Production of indoor solar power generation

How did photovoltaic technology start?

Despite the low preliminary power conversion efficiency (PCE) of <1%, these early discoveries initiated the research of photovoltaic field and then inspired the emergence of silicon (Si) solar cells in 1954 (2), thus laying the foundation for modern photovoltaic industry.

What is indoor photovoltaics (IPV)?

1.1. Indoor photovoltaics Indoor photovoltaics (IPV) emerged in PV technology in present scenario due to the ease of power generation under simple indoor light conditions and also serve the fastest energy supplements for growing technologies like Internet of Things (IoT).

Are indoor photovoltaics the world's oldest and long-ignored material?

Here, we revisit the world’s oldest but long-ignored photovoltaic material with the emergence of indoor photovoltaics (IPVs); the absorption spectrum of Se perfectly matches the emission spectra of commonly used indoor light sources in the 400 to 700 nm range.

Are solar cells suitable for indoor light harvesting?

In this study, we performed a detailed review of the development of various solar cells for indoor applications. It is thus observed that although ISCs are dominating the outdoor solar cell market, they are not suitable for use as indoor light-harvesting units because of their low bandgap energy and poor mechanical flexibility.

Are solar cells suitable for indoor applications?

Therefore, the fabrication of specially designed solar cells for indoor applications is not an easy task. Different parameters of solar cells must be optimized for indoor light conditions. The device should be designed in such a manner that it can operate efficiently under the illumination of the most commonly used indoor light sources.

Are indoor photovoltaics a good energy source for wireless devices?

Until recently, with the advent of the Internet of Things (IoT), indoor photovoltaics (IPVs) that convert indoor light into usable electrical power have been recognized as the most promising energy supplier for the wireless devices including actuators, sensors, and communication devices connected and automated by IoT technology (5, 6).
