It has been demonstrated that the fabrication of III–V semiconductor-based photocatalysts is effective in increasing solar light absorption, long-term stability, large-scale production and promoting charge transfer. This focused review explores on the current developments in III–V semiconductor materials for solar-powered photocatalytic systems.
Latest generation silicon carbide semiconductors enable a significant increase in power conversion efficiency in solar power generation systems and associated energy storage.
Conventional design of solar charging batteries involves the use of batteries and solar modules as two separate units connected by electric wires. Advanced design involves the integration of in situ battery storage in solar modules, thus offering compactness and fewer packaging requirements with the potential to become less costly.
In the third generation, which are multi-junction solar cells, a network of diodes is the best model and the current-voltage relations can be calculated by determining the number of series and/or parallel junctions. The parallel connected diodes are increasing the final current and the series connected diodes can increase the final voltage as well.
Additionally, the growing importance of solar energy storage is underscored by the fluctuating nature of solar energy production and the variability in energy demand. Here, we introduce a possible PV-based hybrid technology that seeks to mitigate these challenges.
Semiconductors belonging to the III–V compound group, in particular, demonstrate remarkable stability under photocatalytic conditions and feature a direct energy bandgap that covers a substantial portion of the solar spectrum, as illustrated in Fig. 1 a.

Role of Semiconductors in Various Renewable Energy Systems
Solar or PV arrays are capable of generating thousands of kilowatts of electric power. Presently, individual PV cells have an efficiency of about 15–20%. In individual photovoltaic cells, about 2 watts of energy are produced. The efficiency of PV arrays as a whole, however, just falls short—this accounts for inevitable faults in the system [6].

Temperature effect of photovoltaic cells: a review
2.1 Temperature effect on the semiconductor band gap of SCs. Band gap, also known as energy gap and energy band gap, is one of the key factors affecting loss and SCs conversion efficiency. Only photons with energy higher than the forbidden band width can produce PV effect, which also determines the limit of the maximum wavelength that SCs can absorb for power generation [].
