solar modules

A French-Lebanese research group has proposed a way to cool down PV modules by using air exhausted from heating, ventilation, and air conditioning (HVAC) systems. They showed that array performance improves when the cooling load rises.

Taiwanese researchers have added bathocuproine (BCP) molecules to three different kinds of solvents used in perovskite cells and have ascertained how this combination increases the carrier mobility and passivates the electron-poor defects. Furthermore, they utilized a polyelectrolyte (P3CT-Na) thin film as hole transporting material instead of commonly-used thin films based on PEDOT:PSS.

India had 39.1 GW of grid-connected solar and 216 MW of off-grid projects in operation by the end of February. The state of Karnataka leads with 7.4 GW of installed solar capacity, followed by Rajasthan with 5.5 GW and Tamil Nadu with 4.4 GW.

SunPower claims that the electricity savings could equal the monthly cost of its 25-year loans for residential solar systems.

Talesun has begun work on its 5 GW factory in Siyang county, Jiangsu province and China’s second-largest grid operator, China Southern Power Grid, has announced around 200 GW of renewable energy capacity will be deployed on its service area over the next 10 years.

Global bids are invited to develop an aggregate 75 MW of grid-connected solar power projects with an upper tariff ceiling fixed at INR 3.00/kWh ($0.041/kWh) for the entire power purchase duration of 25 years. The projects are to be installed in the Uttar Pradesh Solar Park on a build-own-operate basis.

Dutch research institute TNO has released a series of guidelines to reduce fire hazards in rooftop PV installations. The study follows a series of fire accidents that occurred between 2018 and 2020 in the Netherlands, for which the main causes were identified.

Scientists from Switzerland fabricated a dye-sensitized solar cell with a new tailored organic photo-sensitizer coded MS5 and a copper (II/I) electrolyte. A device solely sensitized with MS5 showed an open-circuit voltage of 1.24 V, which the researchers said is a record value among copper-based Grätzel cells.

U.S. researchers have assessed the technical and economic feasibility of solar canals in California and have found that their LCOE is already close to that of ground-mounted solar plants. Three different project configurations were analyzed for eight different sites across the California network of canals.

In a sales environment where only one in 10 viable solar projects moves forward, getting from a good idea to a firm decision by a customer needs to happen fast. Here’s how one commercial solar installer makes technology work.
