Tang photovoltaic devices
There has been an active search for cost-effective photovoltaic devices since the development of the first solar cells in the 1950s (refs 1–3). In conventional solid-state solar cells, electron–hole pairs are created.
The device structure is a solid-state multilayer; it consists of a photoreceptor layer.
Device fabricationDevices were fabricated on titanium foil substrates (Alfa Aesar), which served as ohmic back contacts. A 250-nm layer of titanium (9.

6 FAQs about [Tang photovoltaic devices]
Are organic photovoltaic devices a promising technology for indoor light harvesting?
Organic photovoltaic (OPV) devices are a promising technology for indoor light harvesting and power conversion, but high voltage losses, especially under weak illumination, hinder their development. In this work, the... [...] [...]
What is the structure of an organic photovoltaic device?
The general structure of an organic photovoltaic device similar to that reported by Tang16in 1986 is shown in Fig. 1. It consists of a transparent electrode, typically a conducting oxidesuch as indium-tin oxide(ITO), two organic light-absorbing layers, and a second electrode.
What are organic photovoltaics based on organic active layers?
As a matter of fact, photovoltaics based on organic active layers, known as organic photovoltaics (OPVs), are an important branch of organic electronics research and are one of the most promising emerging PV technologies.
Are organic semiconductors suitable for photovoltaic applications?
In addition to charge transport properties, some organic semiconductors can also realize high-light-absorption coefficients, which makes them candidates for photovoltaic applications.
Are Thiophene-Based polymer acceptors still used in organic solar cells?
In 2009, when-thiophene-based polymer donors like P3HT and fullerene-based acceptors such as PCBM were still the dominant material combination, Rau et al. calculated the radiative efficiency limits of BHJ-type organic solar cells using the S-Q model [ 72 ].
Can nonfused ring acceptors be used for organic solar cells?
[...] Nonfused ring acceptors have shown great potential for future commercial applications of organic solar cells (OSCs) due to their simple structure and low synthetic costs.
