INTRODUCTION:
- The demand for energy is on an increasing trend.
- The oil reservoirs, coal as well that of the gas will completely be exploited in the near future.
- There is need to find clean, renewable and sustainable alternative source of energy.
- Solar energy has for a long time been considered among the best alternative source of energy owing to its abundance but harvesting and conversion technology has been the limiting factor.
- For decades, silicon has remained the dominant material for production of commercial solar conversion devices.
- Research seems to suggest that perovskites stand to be good candidates among other materials.
- The understanding of the operational mechanism of the PSCs is necessary for further improvement of its efficiency.
