From the project

Solar BPW34 powered nRF BLE

A small solar-only, battery-free device that harvests energy using a single BPW34 cell, boosted and managing energy with the TI B5504.

Sending BLE advertisements every few seconds in direct sunlight - measuring the temperature using an exteral I2C digital chip connected to a Raytac nRF module.
