biomass-derived polymer to increase the efficiency of hybrid organic-inorganic perovskite solar cell. The cell was also found to obtain a 90% efficiency retention after 1,100 hours, which compares to 52% for benchmark cells designed without the proposed polymer.
