What is thin film photovoltaic (PV)?

Thin film photovoltaic (PV) technologies often utilize monolithic integration to combine cells into modules. This is an approach whereby thin, electronically-active layers are deposited onto inexpensive substrates (e.g. glass) and then interconnected cells are formed by subsequent back contact processes and scribing.

Why are thin-film multi-junction photovoltaic (PV) cells popular?

Thin-film multi-junction photovoltaic (PV) cells made from the compounds of III–V materials have been widely adopted due to their high light-electricity conversion efficiency and low areal mass density 1, 2.

How do defects in photovoltaic materials affect p n junctions?

Control of defect processes in photovoltaic materials is essential for realizing high-efficiency solar cells and related optoelectronic devices. Native defects and extrinsic dopants tune the Fermi level and enable semiconducting p–n junctions; however, fundamental limits to doping exist in many compounds.

Why do we need to control defect processes in photovoltaic materials?

Provided by the Springer Nature SharedIt content-sharing initiative Control of defect processes in photovoltaic materials is essential for realizing high-efficiency solar cells and related optoelectronic devices.

How to avoid thermal damage to thin-film PV modules?

In order to avoid thermal damage to thin-film modules it must be ensured that the Isc of the modules is not exceeded by more than 30%. During illumination heat and current are generated by incident light (e.g. the sun) which can cause inhomogeneous temperature of the PV module.

What are the challenges in silicon thin-film solar cells?

Challenges in Silicon Thin-Film Solar Cell Because it takes a significant amount of time to simulate a silicon thin-film solar cell, optimizing the performance of silicon thin-film solar cells using device simulation tools is difficult; however, PV-based compact models can save time.
