Indoor photovoltaic cells have the potential to power the Internet of Things ecosystem, including distributed and remote sensors, actuators, and communications devices. As the power required to operate these devices continues to decrease, the type and number of nodes that can now be persistently powered by indoor photovoltaic cells is rapidly growing. This will drive significant growth in the demand for indoor photovoltaics, creating a large alternative market for existing and novel photovoltaic technologies. With the re-emergence of interest in indoor photovoltaic cells, we provide an overview of this burgeoning field focusing on the technical challenges that remain to create energy autonomous sensors at viable price points, and the commercial challenges to be overcome for individual photovoltaic technologies to dominate this market. I. INTRODUCTION TO INDOOR PHOTOVOLTAICS The early years of solar-power electronic devices saw photovoltaic (PV) cells used in extremely low power but relatively expensive consumer devices, where their cost could easily be absorbed. For example, the designers of a smartwatch that sold for ~$100 could afford to incorporate a cell costing a few dollars. Figure 1 outlines how, as the number and types of low-power electronic devices have expanded over the years, their costs have reduced. At the same time, the cost of PV cells has also been reducing, and the performance increasing, so that now we can sensibly power a range of electronic devices including wireless sensors, RFID tags or Bluetooth Beacons. A significant portion of these new devices are part of the Internet of Things (IoT) ecosystem that promises large networks of connected devices collecting the Big Data upon which our medical, manufacturing, infrastructure, and energy industries will be monitored and optimized. Billions of wireless sensors are expected to be installed over the coming decade, with almost half to be located inside buildings [1]. Currently, the use of batteries to power these devices places significant constraints on their power consumption, where the range and frequency Technology and market perspective for indoor photovoltaic cells

“…[ 10 ] The corresponding irradiance is approximately 50–300 µW cm −2 , with spectra spanning predominantly over the visible wavelength range (400 ≲ λ ≲ 700 nm). [ 11–13 ] As a result, although commercial crystalline silicon solar cells are suitable for harvesting terrestrial solar radiation, their bandgaps (1.12 eV) are too narrow for optimal harvesting of indoor lighting. [ 14 ] Furthermore, crystalline silicon solar cells suffer from significant Shockley‐Read‐Hall recombination under low light conditions.…”

sources at 1000 lux had an irradiance of 340 and 320 µW cm −2 , respectively. The accuracy of the light meter and power meter is the primary determinant of the uncertainty in the measured PCE values, which amounts to approximately ±6-7%, as can be determined from a straightforward uncertainty analysis based on the device testing conditions and the specifications of the power and light meters. Consequently, the PCE values are reported herein with 1 decimal place.

“…Therefore, DSSCs are very competitive to the first and second generations of solar cells due to numerous advantages including easy fabrication, low cost (Figure 1) [3], and high performance at dim-light condition. Moreover, DSSCs can be used in indoor ambient applications [5][6][7][8][9].…”

In recent decades, plenty of nanomaterials have been investigated as electrocatalysts for the replacement of the expensive platinum (Pt) counter electrode in dyesensitized solar cells (DSSCs). The key function of the electrocatalyst is to reduce tri-iodide ions to iodide ions at the electrolyte/counter electrode interface. The performance of the electrocatalyst is usually determined by two key factors, i.e., the intrinsic heterogeneous rate constant and the effective electrocatalytic surface area of the electrocatalyst. The intrinsic heterogeneous rate constant of the electrocatalyst varies by different types of materials, which can be roughly divided into five groups: non-Pt metals, carbons, conducting polymers, transition metal compounds, and their composites. The effective electrocatalytic surface area is determined by the nanostructure of the electrocatalyst. In this chapter, the nanostructural design and engineering on different types of Pt-free electrocatalysts will be systematically introduced. Also, the relationship between various nanostructures of electrocatalysts and the pertinent physical/electrochemical properties will be discussed.
