**6. Conclusion**

Transparent solar panels are very challenging to find their real time applications. They have huge scope to generate solar power and making electronic devices for self charging applications. Currently, they have limitations on large applications due to low efficiency and cost. These solar cells can block the most of IR. Researchers have

developed graphene based organic solar cells with improved efficiency with significant transparency. Increasing the amount of active area would push up the PCE, but transparency would drop. The highest transparency of about 80% has been measured in transparent solar cells with maximum power conversion efficiency of about 12–15%. The various materials have been utilized to improve the transparency and performance of solar cells. Transparent solar panel would bring a remarkable change in electronic and optical applications.
