Research Trend Aiming at High Efficiency Organic Solar Cells

Towards High-Efficiency Organic Solar Cells: Polymers and Devices Development

Erroneous efficiency reports harm organic solar cell research

The efficiencies of both organic and hybrid (organicinorganic) solar cells have increased markedly in recent years, making them an exciting and commercially valuable prospect. Despite this progress, a literature survey that we have performed suggests that a large number of reported solar cell efficiencies are being incorrectly measured and reported in journals, with the device efficiency being ...

Effect of TiO2 Nanofiber Density on Organic-Inorganic Based Hybrid Solar Cells (RESEARCH NOTE)

Abstract In this work, a comparative study of hybrid solar cells based on P3HT and TiO2 nanofibers was accomplished. Electrospinning, a low cost production method for large area nanofibrous films, was employed to fabricate the organic-inorganic hybrid solar cells based on poly (3-hexylthiophene) and TiO2 nanofibers. The performance of the hybrid solar cells was analyzed for four density levels ...

Methodologies for high efficiency perovskite solar cells

Since the report on long-term durable solid-state perovskite solar cell in 2012, perovskite solar cells based on lead halide perovskites having organic cations such as methylammonium CH3NH3PbI3 or formamidinium HC(NH2)2PbI3 have received great attention because of superb photovoltaic performance with power conversion efficiency exceeding 22 %. In this review, emergence of perovskite solar cell ...

High efficiency all-polymer tandem solar cells

In this work, we have reported for the first time an efficient all-polymer tandem cell using identical sub-cells based on P2F-DO:N2200. A high power conversion efficiency (PCE) of 6.70% was achieved, which is among the highest efficiencies for all polymer solar cells and 43% larger than the PCE of single junction cell. The largely improved device performance can be mainly attributed to the enha...
