“…CIGS studies under low-light conditions have shown the devices tested suffered from low shunt resistance that significantly reduced their efficiency as light intensity decreases [31]. CdTe, however, has a bandgap of 1.5 eV and is known to maintain high performance under diffuse radiation and low light [33]. Over the years, the technology itself has established a strong foothold in the PV market and is well characterized.…”

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

“…In terms of the ratio of absorption to emission, which represents the light generated current density to the reverse saturation current (Isc/Io) in Equation ( 2), the Voc increases logarithmically either by increasing Isc or decreasing Io [45]. Since the TPV cells usually operate at high illumination intensity [22], [26], the Isc is always significantly larger than Io. Therefore, increasing the illumination intensity will eventually increase Voc performance.…”

“…Different illumination intensities would give a significant impact on the cell performance parameters such as Jsc, Voc, FF, η, Rs, and Rsh [26].

“…The intensity of the beam depends on the radiator temperature and gap distance (GD) between the radiator and TPV cells. Different illumination intensity may influence the amount of photo-generated current density and has a significant impact on the cell performance parameters, such as open-circuit voltage (Voc), fill factor (FF) and cell conversion efficiency (η) [25], [26]. To date, studies on the effect of TPV illumination intensity on NB semiconductor devices are done at limited radiation temperatures and illumination intensities.…”

“…Therefore, solar cells are often referred to as photovoltaic cells (PV). Electric current arises because of the photon energy of sunlight it receives successfully liberating electrons in the semiconducting relationship type N and type P to flow [14]. Just like a photodiode, this solar cell also has positive and negative legs that are connected to a circuit or device that requires an energy source [15].…”

Penajam Paser Utara Regency is located on the coast of East Kalimantan Province. This regency has a huge solar resource potential, but the agreement in this regency still lacks electricity networks and can be resolved by the people in this regency still in dire need of electricity for street lighting, and daily electricity needs. One of them is in the village of Waru Tua, where this area is in great need of lighting in the dock area because it requires residents to make A living as a fisherman. Waru Tua really needs electricity for lighting at night Waru Tua Pier because it has to be a gathering place for residents before going to sea to prepare everything that must be prepared before going to sea. Discussing the research carried out examining the potential of solar power in Waru Tua. Based on existing considerations, and the potential proposed by the area, the method used is to measure the sunlight at Waru Tua Pier using Lux meter, then the data is processed using the Simulink application in MATLAB to obtain the value of the amount of sunlight in the area, which is 16 KW with a total solar cell of 250 Wp.
