What is the reason that polymer solar cells typically use a bulk heterojunction?

Currently, bulk heterojunction devices have imbalanced charge-carrier mobility, with the hole mobility being at least an order of magnitude lower than that of the electron mobility; this results in space charge build-up and a decrease in the fill factor and power conversion efficiency of a device.

What are commonly referred to as major benefits of polymer solar cells?

Compared to the commonly used Si-based solar cells, polymer solar cells (PSCs) have promising advantages, such as light weight, flexibility, and easy integration with other electronic devices. … Such a polymer electrode demonstrated high flexibility and a maximal power conversion efficiency of 2.2% (Zhou et al., 2008).

What is the meaning of bulk heterojunction?

1. A polymer solar cell which consists of donor and acceptor materials intermixed throughout the device.

Which one of the following is bulk in solar cell?

Polymer-fullerene bulk heterojunction solar cells are a type of solar cell researched in academic laboratories. Photovoltaic cells featuring a polymeric blend of organics have shown promise in a field largely dominated by inorganic (e.g. silicon) solar cells.

What are the most common photovoltaic cells used today?

What are the most common photovoltaic cells used today? Unveiled by Bell Labs in 1954, silicon cells were the very first successful photovoltaic (PV) technology, and they remain the most common PV cells in use today. 7.

GOOD TO KNOW:  How does electricity usage affect the environment?

Which conducting polymer is used in organic solar cells?

The polypyrrole, polyaniline, and poly(3,4-ethylenedioxythiophene) are commonly used as conductive polymers CEs materials.
