Title:

Indoor Light Harvesters (Dye-sensitized solar cells)

Value Proposition:

Indoor/Ambient Light Harvesters for Self-powered IoTs are third-generation molecular light-harvesting devices based on Dye-sensitized solar cells (DSCs) technology. These harvesters are designed to capture and recycle all types of light, including indoor and outdoor sources, to power self-sufficient devices. DSCs have proven to be the most efficient technology for harvesting energy from indoor and ambient lighting, with efficiencies reaching up to 40%. This technology addresses the limitations of conventional solar technologies, which are often too bulky, rigid, or inefficient for use in remote or indoor locations under artificial lighting. The market for indoor photovoltaics is projected to reach $850 million by the end of 2024, highlighting the growing demand for this innovative solution.

Summary Application:

Indoor/Ambient Light Harvesters, powered by Dye-sensitized solar cells (DSCs), provide an efficient and sustainable energy solution for self-powered Internet of Things (IoT) devices. These third-generation molecular light-harvesting devices can capture and recycle various light sources, including indoor artificial lighting, achieving up to 40% efficiency in such environments.

This technology overcomes the limitations of conventional solar solutions, which are often unsuitable for indoor or remote applications due to their size, rigidity, or inefficiency under artificial lighting. With the indoor photovoltaics market projected to reach $850 million by 2024, these light harvesters are poised to meet the growing demand for compact, versatile, and energy-efficient solutions in IoT and other low-power electronic applications.

Advantages:
  • Eco-friendly alternative: Reduces pollution caused by disposable batteries, potentially saving millions of square kilometers of land and water from contamination.
  • Versatile and efficient: Capable of harvesting energy from various light sources, including artificial indoor lighting, with efficiencies exceeding 40%.
  • Cost-effective production: Utilizes easily sourced materials and supports indigenous manufacturing, leading to reduced production costs and import substitution.
  • Sustainable lifecycle: Offers improved recyclability compared to batteries, contributing to a greener and more sustainable living environment.
