PEROVSKITE- Brightening Solar Technology

                       PEROVSKITE,  a cheap material which can be used in making solar cells would cut the cost of a single Watt of solar generating capacity by three-quarters.

 

                       Perovskite, is a Calcium Titanium Oxide mineral species, composed of Calcium Titanate, with the chemical formula, CaTiO₃.  Also, it is available easy. While conventional Silicon Solar panels use materials that are about 180mm thick, the new solar cells use less than 1mm of material to capture the same amount of sunlight.

                          Solar cells made up of Perovskites have a simple architecture. It can easily be produced in large quantities because the vapour deposition process used to make them is compatible with the conventional processing methods for fabricating such solar cells. Prototype solar panels incorporating nanotechnology are more efficient than standard designs in converting sunlight to electricity, promising inexpensive solar power in the future.

REVIEW- HALF GIRLFRIEND

                  Half Girlfriend is the story of Madhav and Riya. Chetan Bhagat, the author, also plays an important role in the story. To be simple, Half Girlfriend is a beautiful, yet thrilling love story.

   

            Madhav Jha is from a small village named Dumraon in Bihar. He is from a royal family which almost lost all its power and supremacy, but still counts as landlords for the village folks. He represents the non-English type Indians who are not much confident at speaking in English. But he was destined to be in the famous college of New Delhi, St.Stephens, where one could find only English speaking guys. Being desperate and suppressed, he lost all his confidence. However he was trying to get the admission through sports Quota. He was a very talented Basketball player. At trials, to showcase their performance, he finds a beautiful girl. Riya Somani, the tall, gorgeous girl, with attractive looks, from a high class Marwari family of New Delhi, was also there to prove her talent at the basketball court. Madhav, however took a chance to get acquainted with his dream girl. His coach introduced him to Riya, and they talked to each other for the first time.

           Later on, both of them started their life at St.Stephens, New Delhi. Madhav Jha, who was always inferior because of his ‘English’, finds himself much comfortable with Riya. He always needed her presence. Obviously, he fell in love with her. But Riya was a reserved character. She had a lot of friends, Madhav was just one among them. Maybe, we think he was more special, but definitely one cannot call it as ‘love’.  Madhav wanted her to be his girlfriend. But Riya was not ready for that. Still, she agreed to be his HALF GIRLFRIEND. Their relation gets more stronger. Riya sometimes shares some secrets with Madhav, however she was not ready to reveal herself at times. Madhav gets annoyed by her this kind of attitude sometimes, still he was not bothered much because he was deeply in love with her. Riya always considered Madhav as her “Basketball Friend”.

                   The story continues in Bihar as well as in New York. It brings out many twists and turns and even suspenses at some occasions. The relationship between them is well defined in the remaining part of the story. It is interesting as well as  worth reading. Whether Madhav’s love is succeeding or not is the main question that arises in the mind of the reader, which is depicted beautifully in the story, and ofcourse, the reader gets the answer at the climax of the story. Half Girlfriend is a simple, well said, romantic novel which makes us feel great.
