Solar technology refers to technology that uses solar radiation to generate electricity or utilize thermal energy. Solar energy is environmentally friendly, renewable, noiseless, and pollution-free and does not require fuel, making it a form of renewable energy. A solar cell (SC) comprises multiple thin layers of semiconductor materials. When sunlight shines on an SC, photons excite electrons in the semiconductor materials, generating an electric current. In recent years, there have been rapid advancements in SC research, primarily focused on improving efficiency and reducing costs. This article offers a comprehensive overview of the recent advancements in SC research. It summarizes the various types of SCs, including their structures, fabrication processes, and application areas. It then summarizes the bottleneck issues and solutions in the preparation of semiconductor materials for SCs, external environmental impacts, and cell stability. Finally, it discusses the opportunities and challenges of SCs. Although SC research still faces some difficulties, with continuous technological advancements, SCs will become an essential component of future clean energy.

The hole transport layer (HTL) with a function of charge extraction and transport plays a pivotal role in enhancing the performance of ultraviolet photodetectors (UV PDs). Herein, a CuI p‐type layer modified with graphene oxide (GO) is efficiently employed as the hole extractor for UV PDs based on ZnO nanorod arrays (NRs). The UV PD fabricated on FTO/ZnO NRs/CuI@GO/Au architecture exhibits exceptional performance characteristics including remarkably high responsivity (up to 387 mA W−1), significant specific detectivity (1.7 × 1013 cm Hz1/2 W−1), and rapid rise/decay time (23/16 ns) under self‐powered mode. The presence of GO effectively adsorbs and aggregates CuI nanoparticles, resulting in the formation of compact films and reduction in surface trap defects. Furthermore, owing to the strong electronegativity of GO terminated oxygen‐containing groups, the work function and band structure of CuI are further optimized, which strengthens the built‐in electric field of the ZnO/CuI heterojunction. Meanwhile, the pyroelectric effect of CuI that obstructs the hole transport is suppressed with the addition of GO. These improvements not only improve charge separation and hole extraction efficiencies but also significantly mitigate surface nonradiative charge recombination. This approach provides a novel strategy for optimizing CuI as an immense potential HTL with GO modulation.
