This study develops a photovoltaic microgenerator based on the complementary metal oxide semiconductor (CMOS) process. The photovoltaic microgenerator converts the absorbed light energy into electrical energy using the photovoltaic effect. The material for the photovoltaic microgenerator is silicon, and its structure consists of patterned p–n junctions. The design of the photovoltaic microgenerator utilizes a grid-like shape, forming a large-area p–n junction with a patterned p-doping and N-well structure to enhance the photocurrent and improve the device’s performance. The photovoltaic microgenerator is fabricated employing the CMOS process with post-processing step. Post-processing is applied to enhance the microgenerator’s light absorption and energy-conversion efficiency. This involves using wet etching with buffered-oxide etch (BOE) to remove the silicon dioxide layer above the p–n junctions, allowing direct illumination of the p–n junctions. The area of the photovoltaic microgenerator is 0.79 mm2. The experimental results show that under an illumination intensity of 1000 W/m2, the photovoltaic microgenerator exhibits an open-circuit voltage of 0.53 V, a short-circuit current of 233 µA, a maximum output power of 99 µW, a fill factor of 0.8, and an energy-conversion efficiency of 12.5%.

“…On the other hand, using dye-sensitized solar cells, 5 µW/cm 2 with a 70% fill factor was measured. The authors of [6] showed that a PMU with maximum power point tracking (MPPT) algorithm is more efficient compared to a more straightforward PV panel connected to a battery. The authors demonstrated that a total system efficiency of about 61% was achieved using the MPPT in an indoor environment.…”

This paper presents novel insights and a new method for improving indoor light energy harvesting for Internet of Things (IoT) applications using a photovoltaic (PV) panel. The concept is based on enhancing the rectifying performance of the intrinsic diode of the PV panel using a high peak-to-average power ratio (PAPR) light waveform. Improving techniques for rectifying systems are well established in the radiofrequency (RF) community but are applied to a light-based system in this paper. A system model is presented to justify the used method. We prove that only a pulse-width modulation (PWM) signal can enhance the energy harvesting at the PV panel. We designed a light-emitting diode (LED) driver and measured the received power to evaluate our concept. For a constant power of the light source, the PWM waveform achieved a 28.8% improvement of the received power compared to a continuous direct current (DC) light source.

“…There is a great give out of operation of making observations around the earth on different wave power for a given time make into different sorts apparatuses, making clear by reasoning the possible unused quality of waves as a power for a given time starting point. However, most of them are very high in price and greatly sized in scale [3] . Solar power systems are therefore one of the most giving undertaking green powers for a given time starting points for powering DC amounts on off-land, overseas flat structures, such as straight-away help needed lighting, vhf radios, far away, widely different apparatus at end of system unit ship lights and unclear horn system [4].…”

Cleaning boats are frequently used to remove trash from offshore areas to combat sea pollution. With a small self-propelled rubbish cleaning boat as the model, this paper presents a design for converting solar energy into power for the ship's control system. Wireless signals are transmitted via Bluetooth modules and several components of the system are controlled by Arduino platforms. Solar panels can be automatically deployed using this device. In the event of harsh weather, the emergency protection system can be activated to ensure the reliability of the system's operation.
